## v1.2 [unreleased]

||||
## v1.1 [unreleased]
|
||||
|
||||
### Release Notes
|
||||
|
||||
- The StatsD plugin will now default all "delete_" config options to "true". This
|
||||
will change te default behavior for users who were not specifying these parameters
|
||||
in their config file.
|
||||
|
||||
- The StatsD plugin will also no longer save it's state on a service reload.
|
||||
Essentially we have reverted PR [#887](https://github.com/influxdata/telegraf/pull/887).
|
||||
The reason for this is that saving the state in a global variable is not
|
||||
thread-safe (see [#1975](https://github.com/influxdata/telegraf/issues/1975) & [#2102](https://github.com/influxdata/telegraf/issues/2102)),
|
||||
and this creates issues if users want to define multiple instances
|
||||
of the statsd plugin. Saving state on reload may be considered in the future,
|
||||
but this would need to be implemented at a higher level and applied to all
|
||||
plugins, not just statsd.
|
||||
|
||||

### Release Notes
|
||||
|
||||
- Telegraf now supports two new types of plugins: processors & aggregators.
|
||||
|
||||
- On systemd Telegraf will no longer redirect it's stdout to /var/log/telegraf/telegraf.log.

||||
On most systems, the logs will be directed to the systemd journal and can be
|
||||
accessed by `journalctl -u telegraf.service`. Consult the systemd journal
|
||||
documentation for configuring journald. There is also a [`logfile` config option](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf#L70)
|
||||
available in 1.1, which will allow users to easily configure telegraf to
|
||||
continue sending logs to /var/log/telegraf/telegraf.log.

This section is for developers who want to create a new processor plugin.
|
||||
|
||||
### Processor Plugin Guidelines
|
||||
|
||||
* A processor must conform to the [`telegraf.Processor`](https://godoc.org/github.com/influxdata/telegraf#Processor) interface.
|
||||
* Processors should call `processors.Add` in their `init` function to register themselves.

||||
processor can be configured. This is include in `telegraf -sample-config`.
|
||||
* The `Description` function should say in one line what this processor does.
|
||||

## 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 -sample-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.
|
||||
|
||||

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
|
||||
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
|
||||
3. [Aggregator Plugins](#aggregator-plugins) create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
|
||||
4. [Output Plugins](#output-plugins) write metrics to various destinations
|
||||
|
||||
For more information on Processor and Aggregator plugins please [read this](./docs/AGGREGATORS_AND_PROCESSORS.md).

# 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.
|
||||
|
||||
**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)

## Generating a Configuration File

||||
|
||||
A default Telegraf config file can be auto-generated by telegraf:
|
||||
A default Telegraf config file can be generated using the -sample-config flag:
|
||||

telegraf -sample-config > telegraf.conf

## 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)

## `[global_tags]` Configuration
|

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

# 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:
|
||||
|
||||
- measurement1
|
||||
- field1_max
|
||||
- field1_min
|
||||
|
||||
### Tags:
|
||||
|
||||
No tags are applied by this aggregator.
|
||||
|
||||
### Example Output:
|
||||
|
||||
```
|
||||

# HAproxy Input Plugin
|
||||
|
||||
[HAproxy](http://www.haproxy.org/) input plugin gathers metrics directly from any running HAproxy instance. It can do so by using CSV generated by HAproxy status page or from admin socket(s).
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# SampleConfig
|
||||
[[inputs.haproxy]]
|
||||
servers = ["http://1.2.3.4/haproxy?stats", "/var/run/haproxy*.sock"]
|
||||
```
|
||||
|
||||
Server addresses need to explicitly start with 'http' if you wish to use HAproxy status page. Otherwise, address will be assumed to be an UNIX socket and protocol (if present) will be discarded.
|
||||
|
||||
Following examples will all resolve to the same socket:
|
||||
```
|
||||
socket:/var/run/haproxy.sock
|
||||
unix:/var/run/haproxy.sock
|
||||
foo:/var/run/haproxy.sock
|
||||
/var/run/haproxy.sock
|
||||
```
|
||||
|
||||
When using socket names, wildcard expansion is supported so plugin can gather stats from multiple sockets at once.
|
||||
|
||||
If no servers are specified, then the default address of `http://127.0.0.1:1936/haproxy?stats` will be used.
|
||||
|
||||
### Measurements & Fields:
|
||||
|
||||
Plugin will gather measurements outlined in [HAproxy CSV format documentation](https://cbonte.github.io/haproxy-dconv/1.5/configuration.html#9.1).
|
||||
|
||||
### Tags:
|
||||
|
||||
- All measurements have the following tags:
|
||||
- server - address of server data is gathered from
|
||||
- proxy - proxy name as reported in `pxname`
|
||||
- sv - service name as reported in `svname`
