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.
**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.

# Running Telegraf as a Windows Service
If you have tried to install Go binaries as Windows Services with the **sc.exe**
tool you may have seen that the service errors and stops running after a while.
**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a
[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
that were not specifically designed to run only in Windows platforms.
## NSSM Installation via Chocolatey
You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/)
with these commands
```powershell
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
choco install -y nssm
```
## Installing Telegraf as a Windows Service with NSSM
You can download the latest Telegraf Windows binaries (still Experimental at
the moment) from [the Telegraf Github repo](https://github.com/influxdata/telegraf).
Then you can create a C:\telegraf folder, unzip the binary there and modify the
**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
Once you have NSSM installed in your system, the process is quite straightforward.
You only need to type this command in your Windows shell
```powershell
nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
```
And now your service will be installed in Windows and you will be able to start and
stop it gracefully

# Amazon CloudWatch Statistics Input
This plugin will pull Metric Statistics from Amazon CloudWatch.
### Amazon Authentication
This plugin uses a credential chain for Authentication with the CloudWatch
API endpoint. In the following order the plugin will attempt to authenticate.
1. [IAMS Role](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html)
2. [Environment Variables](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#environment-variables)
3. [Shared Credentials](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#shared-credentials-file)
### Configuration:
```toml
[[inputs.cloudwatch]]
## Amazon Region (required)
region = 'us-east-1'
## Requested CloudWatch aggregation Period (required - must be a multiple of 60s)
period = '1m'
## Collection Delay (required - must account for metrics availability via CloudWatch API)
delay = '1m'
## Override global run interval (optional - defaults to global interval)
## Recomended: use metric 'interval' that is a multiple of 'period' to avoid
## gaps or overlap in pulled data
interval = '1m'
## Metric Statistic Namespace (required)
namespace = 'AWS/ELB'
## Metrics to Pull (optional)
## Defaults to all Metrics in Namespace if nothing is provided
## Refreshes Namespace available metrics every 1h
[[inputs.cloudwatch.metrics]]
names = ['Latency', 'RequestCount']
## Dimension filters for Metric (optional)
[[inputs.cloudwatch.metrics.dimensions]]
name = 'LoadBalancerName'
value = 'p-example'
```
#### Requirements and Terminology
Plugin Configuration utilizes [CloudWatch concepts](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html) and access pattern to allow monitoring of any CloudWatch Metric.
- `region` must be a valid AWS [Region](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#CloudWatchRegions) value
- `period` must be a valid CloudWatch [Period](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#CloudWatchPeriods) value
- `namespace` must be a valid CloudWatch [Namespace](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Namespace) value
- `names` must be valid CloudWatch [Metric](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Metric) names
- `dimensions` must be valid CloudWatch [Dimension](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Dimension) name/value pairs
#### Restrictions and Limitations
- CloudWatch metrics are not available instantly via the CloudWatch API. You should adjust your collection `delay` to account for this lag in metrics availability based on your [monitoring subscription level](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-cloudwatch-new.html)
- CloudWatch API usage incurs cost - see [GetMetricStatistics Pricing](https://aws.amazon.com/cloudwatch/pricing/)
### Measurements & Fields:
Each CloudWatch Namespace monitored records a measurement with fields for each available Metric Statistic
Namespace and Metrics are represented in [snake case](https://en.wikipedia.org/wiki/Snake_case)
- cloudwatch_{namespace}
- {metric}_sum (metric Sum value)
- {metric}_average (metric Average value)
- {metric}_minimum (metric Minimum value)
- {metric}_maximum (metric Maximum value)
- {metric}_sample_count (metric SampleCount value)
### Tags:
Each measurement is tagged with the following identifiers to uniquely identify the associated metric
Tag Dimension names are represented in [snake case](https://en.wikipedia.org/wiki/Snake_case)
- All measurements have the following tags:
- region (CloudWatch Region)
- unit (CloudWatch Metric Unit)
- {dimension-name} (Cloudwatch Dimension value - one for each metric dimension)
### Example Output:
```
$ ./telegraf -config telegraf.conf -input-filter cloudwatch -test
> cloudwatch_aws_elb,load_balancer_name=p-example,region=us-east-1,unit=seconds latency_average=0.004810798017284538,latency_maximum=0.1100282669067383,latency_minimum=0.0006084442138671875,latency_sample_count=4029,latency_sum=19.382705211639404 1459542420000000000

## specify servers via a url matching:
## [protocol://][:password]@address[:port]
## e.g.
## http://couchbase-0.example.com/
## http://admin:secret@couchbase-0.example.com:8091/
##
## If no servers are specified, then localhost is used as the host.
## If no protocol is specifed, HTTP is used.
## If no port is specified, 8091 is used.

- hostname: Couchbase's name for the node and port, e.g., `172.16.10.187:8091`
Fields:
- memory_free (unit: bytes, example: 23181365248.0)
- memory_total (unit: bytes, example: 64424656896.0)
### couchbase_bucket
Tags:
- cluster: whatever you called it in `servers` in the configuration, e.g.: `http://couchbase-0.example.com/`)
- bucket: the name of the couchbase bucket, e.g., `blastro-df`
Fields:
- quota_percent_used (unit: percent, example: 68.85424936294555)
- ops_per_sec (unit: count, example: 5686.789686789687)
- disk_fetches (unit: count, example: 0.0)

# Telegraf ipmi plugin
Get bare metal metrics using the command line utility `ipmitool`
see ipmitool(https://sourceforge.net/projects/ipmitool/files/ipmitool/)
The plugin will use the following command to collect remote host sensor stats:
ipmitool -I lan -H 192.168.1.1 -U USERID -P PASSW0RD sdr
## Measurements
- ipmi_sensor:
* Tags: `name`, `server`, `unit`
* Fields:
- status
- value
## Configuration
```toml
[[inputs.ipmi]]
## specify servers via a url matching:
## [username[:password]@][protocol[(address)]]
## e.g.
## root:passwd@lan(127.0.0.1)
##
servers = ["USERID:PASSW0RD@lan(10.20.2.203)"]
```
## Output
```

