# fastd-exporter
We are building a prometheus exporter for the [fastd](https://projects.universe-factory.net/projects/fastd/wiki) vpn daemon.
We are building a prometheus exporter for the [fastd](https://projects.universe-factory.net/projects/fastd/wiki) vpn daemon.
We have a working version, but the metrics, and by extension their labels, are not stable yet.
When they are we will very likely be tagging our first release.

and
```
$ ./fastd-exporter --instance ffda
$ ./fastd-exporter --instance ffda --metrics.perpeer
```
The exporter will need read access to both the instances `fastd.conf` and `status socket`, keep that in mind.
