# Gluster Metrics Exporter

## Install

Download the latest release with the command

```
$ curl -fsSL https://github.com/kadalu/gluster-metrics-exporter/releases/latest/download/install.sh | sudo bash -x
```

Test to ensure the version you installed is up-to-date

```
$ gluster-metrics-exporter --version
```

## Usage:

Start the Gluster Metrics exporter service in all the Storage nodes

```
# systemctl enable gluster-metrics-exporter
# systemctl start gluster-metrics-exporter
```

Above command picks up the Gluster hostname by running the `hostname` command. If the local Gluster hostname is different than create a hostname file in `/var/lib/glusterd`.

```
# echo "server1.example.com" > /var/lib/glusterd/hostname
```

To fetch the Prometheus compatible Metrics, call the API from any one Storage node.

```
$ curl http://server1.example.com:9713/metrics
```

To get the same metrics in JSON format

```
$ curl http://server1.example.com:9713/metrics.json
```

## Manually run the exporter (Without systemd)

```
# gluster-metrics-exporter
```