# Telegraf plugin: Jolokia
#### Plugin arguments:
- **context** string: Context root used of jolokia url
- **servers** []Server: List of servers
+ **name** string: Server's logical name
+ **host** string: Server's ip address or hostname
+ **port** string: Server's listening port
- **metrics** []Metric
+ **name** string: Name of the measure
+ **jmx** string: Jmx path that identifies mbeans attributes
+ **pass** []string: Attributes to retain when collecting values
+ **drop** []string: Attributes to drop when collecting values
#### Configuration
```toml
[[inputs.jolokia]]
## This is the context root used to compose the jolokia url
context = "/jolokia/read"
## List of servers exposing jolokia read service
[[inputs.jolokia.servers]]
name = "stable"
host = "192.168.103.2"
port = "8180"
# username = "myuser"
# password = "mypassword"
## List of metrics collected on above servers
## Each metric consists in a name, a jmx path and either
## a pass or drop slice attribute.
## This collect all heap memory usage metrics.
[[inputs.jolokia.metrics]]
name = "heap_memory_usage"
jmx = "/java.lang:type=Memory/HeapMemoryUsage"
```
#### Description
@ -21,31 +33,3 @@ See: https://jolokia.org/
# Measurements:
Jolokia plugin produces one measure for each metric configured, adding Server's `name`, `host` and `port` as tags.
Given a configuration like:
```ini
[jolokia]
[[jolokia.servers]]
name = "as-service-1"
host = "127.0.0.1"
port = "8080"
[[jolokia.servers]]
name = "as-service-2"
host = "127.0.0.1"
port = "8180"
[[jolokia.metrics]]
name = "heap_memory_usage"
jmx = "/java.lang:type=Memory/HeapMemoryUsage"
pass = ["used", "max"]
```
The collected metrics will be:
```
jolokia_heap_memory_usage name=as-service-1,host=127.0.0.1,port=8080 used=xxx,max=yyy
jolokia_heap_memory_usage name=as-service-2,host=127.0.0.1,port=8180 used=vvv,max=zzz

# Telegraf Plugin: Nginx
### Configuration:
```
# Read Nginx's basic status information (ngx_http_stub_status_module)
[[inputs.nginx]]
## An array of Nginx stub_status URI to gather stats.
urls = ["http://localhost/server_status"]
```
### Measurements & Fields:
- Measurement
- accepts
- active
- handled
- reading
- requests
- waiting
- writing
### Tags:
- All measurements have the following tags:
- port
- server
### Example Output:
Using this configuration:
```
[[inputs.nginx]]
## An array of Nginx stub_status URI to gather stats.
urls = ["http://localhost/status"]
```
When run with:
```
./telegraf -config telegraf.conf -input-filter nginx -test
```
It produces:
```
* Plugin: nginx, Collection 1
> nginx,port=80,server=localhost accepts=605i,active=2i,handled=605i,reading=0i,requests=12132i,waiting=1i,writing=1i 1456690994701784331

