## Aggregator Plugins
|
||||
|
||||
This section is for developers who want to create a new aggregator plugin.
|
||||
|
||||
### Aggregator Plugin Guidelines
|
||||
|
||||
* A aggregator must conform to the [`telegraf.Aggregator`](https://godoc.org/github.com/influxdata/telegraf#Aggregator) interface.
|
||||
* Aggregators should call `aggregators.Add` in their `init` function to register themselves.
|
||||
See below for a quick example.
|
||||
* To be available within Telegraf itself, plugins must add themselves to the
|
||||
`github.com/influxdata/telegraf/plugins/aggregators/all/all.go` file.
|
||||
* The `SampleConfig` function should return valid toml that describes how the
|
||||
aggregator can be configured. This is include in `telegraf config`.
|
||||
* The `Description` function should say in one line what this aggregator does.
|
||||
* The Aggregator plugin will need to keep caches of metrics that have passed
|
||||
through it. This should be done using the builtin `HashID()` function of each
|
||||
metric.
|
||||
* When the `Reset()` function is called, all caches should be cleared.

||||
|
||||

## Unit Tests
|
||||
|
||||
Before opening a pull request you should run the linter checks and
|
||||
the short tests.
|
||||
|
||||
### Execute linter
|
||||
|
||||
execute `make lint`
|
||||
|
||||
### Execute short tests
|
||||
|
||||
execute `make test`
|
||||
execute `make test-short`
|
||||
|
||||
### Execute integration tests
|
||||
### Execute long tests
|
||||
|
||||
Running the integration tests requires several docker containers to be
|
||||
running. You can start the containers with:
|
||||
```
|
||||
make docker-run
|
||||
```
|
||||
As Telegraf collects metrics from several third-party services it becomes a
|
||||
difficult task to mock each service as some of them have complicated protocols
|
||||
which would take some time to replicate.
|
||||
|
||||
And run the full test suite with:
|
||||
```
|
||||
make test-all
|
||||
```
|
||||
To overcome this situation we've decided to use docker containers to provide a
|
||||
fast and reproducible environment to test those services which require it.
|
||||
For other situations
|
||||
(i.e: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/redis/redis_test.go)
|
||||
a simple mock will suffice.
|
||||
|
||||
Use `make docker-kill` to stop the containers.
|
||||
To execute Telegraf tests follow these simple steps:
|
||||
|
||||
- Install docker following [these](https://docs.docker.com/installation/)
|
||||
instructions
|
||||
- execute `make test`
|
||||
|
||||
**OSX users**: you will need to install `boot2docker` or `docker-machine`.
|
||||
The Makefile will assume that you have a `docker-machine` box called `default` to
|
||||
get the IP address.
|
||||
|
||||
### Unit test troubleshooting
|
||||
|
||||
Try cleaning up your test environment by executing `make docker-kill` and
|
||||
re-running

Telegraf is an agent written in Go for collecting, processing, aggregating,
|
||||
and writing metrics.
|
||||
Telegraf is an agent written in Go for collecting metrics from the system it's
|
||||
running on, or from other services, and writing them into InfluxDB or other
|
||||
[outputs](https://github.com/influxdata/telegraf#supported-output-plugins).
|
||||
|
||||
Design goals are to have a minimal memory footprint with a plugin system so
|
||||
that developers in the community can easily add support for collecting metrics
|
||||
. For an example configuration referencet from local or remote services.
|
||||
from well known services (like Hadoop, Postgres, or Redis) and third party
|
||||
APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).
|
||||
|
||||
Telegraf is plugin-driven and has the concept of 4 distinct plugins:
|
||||
|
||||
1. [Input Plugins](#input-plugins) collect metrics from the system, services, or 3rd party APIs
|
||||
2. [Processor Plugins](#processor-plugins) transform, decorate, and/or filter metrics

## How to use it:
|
||||
|
||||
See usage with:
|
||||
```console
|
||||
$ telegraf -help
|
||||
Telegraf, The plugin-driven server agent for collecting and reporting metrics.
|
||||
|
||||
```
|
||||
./telegraf --help
|
||||
```
|
||||
Usage:
|
||||
|
||||
#### Generate a telegraf config file:
|
||||
telegraf <flags>
|
||||
|
||||
```
|
||||
./telegraf config > telegraf.conf
|
||||
```
|
||||
The flags are:
|
||||
|
||||
#### Generate config with only cpu input & influxdb output plugins defined:
|
||||
-config <file> configuration file to load
|
||||
-test gather metrics once, print them to stdout, and exit
|
||||
-sample-config print out full sample configuration to stdout
|
||||
-config-directory directory containing additional *.conf files
|
||||
-input-filter filter the input plugins to enable, separator is :
|
||||
-output-filter filter the output plugins to enable, separator is :
|
||||
-usage print usage for a plugin, ie, 'telegraf -usage mysql'
|
||||
-debug print metrics as they're generated to stdout
|
||||
-quiet run in quiet mode
|
||||
-version print the version to stdout
|
||||
|
||||
```
|
||||
./telegraf --input-filter cpu --output-filter influxdb config
|
||||
```
|
||||
Examples:
|
||||
|
||||
#### Run a single telegraf collection, outputing metrics to stdout:
|
||||
# generate a telegraf config file:
|
||||
telegraf -sample-config > telegraf.conf
|
||||
|
||||
```
|
||||
./telegraf --config telegraf.conf --test
|
||||
```
|
||||
# generate config with only cpu input & influxdb output plugins defined
|
||||
telegraf -sample-config -input-filter cpu -output-filter influxdb
|
||||
|
||||
#### Run telegraf with all plugins defined in config file:
|
||||
# run a single telegraf collection, outputing metrics to stdout
|
||||
telegraf -config telegraf.conf -test
|
||||
|
||||
```
|
||||
./telegraf --config telegraf.conf
|
||||
```
|
||||
|
||||
#### Run telegraf, enabling the cpu & memory input, and influxdb output plugins:
|
||||
# run telegraf with all plugins defined in config file
|
||||
telegraf -config telegraf.conf
|
||||
|
||||
# run telegraf, enabling the cpu & memory input, and influxdb output plugins
|
||||
telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb
|
||||
```
|
||||
./telegraf --config telegraf.conf --input-filter cpu:mem --output-filter influxdb
|
||||
```

Telegraf is able to parse the following input data formats into metrics, these
|
||||
formats may be used with input plugins supporting the `data_format` option:
|
||||
We'll be adding support for many more over the coming months. Read on if you
|
||||
want to add support for another service or third-party API.

# Telegraf Aggregator & Processor Plugins
|
||||
|
||||
As of release 1.1.0, Telegraf has the concept of Aggregator and Processor Plugins.
|
||||
|
||||
These plugins sit in-between Input & Output plugins, aggregating and processing
|
||||
metrics as they pass through Telegraf:
|
||||
|
||||

|
||||
```
|
||||
|
||||
Both Aggregators and Processors analyze metrics as they pass through Telegraf.
|
||||
|
||||
Use [measurement filtering](CONFIGURATION.md#measurement-filtering)
|
||||
to control which metrics are passed through a processor or aggregator. If a
|
||||
metric is filtered out the metric bypasses the plugin and is passed downstream
|
||||
to the next plugin.
|
||||
|
||||
**Processor** plugins process metrics as they pass through and immediately emit
|
||||
results based on the values they process. For example, this could be printing

