<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.
