Ceph
ZenPacks.zenoss.Ceph
Ceph is a distributed object storage and file system.
This ZenPack monitors the Ceph storage clustering system.
We support two APIs for connecting to Ceph: Calamari and SSH.
Calamari is beneficial when you already have Calamari monitoring setup and don't want to talk directly to your cluster. Calamari caches data and will put less load on your server while maintaining existing security.
The SSH API is appropriate when Calamari monitoring is not desired. This choice is easier to setup if no existing Calamari system exists. For Ceph Octopus and Pacific versions the SSH API make direct contact only to Ceph Admin node (initial monitor node) and pulls data from it. For the older versions the SSH API make direct contact to each host and pulls data from each server and so this API is more direct and reactive. This API choice requires you setup SSH keys or provide SSH password authentication.