all metrics or adding a tag to all metrics that pass through.
|
||||
|
||||
**Aggregator** plugins, on the other hand, are a bit more complicated. Aggregators
|
||||
are typically for emitting new _aggregate_ metrics, such as a running mean,
|
||||
minimum, maximum, quantiles, or standard deviation. For this reason, all _aggregator_
|
||||
plugins are configured with a `period`. The `period` is the size of the window
|
||||
of metrics that each _aggregate_ represents. In other words, the emitted
|
||||
_aggregate_ metric will be the aggregated value of the past `period` seconds.
|
||||
Since many users will only care about their aggregates and not every single metric
|
||||
gathered, there is also a `drop_original` argument, which tells Telegraf to only
|
||||
emit the aggregates and not the original metrics.
|
||||
|
||||
**NOTE** That since aggregators only aggregate metrics within their period, that
|
||||
historical data is not supported. In other words, if your metric timestamp is more
|
||||
than `now() - period` in the past, it will not be aggregated. If this is a feature
|
||||
that you need, please comment on this [github issue](https://github.com/influxdata/telegraf/issues/1992)

# Telegraf Configuration
|
||||
|
||||
You can see the latest config file with all available plugins here:
|
||||
[telegraf.conf](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf)
|
||||
|
||||
## Generating a Configuration File
|
||||
|
||||
A default Telegraf config file can be auto-generated by telegraf:
|
||||
|
||||
```
|
||||
telegraf config > telegraf.conf
|
||||
```
|
||||
A default Telegraf config file can be generated using the -sample-config flag:
|
||||
`telegraf -sample-config > telegraf.conf`
|
||||
|
||||
To generate a file with specific inputs and outputs, you can use the
|
||||
--input-filter and --output-filter flags:
|
||||
-input-filter and -output-filter flags:
|
||||
`telegraf -sample-config -input-filter cpu:mem:net:swap -output-filter influxdb:kafka`
|
||||
|
||||
```
|
||||
telegraf --input-filter cpu:mem:net:swap --output-filter influxdb:kafka config
|
||||
```
|
||||
## `[global_tags]` Configuration
|
||||
|
||||
## Environment Variables
|
||||
|
||||
Environment variables can be used anywhere in the config file, simply prepend
|
||||
them with $. For strings the variable must be within quotes (ie, "$STR_VAR"),
|
||||
for numbers and booleans they should be plain (ie, $INT_VAR, $BOOL_VAR)
|
||||
|
||||
When using the `.deb` or `.rpm` packages, you can define environment variables
|
||||
in the `/etc/default/telegraf` file.
|
||||
|
||||
## Configuration file locations
|
||||
|
||||
The location of the configuration file can be set via the `--config` command
|
||||
line flag.
|
||||
|
||||
When the `--config-directory` command line flag is used files ending with
|
||||
`.conf` in the specified directory will also be included in the Telegraf
|
||||
configuration.
|
||||
|
||||
On most systems, the default locations are `/etc/telegraf/telegraf.conf` for
|
||||
the main configuration file and `/etc/telegraf/telegraf.d` for the directory of
|
||||
configuration files.
|
||||
|
||||
# Global Tags
|
||||
|
||||
Global tags can be specified in the `[global_tags]` section of the config file
|
||||
in key="value" format. All metrics being gathered on this host will be tagged
|

Global tags can be specific in the `[global_tags]` section of the config file in

## Input Configuration
|
||||
## `[inputs.xxx]` Configuration
|
||||
|
||||
The following config parameters are available for all inputs:
|
||||
There are some configuration options that are configurable per input:
|
||||
|
||||
* **name_override**: Override the base name of the measurement.
|
||||
(Default is the name of the input).
|
||||
* **name_prefix**: Specifies a prefix to attach to the measurement name.
|
||||
* **name_suffix**: Specifies a suffix to attach to the measurement name.
|
||||
* **tags**: A map of tags to apply to a specific input's measurements.
|
||||
* **interval**: How often to gather this metric. Normal plugins use a single
|
||||
global interval, but if one particular input should be run less or more often,
|
||||
you can configure that here.
|
||||
* **name_override**: Override the base name of the measurement.
|
||||
(Default is the name of the input).
|
||||
* **name_prefix**: Specifies a prefix to attach to the measurement name.
|
||||
* **name_suffix**: Specifies a suffix to attach to the measurement name.
|
||||
* **tags**: A map of tags to apply to a specific input's measurements.
|
||||
|
||||
The [measurement filtering](#measurement-filtering) parameters can be used to
|
||||
limit what metrics are emitted from the input plugin.
|

