We are having issues with some containers and the piggybacked data
Check_MK error :
[piggyback] Successfully processed from source ‘awshost’, Parsing of section docker_container_mem_cgroupv2 failedWARN, execution time 0.5 sec
CheckMK Discovery error :
Services: all up to date, Host labels: all up to date, Parsing of section docker_container_diskstat_cgroupv2 failedWARN, Parsing of section docker_container_mem_cgroupv2 failed
HW/SW Inv error :
Did not update the tree due to at least one errorWARN, Found 45 inventory entries, software changes, hardware changes, Parsing of section docker_container_mem_cgroupv2 failed
To our understanding the data is parsed from the io.stat file in /sys/fs/cgroup/
We think the loop device (7:) reporting is the issue but not sure
root@awshost:/home/admin# cat /sys/fs/cgroup/io.stat

I’ve read an article on an elastic forum where they had somewhat the same issues, so I’m guessing this is a bug …
