[Check_mk (english)] cmk plugin for ceph mimic broken

Archive checkmk-en

Hi all,

unfortunately I boasted CMK to be able to handle ceph natively with 1.5 while talking to one of our storage guys.
Now, we are using Mimic (version 13.X) of ceph and they changed the output of "ceph df" in Mimic...:frowning:
Now, (at least) the df check is broken. Has anyone already fixed that (before I start patching the code)?
Officially I suggest using the json-option of ceph df like mentioned here:

But this means patching the agent AND the check code.

Any thoughts?

Best regards
Maik

Hi all,

I felt like fixing the issue myself. If you are in need of tests working with Mimic, (ab)use the files linked here:
https://hessenbox.uni-kassel.de/dl/fiRoyzHX3vriWmEWzCmask4G/ceph_new.zip

They should work with older versions of ceph, too, but I wasn't able to test it.

Best regards
Maik

output of 'ceph df' seems to be changed in mimic-Release · Issue #42 · ceph/ceph-nagios-plugins · GitHub

Our extension for monitoring Ceph uses the JSON output of the ceph
commands and works with Mimic:

I do not know why the Check_MK team started to develop their own Ceph
checks…

That fixes ceph_df with Check_MK 1.5.0p11 Raw for me.

Thank you.
