Check if Icinga2 perfdata are garbage collected

https://icingaweb2.tails.boum.org/monitoring/service/show?host=ecours.tails.boum.org&service=system_disks shows that 80% of inodes are used on ecours’ system partition. That’s because of /var/spool/icinga2/perfdata, that uses no less than 174K inodes today. Are those very many files cleaned up at some point?
