In regards to troubleshoot a misbehaving systems sar is still the first tool of choice, but it records data only at system level. With cgroup v2 around for several years and in some distros already (or very soon) default, we have a load of system data already collected by the kernel. Thanks to systemd all services and user processes are neatly grouped into a cgroup hierarchy.

Description

The idea is to make Trento checks usable for support cases by using them on supportconfigs and other files usually easy available to Support.
