Not finding mounted cephfs filesystem

I am trying to monitored a few mounted filesystems on a host, one of those is a cephpfs:

10.79.79.11,10.79.79.12,10.79.79.10:/ 99T 81T 19T 82% /mnt/bindmounts/kernel.cephfs

Unfortunately, even if I add an explicit discovery rule, it does not show, checking the raw data, it is also not there.

Can checkmk not monitor mounted network filesystems?

The Checkmk agent uses df with the option -l to monitor only local filesystems.

We developed an agent plugin that specifically adds the info for mounted CephFS filesystems:
