ceph dashboards using grafana and prometheus

cephmetrics

Cephmetrics is a tool that allows a user to visually monitor various metrics in a running Ceph cluster.

This fork is a really stripped down version of cephmetrics more suitable for deployment on non-Redhat installations. The required infrastructure (Prometheus, Grafana) is also deployed via docker-compose.

We assume that the deployment of node_exporter on all hosts and enabling the ceph-mgr prometheus plugin are taken care of by the user.

Mostly we just keep the excellent dashboards :)

Currently we've only tested this version against a Luminous Ceph mgr prometheus end point.

Configuration

To get going you only really need to modify prometheus/prometheus.yml to configure the Ceph manager to scrape and the node exporter addresses for each physical host in your Ceph cluster.

The example config file just uses localhost in the various targets sections.

To use email based alerting you can also put sensible values into grafana/config.monitoring for the SMTP_HOST and the SMTP_FROM_ADDRESS.

cephmetrics's Issues

prometheus health check

In the docker compose file, prometheus has a health check:

    healthcheck:
        test: ["CMD", "curl", "-f", "http://localhost:9090"]
        interval: 30s
        timeout: 10s
        retries: 5

Seems that this is run inside the docker contain, so prom/prometheus:v2.1.0 needs to have curl installed.
