<title>Description</title>
<para>
<command>lxc-monitor</command> monitors the state of containers. The
<replaceable>name</replaceable> argument may be used to specify
which containers to monitor. It is a regular expression, conforming
with posix2, so it is possible to monitor all the containers,
several of them or just one. If not specified,
<replaceable>name</replaceable> will default to '.*' which will
monitor all containers in <command>lxcpath</command>.
</para>
<para>
The <option>-P, --lxcpath</option>=PATH option may be specified multiple
times to monitor more than one container path. Note however that
containers with the same name in multiple paths will be
indistinguishable in the output.

<para>
Ask the lxc-monitord daemon on each given <command>lxcpath</command>
to quit. After receiving this command, lxc-monitord will exit
immediately as soon as it has no clients instead of waiting the
normal 30 seconds for new clients. This is useful if you need to
unmount the filesystem <command>lxcpath</command> is on.
