Prometheus Exporter for Heketi Controlled Gluster Gluster

heketi_exporter

Heketi exporter for Prometheus. Currently only authenticated Heketi servers are supported.

The purpose of this exporter was to get the metrics of a Heketi Controlled Gluster Cluster for Openshift Container Native Storage.

A very simple Openshift Template is included to deploy this exporter into a project. This exporter should be deployed into the same project as Prometheus.

Installation

go get github.com/ttindell2/heketi_exporter
./heketi_exporter
