NAME

if_ - Wildcard-plugin to monitor traffic and errors on network interfaces.

CONFIGURATION

This plugin does not normally require configuration.

The plugin may need to run as root to determine the maximum speed of the network interface. This is configured like this:

  [if_*]
      user root

If the interface speed cannot be determined automatically by this plugin, you may manually configure the speed using the "speed" environment variable, in megabits per second, like this:

  [if_*]
      env.speed 1000

To set warning and critical levels do like this:

  [if_*]
      env.warning 10000000

or

  [if_*]
      env.if_0_warning 10000000

This is a wildcard plugin. To monitor an interface, link if_<interface> to this file. For example,

  ln -s /usr/share/munin/plugins/if_ \
        /etc/munin/plugins/if_eth0

will monitor eth0.

Most devices found in /proc/net/dev can be monitored. Examples include ipsec*, eth*, irda*, and lo. Please note that aliases cannot be monitored with this plugin.