#### Input Filters
|
||||
|
||||
## Output Configuration
|
||||
There are also filters that can be configured per input:
|
||||
|
||||
The [measurement filtering](#measurement-filtering) parameters can be used to
|
||||
limit what metrics are emitted from the output plugin.
|
||||
|
||||
## Aggregator Configuration
|
||||
|
||||
The following config parameters are available for all aggregators:
|
||||
|
||||
* **period**: The period on which to flush & clear each aggregator. All metrics
|
||||
that are sent with timestamps outside of this period will be ignored by the
|
||||
aggregator.
|
||||
* **delay**: The delay before each aggregator is flushed. This is to control
|
||||
how long for aggregators to wait before receiving metrics from input plugins,
|
||||
in the case that aggregators are flushing and inputs are gathering on the
|
||||
same interval.
|
||||
* **drop_original**: If true, the original metric will be dropped by the
|
||||
aggregator and will not get sent to the output plugins.
|
||||
* **name_override**: Override the base name of the measurement.
|
||||
(Default is the name of the input).
|
||||
* **name_prefix**: Specifies a prefix to attach to the measurement name.
|
||||
* **name_suffix**: Specifies a suffix to attach to the measurement name.
|
||||
* **tags**: A map of tags to apply to a specific input's measurements.
|
||||
|
||||
The [measurement filtering](#measurement-filtering) parameters can be used to
|
||||
limit what metrics are handled by the aggregator. Excluded metrics are passed
|
||||
downstream to the next aggregator.
|
||||
|
||||
## Processor Configuration
|
||||
|
||||
The following config parameters are available for all processors:
|
||||
|
||||
* **order**: This is the order in which the processor(s) get executed. If this
|
||||
is not specified then processor execution order will be random.
|
||||
|
||||
The [measurement filtering](#measurement-filtering) parameters can be used
|
||||
to limit what metrics are handled by the processor. Excluded metrics are
|
||||
passed downstream to the next processor.
|
||||
|
||||
#### Measurement Filtering
|
||||
|
||||
Filters can be configured per input, output, processor, or aggregator,
|
||||
see below for examples.
|
||||
|
||||
* **namepass**:
|
||||
An array of glob pattern strings. Only points whose measurement name matches
|
||||
a pattern in this list are emitted.
|
||||
* **namedrop**:
|
||||
The inverse of `namepass`. If a match is found the point is discarded. This
|
||||
is tested on points after they have passed the `namepass` test.
|
||||
* **fieldpass**:
|
||||
An array of glob pattern strings. Only fields whose field key matches a
|
||||
pattern in this list are emitted.
|
||||
* **fielddrop**:
|
||||
The inverse of `fieldpass`. Fields with a field key matching one of the
|
||||
patterns will be discarded from the point. This is tested on points after
|
||||
they have passed the `fieldpass` test.
|
||||
* **tagpass**:
|
||||
A table mapping tag keys to arrays of glob pattern strings. Only points
|
||||
that contain a tag key in the table and a tag value matching one of its
|
||||
patterns is emitted.
|
||||
* **tagdrop**:
|
||||
The inverse of `tagpass`. If a match is found the point is discarded. This
|
||||
is tested on points after they have passed the `tagpass` test.
|
||||
* **taginclude**:
|
||||
An array of glob pattern strings. Only tags with a tag key matching one of
|
||||
the patterns are emitted. In contrast to `tagpass`, which will pass an entire
|
||||
point based on its tag, `taginclude` removes all non matching tags from the
|
||||
point. This filter can be used on both inputs & outputs, but it is
|
||||
_recommended_ to be used on inputs, as it is more efficient to filter out tags
|
||||
at the ingestion point.
|
||||
* **tagexclude**:
|
||||
The inverse of `taginclude`. Tags with a tag key matching one of the patterns
|
||||
will be discarded from the point.
|
||||
|
||||
**NOTE** Due to the way TOML is parsed, `tagpass` and `tagdrop` parameters
|
||||
must be defined at the _end_ of the plugin definition, otherwise subsequent
|
||||
plugin config options will be interpreted as part of the tagpass/tagdrop
|
||||
tables.
|
||||
* **namepass**: An array of strings that is used to filter metrics generated by the
|
||||
current input. Each string in the array is tested as a glob match against
|
||||
measurement names and if it matches, the field is emitted.
|
||||
* **namedrop**: The inverse of pass, if a measurement name matches, it is not emitted.
|
||||
* **fieldpass**: An array of strings that is used to filter metrics generated by the
|
||||
current input. Each string in the array is tested as a glob match against field names
|
||||
and if it matches, the field is emitted.
|
||||
* **fielddrop**: The inverse of pass, if a field name matches, it is not emitted.
|
||||
* **tagpass**: tag names and arrays of strings that are used to filter
|
||||
measurements by the current input. Each string in the array is tested as a glob
|
||||
match against the tag name, and if it matches the measurement is emitted.
|
||||
* **tagdrop**: The inverse of tagpass. If a tag matches, the measurement is not
|
||||
emitted. This is tested on measurements that have passed the tagpass test.

# Value:
|
||||
|
||||
The "value" data format translates single values into Telegraf metrics. This
|
||||
is done by assigning a measurement name and setting a single field ("value")
|
||||
as the parsed metric.
|
||||
|
||||
#### Value Configuration:
|
||||
|
||||
You **must** tell Telegraf what type of metric to collect by using the
|
||||
`data_type` configuration option. Available options are:
|
||||
|
||||
1. integer
|
||||
2. float or long
|
||||
3. string
|
||||
4. boolean
|
||||
|
||||
**Note:** It is also recommended that you set `name_override` to a measurement
|
||||
name that makes sense for your metric, otherwise it will just be set to the
|
||||
name of the plugin.
|
||||
|
||||

