Nagios Plugin for VRF Route Limit Checking (check_vrf_routes)

Description

This is a Nagios plugin to check the route counts on each VRF on your router and validates whether
or not the route count exceeds the mid-water or high-water thresholds.

Examples:

# Route counts in all VRFs below thresholds
./check_vrf_routes.py -H router -C public
OK – All VRFs within thresholds – 3 VRF(s), 6730 total routes | \\\’VRF1\\\’=1625;2400;3000;0;3000 \\\’VRF2\\\’=985;1600;2000;0;2000 \\\’VRF3\\\’=4120;6000;7500;0;7500

# Route counts in one or more VRFs at or above mid-water thresholds
./check_vrf_routes.py -H router -C public
WARNING – 1 VRF(s) exceeded mid threshold – VRF3(4129/3750) | \\\’VRF1\\\’=1626;2400;3000;0;3000 \\\’VRF2\\\’=983;1600;2000;0;2000 \\\’VRF3\\\’=4129;3750;7500;0;7500

# Route counts in one or more VRFs at or above high-water thresholds
./check_vrf_routes.py -H router -C public
CRITICAL – 1 VRF(s) exceeded high threshold – VRF3(7500/7500) | \\\’VRF1\\\’=1626;2400;3000;0;3000 \\\’VRF2\\\’=983;1600;2000;0;2000 \\\’VRF3\\\’=7500;3750;7500;0;7500\\\”
