=head1 INTERPRETATION
|
||||||
|
|
||||||
|
This plugin needs root privilege.
|
||||||
|
|
||||||
|
This plugin has been tested with lxc 3 and
|
||||||
|
lx2 (on Debian buster and Debian jessie,
|
||||||
|
respectively).
|
||||||
|
|
||||||
|
For the network graphs to work, you need
|
||||||
|
to have in every container's config file
|
||||||
|
a line defining the virtual network interface
|
||||||
|
path (else lxc will use a random name at
|
||||||
|
each container's start); see the lxc_netdev()
|
||||||
|
function below.
|
||||||
|
|
||||||
|
If using lxc 2, make sure you do not have cruft
|
||||||
|
in your container config files, you can test
|
||||||
|
it with:
|
||||||
|
lxc-cgroup -o /dev/stdout -l INFO -n 104 cpuacct.usage
|
||||||
|
-- with 104 a valid lxc instance), if you
|
||||||
|
get a warning, fix the config file.
|
||||||
|
|
||||||
|
For the logins graph, the "users" command is required in each
|
||||||
|
container.
|
||||||
|
|
||||||
|
Tested on Debian buster and Debian jessie.

=head1 NAME
|
|
||||||
|
|
||||||
lxc_net - Munin plugin to graph traffic of active LXC containers.
|
|
||||||
|
|
||||||
=head1 APPLICABLE SYSTEMS
|
|
||||||
|
|
||||||
LXC container with "lxc.network.type=veth" and "lxc.network.veth.pair" settings.
|
|
||||||
|
|
||||||
=head1 CONFIGURATION
|
|
||||||
|
|
||||||
env.lxcpath - Set the path where LXC containers are stored, default: /var/lib/lxc
|
|
||||||
env.exclude - Removing containers from graphs, default: empty
|
|
||||||
|
|
||||||
[lxc_net]
|
|
||||||
env.lxcpath /var/lib/lxc
|
|
||||||
env.exclude container1 container2
|
|
||||||
|
|
||||||
=head1 INTERPRETATION
|
|
||||||
|
|
||||||
This plugin reads a "lxc.network.veth.pair" setting from "config" file of each container,
|
|
||||||
because lxc-start command creates a random named veth device without the setting.
|
|
||||||
|
|
||||||
If your xen config (/var/lib/lxc/GUEST_NAME/config does not contain this parameter,
|
|
||||||
then you have to fill it, because if every guest restart generate new device name, then the graph will be useless
|
|
||||||
( example config : lxc.network.veth.pair = vethsamba )

If env.areastack is set to true, all memory usages of containers will be
