On the Service Discovery page in setup, does it show up under disabled services?

3

No, it doesn’t appear anywhere, even when I disable all the discovery rules.

4

Maybe a hint : Could it be because the mount target “synapse_workplace_data” is in the /var/lib/docker/volumes folder ?

5

OK, I had an answer from the support : volumes mounted in /var/lib/docker/volumes are automatically filtered during inventory. If you want to monitor any volume that you manually mount here, you have to create your custom plugin or MRPE script.

Or change the code inside df.py (which is not such a good idea, because it will be overwritten in the future)
under section: def _filter_df_blocks(…
from if df_block.mountpoint.startswith(“/var/lib/docker/”):
to if df_block.mountpoint.startswith(“/var/lib/docker/”) and not df_block.mountpoint.startswith(“/var/lib/docker/volumes”):

Because even the explicit Mountpoints to never ignore under rule Filesystem discovery are ignored. It would have been nicer if you could have overridden it in the rules section. Or even better, if there was a rule that did this ignoring instead of hard coded in the df.py

Anyway, hope somebody found this useful.

(Hopefully the dev team will swap the codeblocks:
if df_block.mountpoint.startswith(“/var/lib/docker/”)
and
if not _ignore_mountpoint(df_block.mountpoint, never_ignore_mountpoints):
inside df.py that might make it possible to override this behavior the normal rules way.

Thanks. I ended writing my own probe but, yes, I don’t fully understand this behaviour. We should be able to disable this.
