I run a rootless podman container on MicroOS. The container is working fine although I get the following warning every 30s when conmon tries to check the memory.events file for the container
conmon 6d47ba2f69f3682e855c <nwarn>: Failed to add inotify watch for /sys/fs/cgroup/user.slice/user-1000.slice/user@1000.service/user.slice/user-libpod_pod_....slice/libpod-....scope/memory.events
The folder exists, but not the memory.events file. I suspect this is because
/sys/fs/cgroup/user.slice/cgroup.subtree_control (and below) only contains pids but not memory like /sys/fs/cgroup/cgroup.subtree_control does.
I don’t think that I do anything special when launching the container, so I’m surprised that I get these warnings. I’ve also tried to disable the memory monitoring by adding the following in my .servicefile but without success:
[Service]
Environment=CONMON_IGNORE_MEMORY_EVENTS=1
Does anyone else see this? Seems like contradictory defaults between conmon and /sys/fs/cgroup/user.slice/cgroup.subtree_control.
