check_lagg_lacp

Project Notes

check_lagg_lacp

Derived from https://github.com/jeanpaulgalea/check_lagg_failover

Nagios plugin for FreeBSD lagg lacp interface.

Alert when a lagg lacp interface has a down or failed slave port.

For more information about lagg interfaces in general;
http://www.freebsd.org/doc/handbook/network-aggregation.html

This check is meant to serve two purposes;

To alert that, for some reason, a child port is not active

This could mean that the nic card is fried, the upstream switch is down, etc.

To give the system administrator as much time as possible in order to bring the master port back online.

This is especially important when the lagg interface is configured with only two ports.

Limitations

This plugin only works when the lagg interface is configured in "LACP Mode". For failover see https://github.com/jeanpaulgalea/check_lagg_failover
Dependencies

nagios-plugins must be installed from the ports tree.