# ntpq Input Plugin
Get standard NTP query metrics, requires ntpq executable.
Below is the documentation of the various headers returned from the NTP query
command when running `ntpq -p`.
- remote – The remote peer or server being synced to. “LOCAL” is this local host
(included in case there are no remote peers or servers available);
- refid – Where or what the remote peer or server is itself synchronised to;
- st (stratum) – The remote peer or server Stratum
- t (type) – Type (u: unicast or manycast client, b: broadcast or multicast client,
l: local reference clock, s: symmetric peer, A: manycast server,
B: broadcast server, M: multicast server, see “Automatic Server Discovery“);
- when – When last polled (seconds ago, “h” hours ago, or “d” days ago);
- poll – Polling frequency: rfc5905 suggests this ranges in NTPv4 from 4 (16s)
to 17 (36h) (log2 seconds), however observation suggests the actual displayed
value is seconds for a much smaller range of 64 (26) to 1024 (210) seconds;
- reach – An 8-bit left-shift shift register value recording polls (bit set =
successful, bit reset = fail) displayed in octal;
- delay – Round trip communication delay to the remote peer or server (milliseconds);
- offset – Mean offset (phase) in the times reported between this local host and
the remote peer or server (RMS, milliseconds);
- jitter – Mean deviation (jitter) in the time reported for that remote peer or
server (RMS of difference of multiple time samples, milliseconds);
### Configuration:
```toml
# Get standard NTP query metrics, requires ntpq executable
[[inputs.ntpq]]
## If false, set the -n ntpq flag. Can reduce metric gather times.
dns_lookup = true
```
### Measurements & Fields:
- ntpq
- delay (float, milliseconds)
- jitter (float, milliseconds)
- offset (float, milliseconds)
- poll (int, seconds)
- reach (int)
- when (int, seconds)
### Tags:
- All measurements have the following tags:
- refid
- remote
- type
- stratum
### Example Output:
```
$ telegraf -config ~/ws/telegraf.conf -input-filter ntpq -test
* Plugin: ntpq, Collection 1
> ntpq,refid=.GPSs.,remote=*time.apple.com,stratum=1,type=u delay=91.797,jitter=3.735,offset=12.841,poll=64i,reach=377i,when=35i 1457960478909556134

# PostgreSQL plugin
This postgresql plugin provides metrics for your postgres database. It has been
designed to parse ithe sql queries in the plugin section of your telegraf.conf.
For now only two queries are specified and it's up to you to add more; some per
query parameters have been added :
* The SQl query itself
* The minimum version supported (here in numeric display visible in pg_settings)
* A boolean to define if the query have to be run against some specific
* variables (defined in the databaes variable of the plugin section)
* The list of the column that have to be defined has tags

```
Please follow the requirements to setup those extensions.
In the database (can be a specific monitoring db)
```
create extension pg_stat_statements;
create extension pg_stat_kcache;
create extension pg_proctab;
```
(assuming that the extension is installed on the OS Layer)
- pg_stat_kcache is available on the postgresql.org yum repo
- pg_proctab is available at : https://github.com/markwkm/pg_proctab

# Prometheus Input Plugin
The prometheus input plugin gathers metrics from any webpage
exposing metrics with Prometheus format
### Configuration:
Example for Kubernetes apiserver
```toml
# Get all metrics from Kube-apiserver
[[inputs.prometheus]]
# An array of urls to scrape metrics from.
urls = ["http://my-kube-apiserver:8080/metrics"]
```
You can use more complex configuration
to filter and some tags
```toml
# Get all metrics from Kube-apiserver
[[inputs.prometheus]]
# An array of urls to scrape metrics from.
urls = ["http://my-kube-apiserver:8080/metrics"]
# Get only metrics with "apiserver_" string is in metric name
namepass = ["apiserver_"]
# Add a metric name prefix
name_prefix = "k8s_"
# Add tags to be able to make beautiful dashboards
[inputs.prometheus.tags]
kubeservice = "kube-apiserver"
```
### Measurements & Fields & Tags:
Measurements and fields could be any thing.
It just depends of what you're quering.
Example:
```
# HELP go_gc_duration_seconds A summary of the GC invocation durations.
# TYPE go_gc_duration_seconds summary
go_gc_duration_seconds{quantile="0"} 0.00010425500000000001
go_gc_duration_seconds{quantile="0.25"} 0.000139108
go_gc_duration_seconds{quantile="0.5"} 0.00015749400000000002
go_gc_duration_seconds{quantile="0.75"} 0.000331463
go_gc_duration_seconds{quantile="1"} 0.000667154
go_gc_duration_seconds_sum 0.0018183950000000002
go_gc_duration_seconds_count 7
# HELP go_goroutines Number of goroutines that currently exist.
# TYPE go_goroutines gauge
go_goroutines 15
```
- go_goroutines,
- gauge (integer, unit)
- go_gc_duration_seconds
- field3 (integer, bytes)
- All measurements have the following tags:
- url=http://my-kube-apiserver:8080/metrics
- go_goroutines has the following tags:
- kubeservice=kube-apiserver
- go_gc_duration_seconds has the following tags:
- kubeservice=kube-apiserver
### Example Output:
Example of output with configuration given above:
```
$ ./telegraf -config telegraf.conf -test
k8s_go_goroutines,kubeservice=kube-apiserver,url=http://my-kube-apiserver:8080/metrics gauge=536 1456857329391929813
