> 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`.

- Start an interactive view:

`systemd-cgtop`

- Change the sort order:

`systemd-cgtop {{[-i|--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`
