I recommend to NOT set the identifier to 'VM-2'.
I wrote the Zabbix module and a bit of background.
If you don't set the identifier the fsid (uuid) of the cluster will be used.
You now used 'VM-2', but it's not guaranteed that the ceph-mgr will run
on that host. If the Mgr fails over to a different host it will not be
'vm-2' sending the data.
Usually I just leave identifier empty and just use the fsid of the
cluster as hostname in Zabbix.
