=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, becouse if every guest restart generate new device name, then the graph will be useless
|
||||
( example config : lxc.network.veth.pair = vethsamba )
