Problem

How to use the systemd-cgtop command: Show the top control groups of the local Linux control group hierarchy, ordered by their CPU, memory, or disk I/O load. See also: top. More information: <https://www.freedesktop.org/software/systemd/man/latest/systemd-cgtop.html>.

Solution

systemd-cgtop — Show the top control groups of the local Linux control group hierarchy, ordered by their CPU, memory, or disk I/O load. See also: top. More information: <https://www.freedesktop.org/software/systemd/man/latest/systemd-cgtop.html>.

Start an interactive view:

systemd-cgtop

Change the sort order:

systemd-cgtop --order {{cpu|memory|path|tasks|io}}

Show the CPU usage by time instead of percentage:

systemd-cgtop --cpu=percentage

Change the update interval in seconds (or one of these time units: ms, us, min):

systemd-cgtop {{[-d|--delay]}} {{interval}}

Only count userspace processes (without kernel threads):

systemd-cgtop -P
