Linux Check PPS, BPS, or Current Line Rate % of NIC

Project Notes

Nagios plug-in that calculates receiving PPS, BPS, and percentage of line-rate (LR) from Linux kernel statistics by reading from procfs and reports if above a given threshold.

Options:

-i Network interface
-p Use PPS as criteria
-b Use BPS as criteria
-r Use percentage of line-rate as criteria
-t <int> Time interval in seconds (def: 1)
-w <int> Warning threshold
-c <int> Critical threshold

# Examples: #
###########

# 1.) Return critical if there's more than 10k PPS
# $ ./check_pps.sh -i eth0 -w 8000 -c 10000 -p
#
# 2.) Return critical if there's more than 1m BPS
# $ ./check_pps.sh -i eth0 -w 500000 -c 1000000 -b
#
# 2.) Return critical if we've reach 70% of the NIC's line-rate capacity
# $ ./check_pps.sh -i eth0 -w 50 -c 70 -r
