ceph.log file switched to unix timestamp

[Leah]

Hey, after our upgrade to Proxmox 8 with ceph 17.2.7 we observed a strange change in the /var/log/ceph/ceph.log. In this file the format for log timestaps changed to unix time stamps and we have no idea why and couldn't find anything in the ceph docs neither the release notes. All other ceph log files still use the human readable format. Is there an option to change it back to the human readable format?

I can verify this here, but couldn't find the commit yet that introduced that change.

Any news here?

Not much yet, other than that it only seems to be Quincy (Ceph 17) on Bookworm that's affected, while on Bullseye it retains the old format.
There are no source code changes between the Bullseye build and the Bookworm build. It may be a different configuration of something during build, or some external dependency that changes this.
