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 Time interval in seconds (def: 1) -w Warning threshold -c 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