# Graphite:
|
||||
## Graphite:
|
||||
|
||||
The Graphite data format translates graphite _dot_ buckets directly into
|
||||
telegraf measurement names, with a single value field, and without any tags.
|
||||
By default, the separator is left as ".", but this can be changed using the
|
||||
"separator" argument. For more advanced options,
|
||||
Telegraf supports specifying "templates" to translate
|
||||
telegraf measurement names, with a single value field, and without any tags. For
|
||||
more advanced options, Telegraf supports specifying "templates" to translate
|
||||
graphite buckets into Telegraf metrics.
|
||||
|
||||
Templates are of the form:
|
||||
#### Separator:
|
||||
|
||||
You can specify a separator to use for the parsed metrics.
|
||||
By default, it will leave the metrics with a "." separator.
|
||||
Setting `separator = "_"` will translate:
|
||||
|
||||
```
|
||||
"host.mytag.mytag.measurement.measurement.field*"
|
||||
cpu.usage.idle 99
|
||||
=> cpu_usage_idle value=99
|
||||
```
|
||||
|
||||
Where the following keywords exist:
|
||||
|
||||
1. `measurement`: specifies that this section of the graphite bucket corresponds
|
||||
to the measurement name. This can be specified multiple times.
|
||||
2. `field`: specifies that this section of the graphite bucket corresponds
|
||||
to the field name. This can be specified multiple times.
|
||||
3. `measurement*`: specifies that all remaining elements of the graphite bucket
|
||||
correspond to the measurement name.
|
||||
4. `field*`: specifies that all remaining elements of the graphite bucket
|
||||
correspond to the field name.
|
||||
|
||||
Any part of the template that is not a keyword is treated as a tag key. This
|
||||
can also be specified multiple times.
|
||||
|
||||
NOTE: `field*` cannot be used in conjunction with `measurement*`!
|
||||
|
||||
#### Measurement & Tag Templates:
|
||||
#### Measurement/Tag Templates:
|
||||
|
||||
The most basic template is to specify a single transformation to apply to all
|
||||
incoming metrics. So the following template:
|
||||
incoming metrics. _measurement_ is a special keyword that tells Telegraf which
|
||||
parts of the graphite bucket to combine into the measurement name. It can have a
|
||||
trailing `*` to indicate that the remainder of the metric should be used.
|
||||
Other words are considered tag keys. So the following template:
|
||||
|
||||
```toml
|
||||
templates = [
|
||||
"region.region.measurement*"
|
||||
"region.measurement*"
|
||||
]
|
||||
```
|
||||
|
||||
would result in the following Graphite -> Telegraf transformation.
|
||||
|
||||
```
|
||||
us.west.cpu.load 100
|
||||
=> cpu.load,region=us.west value=100
|
||||
```
|
||||
|
||||
Multiple templates can also be specified, but these should be differentiated
|
||||
using _filters_ (see below for more details)
|
||||
|
||||
```toml
|
||||
templates = [
|
||||
"*.*.* region.region.measurement", # <- all 3-part measurements will match this one.
|
||||
"*.*.*.* region.region.host.measurement", # <- all 4-part measurements will match this one.
|
||||
]
|
||||
us-west.cpu.load 100
|
||||
=> cpu.load,region=us-west value=100
|
||||
```
|
||||
|
||||
#### Field Templates:
|
||||
|
||||
There is also a _field_ keyword, which can only be specified once.
|
||||
The field keyword tells Telegraf to give the metric that field name.
|
||||
So the following template:
|
||||
|
||||
```toml
|
||||
separator = "_"
|
||||
templates = [
|
||||
"measurement.measurement.field.field.region"
|
||||
"measurement.measurement.field.region"
|
||||
]
|
||||
```
|
||||
|
||||
would result in the following Graphite -> Telegraf transformation.
|
||||
|
||||
```
|
||||
cpu.usage.idle.percent.eu-east 100
|
||||
=> cpu_usage,region=eu-east idle_percent=100
|
||||
```
|
||||
|
||||
The field key can also be derived from all remaining elements of the graphite
|
||||
bucket by specifying `field*`:
|
||||
|
||||
```toml
|
||||
separator = "_"
|
||||
templates = [
|
||||
"measurement.measurement.region.field*"
|
||||
]
|
||||
```

||||

||||
added as float64 fields.
|
||||
|

# Dropwizard:
|
||||
|
||||
The dropwizard format can parse the JSON representation of a single dropwizard metric registry. By default, tags are parsed from metric names as if they were actual influxdb line protocol keys (`measurement<,tag_set>`) which can be overriden by defining custom [measurement & tag templates](./DATA_FORMATS_INPUT.md#measurement--tag-templates). All field value types are supported, `string`, `number` and `boolean`.
|
||||
|
||||
A typical JSON of a dropwizard metric registry:

||||

|
||||
```
|
||||
|
||||
You may also parse a dropwizard registry from any JSON document which contains a dropwizard registry in some inner field.
|
||||
Eg. to parse the following JSON document:
|
||||
|
||||
```json
|
||||
{
|
||||
"time" : "2017-02-22T14:33:03.662+02:00",
|
||||

|
||||
"tag1" : "green",
|
||||
"tag2" : "yellow"
|
||||
},
|
||||
"metrics" : {
|
||||
"counters" : {
|
||||
"measurement" : {
|
||||
"count" : 1
|
||||
}
|
||||
},
|
||||
"meters" : {},
|
||||
"gauges" : {},
|
||||
"histograms" : {},
|
||||
"timers" : {}
|
||||
}
|
||||
}
|
||||
```
|
||||
and translate it into:
|
||||
|
||||
```
|
||||
measurement,metric_type=counter,tag1=green,tag2=yellow count=1 1487766783662000000
|
||||
```
|
||||
|
||||
you simply need to use the following additional configuration properties:
|
||||
|
||||
```toml
|
||||
dropwizard_metric_registry_path = "metrics"
|
||||
dropwizard_time_path = "time"
|
||||
dropwizard_time_format = "2006-01-02T15:04:05Z07:00"
|
||||
dropwizard_tags_path = "tags"
|
||||
## tag paths per tag are supported too, eg.

# tag1 = "tags.tag1"
|

# tag2 = "tags.tag2"

# Output Data Formats

# Telegraf Output Data Formats
|
||||
|
||||
In addition to output specific data formats, Telegraf supports a set of
|
||||
standard data formats that may be selected from when configuring many output
|
||||
plugins.
|
||||
Telegraf metrics, like InfluxDB
|
||||
[points](https://docs.influxdata.com/influxdb/v0.10/write_protocols/line/),
|
||||
are a combination of four basic parts:
|
||||
|
||||
1. [InfluxDB Line Protocol](#influx)
|
||||
1. [JSON](#json)
|
||||
1. [Graphite](#graphite)
|
||||
1. Measurement Name
|
||||
1. Tags
|
||||
1. Fields
|
||||
1. Timestamp
|
||||
|
||||
In InfluxDB line protocol, these 4 parts are easily defined in textual form:
|
||||
|
||||
```
|
||||
measurement_name[,tag1=val1,...] field1=val1[,field2=val2,...] [timestamp]
|
||||
```
|
||||
|
||||
For Telegraf outputs that write textual data (such as `kafka`, `mqtt`, and `file`),
|
||||
InfluxDB line protocol was originally the only available output format. But now
|
||||
we are normalizing telegraf metric "serializers" into a
|
||||
[plugin-like interface](https://github.com/influxdata/telegraf/tree/master/plugins/serializers)
|
||||
across all output plugins that can support it.
|
||||
You will be able to identify a plugin that supports different data formats
|
||||
by the presence of a `data_format`
|
||||
config option, for example, in the `file` output plugin:
|
||||
|
||||
You will be able to identify the plugins with support by the presence of a
|
||||
`data_format` config option, for example, in the `file` output plugin:

