Network IO - cgroup - system
What it does
This metric provider reads the total amount of sent and received bytes from the network interface based on the cgroups stats of your system cgroup processes. More information about cgroups can be found in the Linux manual pages.
It can be used for system monitoring and tracking background processes such as the desktop environment. It is also used to calculate GMT’s overhead.
