Hi Ceph User! I had a look at the "official" collectd fork for ceph, which is quite outdated and not compatible with the upstream version. Since this was not an option for us, I've worte a Python Plugin for Collectd, that gets all the precious informations out of the admin sockets "perf dump" command. It runs on our productive cluster right now and I'd like to share it with you: https://github.com/Crapworks/collectd-ceph Any feedback is welcome! Regards, Christian
