Relevant telegraf.conf:

[[inputs.ceph]]
ceph_binary = "/usr/bin/ceph"
socket_dir = "/var/run/ceph"
mon_prefix = "ceph-mon"
osd_prefix = "ceph-osd"
socket_suffix = "asok"

I also have just experienced this permissions issue. In my case adding the user telegraf to the ceph group didn’t help as only the ceph user has permission to access the sockets. As a workaround I’ve started running Telegraf as user ceph (!), but with this the Ceph input plugin works successfully and we can at least see if all the metrics we require are available.
