This nagios/icinga plugin simply connects to a ceph-dash instance, gathers the information about the overall cluster health and outputs a nagios compatible message including several perfdata metrics.

Just plain python. Uses urllib2 to gather data from the ceph-dash instance.
./check-ceph-dash.py --url 'http://url.to.ceph.dash/'

By using the generated performance data and sending them to a graphite backend, you can create quite fancy metric dashboards. See the following screenshot for an example (the frontend is Graphana). I have included the configuration file in the contrib folder. You just have to edit the field with <YOUR_GRAPHITE_PREFIX> to your graphite data sources.