||||

|

||||

||||
## Influx
|
||||
Each data_format has an additional set of configuration options available, which
|
||||
I'll go over below.
|
||||
|
||||
The `influx` data format outputs metrics using
|
||||
[InfluxDB Line Protocol](https://docs.influxdata.com/influxdb/latest/write_protocols/line_protocol_tutorial/).
|
||||
This is the recommended format unless another format is required for
|
||||
interoperability.
|
||||
## Influx:
|
||||
|
||||
There are no additional configuration options for InfluxDB line-protocol. The
|
||||
metrics are serialized directly into InfluxDB line-protocol.
|
||||
|
||||
#### Influx Configuration:

|
||||
data_format = "influx"
|
||||
|
||||
## Maximum line length in bytes. Useful only for debugging.
|
||||
# influx_max_line_bytes = 0
|
||||
|
||||
## When true, fields will be output in ascending lexical order. Enabling
|
||||
## this option will result in decreased performance and is only recommended
|
||||
## when you need predictable ordering while debugging.
|
||||
# influx_sort_fields = false
|
||||
|
||||
## When true, Telegraf will output unsigned integers as unsigned values,
|
||||
## i.e.: `42u`. You will need a version of InfluxDB supporting unsigned
|
||||
## integer values. Enabling this option will result in field type errors if
|
||||
## existing data has been written.
|
||||
# influx_uint_support = false
|
||||
```
|
||||
|
||||
## Graphite
|
||||
## Graphite:
|
||||
|
||||
The Graphite data format is translated from Telegraf Metrics using either the
|
||||
template pattern or tag support method. You can select between the two
|
||||
methods using the [`graphite_tag_support`](#graphite-tag-support) option. When set, the tag support
|
||||
method is used, otherwise the [`template` pattern](#template-pattern) is used.
|
||||
|
||||
#### Template Pattern
|
||||
|
||||
The `template` option describes how Telegraf traslates metrics into _dot_
|
||||
buckets. The default template is:
|
||||
The Graphite data format translates Telegraf metrics into _dot_ buckets.
|
||||
The format is:
|
||||
|
||||
```
|
||||
template = "host.tags.measurement.field"
|
||||
[prefix].[host tag].[all tags (alphabetical)].[measurement name].[field name] value timestamp
|
||||
```
|
||||
|
||||
In the above template, we have four parts:
|
||||
|
||||
1. _host_ is a tag key. This can be any tag key that is in the Telegraf
|
||||
metric(s). If the key doesn't exist, it will be ignored. If it does exist, the
|
||||
tag value will be filled in.
|
||||
1. _tags_ is a special keyword that outputs all remaining tag values, separated
|
||||
by dots and in alphabetical order (by tag key). These will be filled after all
|
||||
tag keys are filled.
|
||||
1. _measurement_ is a special keyword that outputs the measurement name.
|
||||
1. _field_ is a special keyword that outputs the field name.
|
||||
|
||||
**Example Conversion**:
|
||||
Which means the following influx metric -> graphite conversion would happen:
|
||||
|
||||
```
|
||||
cpu,cpu=cpu-total,dc=us-east-1,host=tars usage_idle=98.09,usage_user=0.89 1455320660004257758

||||
tars.cpu-total.us-east-1.cpu.usage_idle 98.09 1455320690
|
||||
```
|
||||
|
||||
Fields with string values will be skipped. Boolean fields will be converted
|
||||
to 1 (true) or 0 (false).
|
||||
`prefix` is a configuration option when using the graphite output data format.
|
||||
|
||||
#### Graphite Tag Support
|
||||
|
||||
When the `graphite_tag_support` option is enabled, the template pattern is not
|
||||
used. Instead, tags are encoded using
|
||||
[Graphite tag support](http://graphite.readthedocs.io/en/latest/tags.html)
|
||||
added in Graphite 1.1. The `metric_path` is a combination of the optional
|
||||
`prefix` option, measurement name, and field name.
|
||||
|
||||
The tag `name` is reserved by Graphite, any conflicting tags and will be encoded as `_name`.
|
||||
|
||||
**Example Conversion**:
|
||||
```
|
||||
cpu,cpu=cpu-total,dc=us-east-1,host=tars usage_idle=98.09,usage_user=0.89 1455320660004257758

