lxc-monitor — monitor the container state


lxc-monitor [-n name] [-Q name]


lxc-monitor monitors the state of containers. The name 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, name will default to '.*' which will monitor all containers in lxcpath.

The -P, --lxcpath=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.


-Q, --quit

Ask the lxc-monitord daemon on each given lxcpath 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 lxcpath is on.

Common Options

These options are common to most of lxc commands.

-?, -h, --help

Print a longer usage message than normal.


Give the usage message

-q, --quiet

mute on

-P, --lxcpath=PATH

Use an alternate container path. The default is /var/lib/lxc.

-o, --logfile=FILE

Output to an alternate log FILE. The default is no log.

-l, --logpriority=LEVEL

Set log priority to LEVEL. The default log priority is ERROR. Possible values are : FATAL, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG.

Note that this option is setting the priority of the events log in the alternate log file. It do not have effect on the ERROR events log on stderr.

-n, --name=NAME

Use container identifier NAME. The container identifier format is an alphanumeric string.


Specify the configuration file to configure the virtualization and isolation functionalities for the container.

This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create).


Show the version number.


lxc-monitor -n foo

will monitor the different states for container foo.

lxc-monitor -n 'foo|bar'

will monitor the different states for container foo and bar.

lxc-monitor -n '[fb].*'

will monitor the different states for container with the name beginning with letter 'f' or 'b'.

lxc-monitor -n '.*'

will monitor the different states for all containers.


The container was not found

The specified container was not created before with the lxc-create command.
