lxc-top(1)                                                     lxc-top(1)

NAME         top

       lxc-top - monitor container statistics

SYNOPSIS         top

       lxc-top [--help] [--delay delay] [--sort sortby] [--reverse]

DESCRIPTION         top

       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.

OPTIONS         top

       -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).

EXAMPLE         top

       lxc-top --delay 1 --sort m
              Display containers, updating every second, sorted by memory
              use.

NOTES         top

       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).
