lxc-top(1) lxc-top(1)
lxc-top - monitor container statistics
lxc-top [--help] [--delay delay] [--sort sortby] [--reverse]
lxc-top displays container statistics. The output is updated every
delay seconds, and is ordered according to the sortby value given.
lxc-top will display as many containers as can fit in your termi‐
nal. Press 'q' to quit. Press one of the sort key letters to sort
by that statistic. Pressing a sort key letter a second time re‐
verses the sort order.
-d, --delay delay
Amount of time in seconds to delay between screen updates.
The default is 3 seconds.
-s, --sort sortby
Sort the containers by name, cpu use, or memory use. The
sortby argument should be one of the letters n,c,b,m,k to
sort by name, cpu use, block I/O, memory, or kernel memory
use respectively. The default is 'n'.
-r, --reverse
Reverse the default sort order. By default, names sort in
ascending alphabetical order and values sort in descending
amounts (ie. largest value first).
lxc-top --delay 1 --sort m
Display containers, updating every second, sorted by memory
use.
For performance reasons the kernel does not account kernel memory
use unless a kernel memory limit is set. If a limit is not set,
lxc-top will display kernel memory use as 0. If no containers are
being accounted, the KMem column will not be displayed. A limit
can be set by specifying
lxc.cgroup.memory.kmem.limit_in_bytes = number
in your container configuration file, see lxc.conf(5).
