I have never heard of that helper, so no, we're not using it - should we?

This "ceph" tool requires installing 90 MB of additional Debian
packages, which I just tried on a test cluster, and "ceph fs top"
fails with "Error initializing cluster client: ObjectNotFound('RADOS
object not found (error calling conf_read_file)')". Okay, so I have to
configure something.... but .... I don't get why I would want to do
that, when I can get the same information from the kernel without
installing or configuring anything. This sounds like overcomplexifying
the thing for no reason.
