The general idea with mgr plugins (Telegraf, etc) is that because there's only one active mgr daemon, you don't have to worry about duplicate feeds going in. I haven't use the icinga2 check_ceph plugin, but it seems like it's intended to run on any node that has a client keyring, so you wouldn't need to run a mon/mgr locally where you were running the check plugin, just the ceph.conf and keyring file.
