Hi Torkil,
cephadm does regular checks, for example some 'ceph-volume' stuff to
see if all assigned disks have actually been deployed as OSDs and so
on. That's why there are "random" containers created and destroyed. I
don't have a complete list of checks, though. You should be able to
match those timestamps with the /var/log/ceph/cephadm.log, here's an
example from one of my clusters:
# cephadm.log
2024-02-01 00:05:16,491 7f1265f64740 DEBUG

A couple of seconds later it checks "cephadm list-networks" and then
"cephadm ls", and so on. Basically, it's a consistency check.

Zitat von Torkil Svensgaard <torkil@xxxxxxxx>:
So it seems some ceph housekeeping spawn containers without giving
them a name and that causes this in the journal:

We have ceph (currently 18.2.0) log to an rsyslog server with the
following file name format:
template (name="DynaFile" type="string"
string="/tank/syslog/%fromhost-ip%/%hostname%/%programname%.log")
Around May 25th this year something changed so instead of getting
the usual program log names we are also getting a lot of diffent
logs with weird names. Here's an ls excerpt:

Those are container names or something like that? The file content
seems to be assorted bits from the ceph disk tool:

Anyone else had this issue? Suggestions on how to get a real
program name instead?