||||
```
|
||||
|
||||
## JSON
|
||||
|
||||
The JSON output data format output for a single metric is in the
|
||||
form:
|
||||
```json
|
||||
{
|
||||
"fields": {
|
||||
"field_1": 30,
|
||||
"field_2": 4,
|
||||
"field_N": 59,
|
||||
"n_images": 660
|
||||
},
|
||||
"name": "docker",
|
||||
"tags": {
|
||||
"host": "raynor"
|
||||
},
|
||||
"timestamp": 1458229140
|
||||
}
|
||||
```
|
||||
|
||||
When an output plugin needs to emit multiple metrics at one time, it may use
|
||||
the batch format. The use of batch format is determined by the plugin,
|
||||
reference the documentation for the specific plugin.
|
||||

# Frequently Asked Questions
|
||||
|
||||
### Q: How can I monitor the Docker Engine Host from within a container?
|
||||
|
||||
You will need to setup several volume mounts as well as some environment
|
||||
variables:
|
||||
```
|
||||
docker run --name telegraf
|
||||
-v /:/hostfs:ro
|
||||
-v /etc:/hostfs/etc:ro
|
||||
-v /proc:/hostfs/proc:ro
|
||||
-v /sys:/hostfs/sys:ro
|
||||
-v /var/run/utmp:/var/run/utmp:ro
|
||||
-e HOST_ETC=/hostfs/etc
|
||||
-e HOST_PROC=/hostfs/proc
|
||||
-e HOST_SYS=/hostfs/sys
|
||||
-e HOST_MOUNT_PREFIX=/hostfs
|
||||
telegraf
|
||||
```
|
||||
|
||||
|
||||
### Q: Why do I get a "no such host" error resolving hostnames that other
|
||||
programs can resolve?
|
||||
|
||||
Go uses a pure Go resolver by default for [name resolution](https://golang.org/pkg/net/#hdr-Name_Resolution).
|
||||
This resolver behaves differently than the C library functions but is more
|
||||
efficient when used with the Go runtime.
|
||||
|
||||
If you encounter problems or want to use more advanced name resolution methods
|
||||
that are unsupported by the pure Go resolver, you can switch to the cgo
|
||||
resolver.
|
||||
|
||||
If running manually set:
|
||||
```
|
||||
export GODEBUG=netdns=cgo
|
||||
```
|
||||
|
||||
If running as a service add the environment variable to `/etc/default/telegraf`:
|
||||
```
|
||||
GODEBUG=netdns=cgo
|
||||
```
|
||||
|
||||
### Q: When will the next version be released?
|
||||
|
||||
The latest release date estimate can be viewed on the
|
||||
[milestones](https://github.com/influxdata/telegraf/milestones) page.

# Telegraf profiling
|
||||
|
||||
Telegraf uses the standard package `net/http/pprof`. This package serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool.
|
||||
|
||||
By default, the profiling is turned off.
|
||||
|
||||
To enable profiling you need to specify address to config parameter `pprof-addr`, for example:
|
||||
|
||||
```
|
||||
telegraf --config telegraf.conf --pprof-addr localhost:6060
|
||||
```
|
||||
|
||||
There are several paths to get different profiling information:
|
||||
|
||||
To look at the heap profile:
|
||||
|
||||
`go tool pprof http://localhost:6060/debug/pprof/heap`
|
||||
|
||||
or to look at a 30-second CPU profile:
|
||||
|
||||
`go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30`
|
||||
|
||||
To view all available profiles, open `http://localhost:6060/debug/pprof/` in your browser.

# Running Telegraf as a Windows Service
|
||||
|
||||
Telegraf natively supports running as a Windows Service. Outlined below is are
|
||||
the general steps to set it up.
|
||||
|
||||
1. Obtain the telegraf windows distribution
|
||||
2. Create the directory `C:\Program Files\Telegraf` (if you install in a different
|
||||
location simply specify the `--config` parameter with the desired location)
|
||||
3. Place the telegraf.exe and the telegraf.conf config file into `C:\Program Files\Telegraf`
|
||||
4. To install the service into the Windows Service Manager, run the following in PowerShell as an administrator (If necessary, you can wrap any spaces in the file paths in double quotes ""):
|
||||
|
||||
```
|
||||
> C:\"Program Files"\Telegraf\telegraf.exe --service install
|
||||
```
|
||||
|
||||
5. Edit the configuration file to meet your needs
|
||||
6. To check that it works, run:
|
||||
|
||||
```
|
||||
> C:\"Program Files"\Telegraf\telegraf.exe --config C:\"Program Files"\Telegraf\telegraf.conf --test
|
||||
```
|
||||
|
||||
7. To start collecting data, run:
|
||||
|
||||
```
|
||||
> net start telegraf
|
||||
```
|
||||
|
||||
## Config Directory
|
||||
|
||||
You can also specify a `--config-directory` for the service to use:
|
||||
1. Create a directory for config snippets: `C:\Program Files\Telegraf\telegraf.d`
|
||||
2. Include the `--config-directory` option when registering the service:
|
||||
```
|
||||
> C:\"Program Files"\Telegraf\telegraf.exe --service install --config C:\"Program Files"\Telegraf\telegraf.conf --config-directory C:\"Program Files"\Telegraf\telegraf.d
|
||||
```
|
||||
|
||||
## Other supported operations
|
||||
|
||||
Telegraf can manage its own service through the --service flag:
|
||||
|
||||
| Command | Effect |
|
||||
|------------------------------------|-------------------------------|
|
||||
| `telegraf.exe --service install` | Install telegraf as a service |
|
||||
| `telegraf.exe --service uninstall` | Remove the telegraf service |
|
||||
| `telegraf.exe --service start` | Start the telegraf service |
|
||||
| `telegraf.exe --service stop` | Stop the telegraf service |
|
||||
|
||||
Troubleshooting common error #1067
|
||||
|
||||
When installing as service in Windows, always double check to specify full path of the config file, otherwise windows service will fail to start
|
||||
|
||||
--config C:\"Program Files"\Telegraf\telegraf.conf

Usage:
|
||||
|
||||
telegraf [commands|flags]
|
||||
|
||||
The commands & flags are:
|
||||
|
||||
config print out full sample configuration to stdout
|
||||
version print the version to stdout
|
||||
|
||||
--config <file> configuration file to load
|
||||
--test gather metrics once, print them to stdout, and exit
|
||||
--config-directory directory containing additional *.conf files
|
||||
--input-filter filter the input plugins to enable, separator is :
|
||||
--output-filter filter the output plugins to enable, separator is :
|
||||
--usage print usage for a plugin, ie, 'telegraf --usage mysql'
|
||||
--debug print metrics as they're generated to stdout
|
||||
--pprof-addr pprof address to listen on, format: localhost:6060 or :6060
|
||||
--quiet run in quiet mode
|
||||
|
||||
Examples:
|
||||
|
||||
# generate a telegraf config file:
|

telegraf config > telegraf.conf
|
||||
|
||||
# generate config with only cpu input & influxdb output plugins defined
|
||||
telegraf --input-filter cpu --output-filter influxdb config
|
||||
|
||||
# run a single telegraf collection, outputing metrics to stdout
|
||||
telegraf --config telegraf.conf --test
|
||||
|
||||
# run telegraf with all plugins defined in config file
|

const Usage = `Telegraf, The plugin-driven server agent for collecting and reporting metrics.
|
||||
|
||||
Usage:
|
||||
|
||||
telegraf [commands|flags]
|
||||
|
||||
The commands & flags are:
|
||||
|
||||
config print out full sample configuration to stdout
|
||||
version print the version to stdout
|
||||
|
||||
--config <file> configuration file to load
|
||||
--test gather metrics once, print them to stdout, and exit
|
||||
--config-directory directory containing additional *.conf files
|
||||
--input-filter filter the input plugins to enable, separator is :
|
||||
--output-filter filter the output plugins to enable, separator is :
|
||||
--usage print usage for a plugin, ie, 'telegraf --usage mysql'
|
||||
--debug print metrics as they're generated to stdout
|
||||
--pprof-addr pprof address to listen on, format: localhost:6060 or :6060
|
||||
--quiet run in quiet mode
|
||||
|
||||
--console run as console application
|
||||
--service operate on service, one of: install, uninstall, start, stop
|
||||
|
||||
Examples:
|
||||
|
||||
# generate a telegraf config file:
|
||||
telegraf config > telegraf.conf
|
||||
|
||||
# generate config with only cpu input & influxdb output plugins defined
|
||||
telegraf --input-filter cpu --output-filter influxdb config
|
||||
|
||||
# run a single telegraf collection, outputing metrics to stdout
|
||||
telegraf --config telegraf.conf --test
|
||||
|
||||
# run telegraf with all plugins defined in config file
|
||||
telegraf --config telegraf.conf
|

# BasicStats Aggregator Plugin
|
||||
|
||||
The BasicStats aggregator plugin give us count,max,min,mean,sum,s2(variance), stdev for a set of values,
|
||||
emitting the aggregate every `period` seconds.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Keep the aggregate basicstats of each metric passing through.
|
||||
[[aggregators.basicstats]]
|
||||
|
||||
## General Aggregator Arguments:
|
||||
|
||||
## The period on which to flush & clear the aggregator.
|
||||
period = "30s"
|
||||
|
||||
## If true, the original metric will be dropped by the
|
||||
## aggregator and will not get sent to the output plugins.
|
||||
drop_original = false
|
||||
|
||||
## BasicStats Arguments:
|
||||
|
||||
## Configures which basic stats to push as fields
|
||||
stats = ["count","min","max","mean","stdev","s2","sum"]
|
||||
```
|
||||
|
||||
- stats
|
||||
- If not specified, then `count`, `min`, `max`, `mean`, `stdev`, and `s2` are aggregated and pushed as fields. `sum` is not aggregated by default to maintain backwards compatibility.
|
||||
- If empty array, no stats are aggregated
|
||||
|
||||
### Measurements & Fields:
|
||||
|
||||
- measurement1
|
||||
- field1_count
|
||||
- field1_max
|
||||
- field1_min
|
||||
- field1_mean
|
||||
- field1_sum
|
||||
- field1_s2 (variance)
|
||||
- field1_stdev (standard deviation)
|
||||
|
||||
### Tags:
|
||||
|
||||
No tags are applied by this aggregator.
|
||||
|
||||
### Example Output:
|
||||
|
||||
```
|
||||

# Histogram Aggregator Plugin
|
||||
|
||||
The histogram aggregator plugin creates histograms containing the counts of
|
||||
field values within a range.
|
||||
|
||||
Values added to a bucket are also added to the larger buckets in the
|
||||
distribution. This creates a [cumulative histogram](https://en.wikipedia.org/wiki/Histogram#/media/File:Cumulative_vs_normal_histogram.svg).
|
||||
|
||||
Like other Telegraf aggregators, the metric is emitted every `period` seconds.
|
||||
Bucket counts however are not reset between periods and will be non-strictly
|
||||
increasing while Telegraf is running.
|
||||
|
||||
#### Design
|
||||
|
||||
Each metric is passed to the aggregator and this aggregator searches
|
||||
histogram buckets for those fields, which have been specified in the
|
||||
config. If buckets are found, the aggregator will increment +1 to the appropriate
|
||||
bucket otherwise it will be added to the `+Inf` bucket. Every `period`
|
||||
seconds this data will be forwarded to the outputs.
|
||||
|
||||
The algorithm of hit counting to buckets was implemented on the base
|
||||
of the algorithm which is implemented in the Prometheus
|
||||
[client](https://github.com/prometheus/client_golang/blob/master/prometheus/histogram.go).
|
||||
|
||||
### Configuration
|
||||
|
||||
```toml
|
||||
# Configuration for aggregate histogram metrics
|
||||
[[aggregators.histogram]]
|
||||
## The period in which to flush the aggregator.
|
||||
period = "30s"
|
||||
|
||||
## If true, the original metric will be dropped by the
|
||||
## aggregator and will not get sent to the output plugins.
|
||||
drop_original = false
|
||||
|
||||
## Example config that aggregates all fields of the metric.
|
||||
# [[aggregators.histogram.config]]
|
||||
# ## The set of buckets.
|
||||
# buckets = [0.0, 15.6, 34.5, 49.1, 71.5, 80.5, 94.5, 100.0]
|
||||
# ## The name of metric.
|
||||
# measurement_name = "cpu"
|
||||
|
||||
## Example config that aggregates only specific fields of the metric.
|
||||
# [[aggregators.histogram.config]]
|
||||
# ## The set of buckets.
|
||||
# buckets = [0.0, 10.0, 20.0, 30.0, 40.0, 50.0, 60.0, 70.0, 80.0, 90.0, 100.0]
|
||||
# ## The name of metric.
|
||||
# measurement_name = "diskio"
|
||||
# ## The concrete fields of metric
|
||||
# fields = ["io_time", "read_time", "write_time"]
|
||||
```
|
||||
|
||||
The user is responsible for defining the bounds of the histogram bucket as
|
||||
well as the measurement name and fields to aggregate.
|
||||
|
||||
Each histogram config section must contain a `buckets` and `measurement_name`
|
||||
option. Optionally, if `fields` is set only the fields listed will be
|
||||
aggregated. If `fields` is not set all fields are aggregated.
|
||||
|
||||
The `buckets` option contains a list of floats which specify the bucket
|
||||
boundaries. Each float value defines the inclusive upper bound of the bucket.
|
||||
The `+Inf` bucket is added automatically and does not need to be defined.
|
||||
|
||||
### Measurements & Fields:
|
||||
|
||||
The postfix `bucket` will be added to each field key.
|
||||
|
||||
- measurement1
|
||||
- field1_bucket
|
||||
- field2_bucket
|
||||
|
||||
### Tags:
|
||||
|
||||
All measurements are given the tag `le`. This tag has the border value of
|
||||
bucket. It means that the metric value is less than or equal to the value of
|
||||
this tag. For example, let assume that we have the metric value 10 and the
|
||||
following buckets: [5, 10, 30, 70, 100]. Then the tag `le` will have the value
|
||||
10, because the metrics value is passed into bucket with right border value
|
||||
`10`.
|
||||
|
||||

# MinMax Aggregator Plugin
|
||||
|
||||
The minmax aggregator plugin aggregates min & max values of each field it sees,
|
||||
emitting the aggrate every `period` seconds.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Keep the aggregate min/max of each metric passing through.
|
||||
[[aggregators.minmax]]
|
||||
## General Aggregator Arguments:
|
||||
## The period on which to flush & clear the aggregator.
|
||||
period = "30s"
|
||||
## If true, the original metric will be dropped by the
|
||||
## aggregator and will not get sent to the output plugins.
|
||||
drop_original = false
|
||||
```
|
||||
|
||||
### Measurements & Fields:

