Cgroup-level and system-wide metrics are reported now

Official CH changelog text
Cgroup-level and system-wide metrics are reported now altogether. Cgroup-level metrics have names CGroup<Metric> and OS-level metrics (collected from procfs) have names OS<Metric>. #84317 (Nikita Taranov).
Reporting of cgroup-level and system-wide metrics together has been introduced. Metrics from cgroups are prefixed with CGroup<Metric>, while OS-level metrics collected from procfs use the prefix OS<Metric>.

Why it matters

This feature addresses the need to monitor both container (cgroup) specific resource usage alongside overall system resource metrics in a unified way. It provides more comprehensive insights into resource consumption, enabling better performance analysis and troubleshooting.

How to use it

No special configuration is required to enable this feature. Users will receive both cgroup-level and OS-level metrics automatically, distinguishable by their CGroup and OS prefixes in metric names.
