# cgroup Prometheus exporter
The `cgroup_exporter` produces metrics from cgroups.
This exporter by default listens on port `9306` and all metrics are exposed via the `/metrics` endpoint.
# Usage
The `--config.paths` flag is required and must point to paths of cgroups to monitor. If there is `/sys/fs/cgroup/cpuacct/user.slice` then the value for `--config.paths` would be `/user.slice`.
## Docker
Example of running the Docker container
```
docker run -d -p 9306:9306 -v "/:/host:ro,rslave" treydock/cgroup_exporter --path.cgroup.root=/host/sys/fs/cgroup
```
## Install
Download the [latest release](https://github.com/treydock/cgroup_exporter/releases)
## Build from source
To produce the `cgroup_exporter` binaries:
```
make build
```
Or
```
go get github.com/treydock/cgroup_exporter
```
## Process metrics
If you wish to collect process information for a cgroup pass the `--collect.proc` flag. If this exporter is not running as root then it's required to set capabilities to ensure the user running this exporter can read everything under procfs:
```
setcap cap_sys_ptrace=eip /usr/bin/cgroup_exporter
```
## Metrics
Example of metrics exposed by this exporter when looking at `/user.slice` paths:
