Ceph Exporter GoDoc Build Status

Prometheus exporter that scrapes meta information about a running ceph cluster. All the information gathered from the cluster is done by interacting with the monitors using an appropriate wrapper over rados_mon_command(). Hence, no additional setup is necessary other than having a working ceph cluster.

Dependencies

You should ideally run this exporter from the client that can talk to Ceph. Like any other ceph client it needs the following files to run correctly.

  • ceph.conf containing your ceph configuration.
  • ceph.<user>.keyring in order to authenticate to your cluster.

Ceph exporter will automatically pick those up if they are present in any of the default locations. Otherwise you will need to provide the configuration manually using --ceph.config flag.

We use Ceph's official Golang client to run commands on the cluster.

Flags

Name Description Default
telemetry.addr Host:Port pair to run exporter on *:9190
telemetry.path URL Path for surfacing metrics to prometheus /metrics
ceph.config Path to ceph configuration file ""

Installation

Typical way of installing in Go should work.

go install

A Makefile is provided in case you find a need for it.
