Help

Netdata isn’t showing up systemd (cgroups.plugin) memory related charts. Why could this happen?

Only cpu and pids,

My netdata config is the default. My machine version is,

pi@raspberrypi:/opt/netdata/etc/netdata $ uname -a
Linux raspberrypi 5.15.84-v7+ #1613 SMP Thu Jan 5 11:59:48 GMT 2023 armv7l GNU/Linux
pi@raspberrypi:/opt/netdata/etc/netdata $ lsb_release -a

PD: is it possible to show container friendly names instead of container ids?

Hi.

This happens because this data is not available. Memory is /sys/fs/cgroup/memory/ for group v1 and {CgroupDir}/memory.* files for group v2.

is it possible to show container friendly names instead of container ids?

You need to add netdata user to the docker group. It will allow Netdata to query Docker Engine to resolve container names.
