check_linux_nic_buffer


Nagios and Icinga2 plugin to check the pkts_rx_OOB and ring_full counter of Linux interfaces.


Dependencies


This plugin requires:


    

  • Python3
    • 



How it works


The plugin executes ethtool -S to get the device statistics.


Performance data


This plugin provides the following metrics:


    

  • pkts_rx_OOB
    • 

  • ring_full
    • 



Only the metric specified by -m|--metric will be reported. Thresholds are optional and will be appended.


Usage


See the examples below or execute the plugin with -h/--help.


Examples


Check the ring_full counter for eth0 with a warning threshold of 300 and a critical threshold of 1000:


./check_linux_nic_buffer -i eth0 -m ring_full -w 300 -c 1000


Check the pkts_rx_OOB counter for eth0 with a critical threshold of 500:


./check_linux_nic_buffer -i eth0 -m pkts_rx_OOB
