# Metrics
|
|
|
|
Metrics are emitted via the logs for few couple of reasons:
|
|
|
|
1. Everything supports STDERR.
|
|
2. User can optionally use them, if not, they just end up in the logs.
|
|
3. No particular metrics system required, in other words, all metrics systems can be used via adapters (see below).
|
|
|
|
## Metrics
|
|
|
|
The metrics format follows logfmt format and looks like this:
|
|
|
|
```
|
|
metric=someevent value=1 type=count
|
|
metric=somegauge value=50 type=gauge
|
|
```
|
|
|
|
It's a very simple format that can be easily parsed by any logfmt parser and passed on to another stats service.

## Statsd
|
|
|
|
The [Logspout Statsd Adapter](https://github.com/iron-io/logspout-statsd) adapter can parse the log metrics and forward
|
|
them to any statsd server.
