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/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
