Adds Ceph service detection plugin
Adds a Ceph detection plugin to include individual ceph-daemon entries to process.yml. The plugin is similar to a OpenStack service plugin but there are differences in the way we monitor individual instances of each service daemon.
The Ceph services comprise of three main daemons:
- Object Storage Daemon (OSD)
There is a OSD service process per disk added in the cluster and has a corresponding daemon identifier at /var/lib/ceph/osd/
- Monitor Servers (MON)
There is a Monitor service process per monitoring host in the cluster and has a corresponding daemon identifier at /var/lib/ceph/mon/
- Metadata Servers (MDS)
There is a MDS service process per monitoring host in the cluster and has a corresponding daemon identifier at /var/lib/ceph/mds/
Unlike OpenStack services monitoring a single instance of a service will be of no use for Ceph. Every daemon needs to be monitored. This can be achieved by scanning through the daemon identifiers.