# ValueCounter Aggregator Plugin
|
||||
|
||||
The valuecounter plugin counts the occurrence of values in fields and emits the
|
||||
counter once every 'period' seconds.
|
||||
|
||||
A use case for the valuecounter plugin is when you are processing a HTTP access
|
||||
log (with the logparser input) and want to count the HTTP status codes.
|
||||
|
||||
The fields which will be counted must be configured with the `fields`
|
||||
configuration directive. When no `fields` is provided the plugin will not count
|
||||
any fields. The results are emitted in fields in the format:
|
||||
`originalfieldname_fieldvalue = count`.
|
||||
|
||||
Valuecounter only works on fields of the type int, bool or string. Float fields
|
||||
are being dropped to prevent the creating of too many fields.
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
[[aggregators.valuecounter]]
|
||||
## General Aggregator Arguments:
|
||||
## The period on which to flush & clear the aggregator.
|
||||
period = "30s"
|
||||
## If true, the original metric will be dropped by the
|
||||
## aggregator and will not get sent to the output plugins.
|
||||
drop_original = false
|
||||
## The fields for which the values will be counted
|
||||
fields = ["status"]
|
||||
```
|
||||
|
||||
### Measurements & Fields:

# Example Input Plugin
|
||||
|
||||
The example plugin gathers metrics about example things. This description
|
||||
explains at a high level what the plugin does and provides links to where
|
||||
additional information can be found.
|
||||
The example plugin gathers metrics about example things
|
||||
|
||||
### Configuration:
|
||||
|
||||
This section contains the default TOML to configure the plugin. You can
|
||||
generate it using `telegraf --usage <plugin-name>`.
|
||||
|
||||
```toml
|
||||
# Description
|
||||
[[inputs.example]]
|
||||
example_option = "example_value"
|
||||
# SampleConfig
|
||||
```
|
||||
|
||||
### Metrics:
|
||||
### Measurements & Fields:
|
||||
|
||||
Here you should add an optional description and links to where the user can
|
||||
get more information about the measurements.
|
||||
|
||||
If the output is determined dynamically based on the input source, or there
|
||||
are more metrics than can reasonably be listed, describe how the input is
|
||||
mapped to the output.
|
||||
<optional description>
|
||||
|
||||
- measurement1
|
||||
- tags:
|
||||
- tag1 (optional description)
|
||||
- tag2
|
||||
- fields:
|
||||
- field1 (type, unit)
|
||||
- field2 (float, percent)
|
||||
|
||||
- measurement2
|
||||
- tags:
|
||||
- tag3
|
||||
- fields:
|
||||
- field3 (integer, bytes)
|
||||
|
||||
### Sample Queries:
|
||||
### Tags:
|
||||
|
||||
This section should contain some useful InfluxDB queries that can be used to
|
||||
get started with the plugin or to generate dashboards. For each query listed,
|
||||
describe at a high level what data is returned.
|
||||
|
||||
Get the max, mean, and min for the measurement in the last hour:
|
||||
```
|
||||
SELECT max(field1), mean(field1), min(field1) FROM measurement1 WHERE tag1=bar AND time > now() - 1h GROUP BY tag
|
||||
```
|
||||
- All measurements have the following tags:
|
||||
- tag1 (optional description)
|
||||
- tag2
|
||||
- measurement2 has the following tags:
|
||||
- tag3
|
||||
|
||||
### Example Output:
|
||||
|
||||
This section shows example output in Line Protocol format. You can often use
|
||||
`telegraf --input-filter <plugin-name> --test` or use the `file` output to get
|
||||
this information.
|
||||
Give an example `-test` output here
|
||||
|
||||
```
|
||||
$ ./telegraf -config telegraf.conf -input-filter example -test
|
||||
measurement1,tag1=foo,tag2=bar field1=1i,field2=2.1 1453831884664956455

