Monitoring the Common Address Redundancy Protocol (CARP) on FreeBSD systems.

There are custom low-level discovery rules for detecting all the configured Virtual Host IDs (VHID) and virtual IP addresses as well as user parameters for monitoring the current status of VHIDs and VIPs. Refer to the CARP(4) man page for more information regarding CARP.

The discovery rules and user parameters were tested on pfSense based systems but should work on all FreeBSD 10 and later systems.

Refer to the README for a list of features, supported items, triggers, graphs, macros and installation instructions.
