README

ZFS Prometheus exporter

Exports dataset, pool and disk/vdev statistics in a Prometheus-compatible format. It works (as tested) on Linux and OpenBSD, plus probably others too.

go-libzfs is based around github.com/bicomsystems/go-libzfs with a considerable portion of the libzfs wrapping logic rewritten. Credit goes to that implementation for the framework and pointers on how to reference the largely undocumented (though the source itself was very helpful) libzfs.

Provided is an example Grafana dashboard that looks a little something like this

Usage

The exporter takes very few options. It supports (m)TLS/authentication via exporter-toolkit