# AMQP Consumer Input Plugin
|
||||
|
||||
This plugin provides a consumer for use with AMQP 0-9-1, a promenent implementation of this protocol being [RabbitMQ](https://www.rabbitmq.com/).
|
||||
|
||||
Metrics are read from a topic exchange using the configured queue and binding_key.
|
||||
|
||||
Message payload should be formatted in one of the [Telegraf Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
|
||||
|
||||
For an introduction to AMQP see:
|
||||
- https://www.rabbitmq.com/tutorials/amqp-concepts.html
|
||||
- https://www.rabbitmq.com/getstarted.html
|
||||
|
||||
The following defaults are known to work with RabbitMQ:
|
||||
|
||||
```toml
|
||||
# AMQP consumer plugin
|
||||
[[inputs.amqp_consumer]]
|
||||
## Broker to consume from.
|
||||
## deprecated in 1.7; use the brokers option
|
||||
# url = "amqp://localhost:5672/influxdb"
|
||||
|
||||
## Brokers to consume from. If multiple brokers are specified a random broker
|
||||
## will be selected anytime a connection is established. This can be
|
||||
## helpful for load balancing when not using a dedicated load balancer.
|
||||
brokers = ["amqp://localhost:5672/influxdb"]
|
||||
|
||||
## Authentication credentials for the PLAIN auth_method.
|
||||
# username = ""
|
||||
# password = ""
|
||||
|
||||
## Exchange to declare and consume from.
|
||||
exchange = "telegraf"
|
||||
|
||||
## Exchange type; common types are "direct", "fanout", "topic", "header", "x-consistent-hash".
|
||||
# exchange_type = "topic"
|
||||
|
||||
## If true, exchange will be passively declared.
|
||||
# exchange_passive = false
|
||||
|
||||
## Exchange durability can be either "transient" or "durable".
|
||||
# exchange_durability = "durable"
|
||||
|
||||
## Additional exchange arguments.
|
||||
# exchange_arguments = { }
|
||||
# exchange_arguments = {"hash_propery" = "timestamp"}
|
||||
|
||||
## AMQP queue name
|
||||
queue = "telegraf"
|
||||
## Binding Key
|
||||
binding_key = "#"
|
||||
|
||||
## Maximum number of messages server should give to the worker.
|
||||
# prefetch_count = 50
|
||||
|
||||
## Auth method. PLAIN and EXTERNAL are supported
|
||||
## Using EXTERNAL requires enabling the rabbitmq_auth_mechanism_ssl plugin as
|
||||
## described here: https://www.rabbitmq.com/plugins.html
|
||||
# auth_method = "PLAIN"
|
||||
|
||||
## Optional TLS Config
|
||||
# tls_ca = "/etc/telegraf/ca.pem"
|
||||
# tls_cert = "/etc/telegraf/cert.pem"
|
||||
# tls_key = "/etc/telegraf/key.pem"
|
||||
## Use TLS but skip chain & host verification
|
||||
# insecure_skip_verify = false
|
||||
|
||||
## Data format to consume.
|
||||
## Each data format has its own unique set of configuration options, read
|
||||
## more about them here:
|
||||
## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
|
||||
data_format = "influx"
|
||||
