lxc-top — monitor container statistics
Synopsis
lxc-top [--help] [--delay delay] [--sort sortby] [--reverse]
Description
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 terminal. Press 'q' to quit. Press one of the sort key letters to sort by that statistic. Pressing a sort key letter a second time reverses the sort order.
Options
- -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
- lxc-top --delay 1 --sort m
Display containers, updating every second, sorted by memory use.
Notes
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 = numberin your container configuration file, see lxc.conf(5).
