Hello Pedro, or anyone else affected,

Accepted ceilometer into victoria-proposed. The package will build now

the -proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:victoria-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,

does not fix the bug for you, please add a comment stating that, and
change the tag to verification-victoria-failed. In either case, details

Bug description:
  Bionic/Stein - stable 20.05 charms
  Juju 2.7.6

  I am aware of: https://bugs.launchpad.net/charm-ceilometer-agent/+bug/1850846
  Decided to open a new bug since there was no activity on the previous one and it expired.

  After rebooting my cloud (rack-by-rack), I got into a situation where
  I could not collect memory.usage from VMs anymore.

  Looking into: openstack metric resource --type instance <ID>
  I could not see memory.usage there.

  Access to ceilometer-agent and I could see the services were on active/running status, but following log was present:
  Jun 27 22:34:09 sgdemr0114bp033 ceilometer-agent-compute[2244]: Deprecated: Option "logdir" from group "DEFAULT" is deprecated. Use option "log-dir" from group "DEFAULT".                                       
  Jun 27 22:34:09 sgdemr0114bp033 ceilometer-agent-compute[2244]: libvirt: XML-RPC error : Failed to connect socket to '/var/run/libvirt/libvirt-sock-ro': No such file or directory                               
  Jun 27 22:34:09 sgdemr0114bp033 ceilometer-agent-compute[2244]: message repeated 33 times: [ libvirt: XML-RPC error : Failed to connect socket to '/var/run/libvirt/libvirt-sock-ro': No such file or directory] 

  
  stat on that /var/run file shows me:
  stat /var/run/libvirt/libvirt-sock-ro
    File: /var/run/libvirt/libvirt-sock-ro
    Size: 0               Blocks: 0          IO Block: 4096   socket

  Change: 2020-06-27 22:34:11.010520529 +0000
   Birth: -

  
  So, I guess there is a race-condition here, where libvirt is opening the socket after ceilometer-agent-compute tried to reach out for it; which gives up and stop working.

  Restarting it restores memory.usage back to normal.

  However, I still cannot see all the metrics as shown in:
