nagios-plugins

Nagios plugins written in python that check services on network devices over snmp. Each plugin returns an int according to nagios specifications ( 0 - ok, 1 - warning, 2 - critical, 3 - unknown ).

Scripts that check the CMTS will also output additional information to stdout that the notify script will parse and use to create better notifications types.

nagios-plugins.js is a javascript file that contains sample code for generating nagios settings that the plugins use

check_type config option, available only for server
  lt - current value on the device has to be lower than warning/critical
  gt - current value on the device has to be higher than warning/critical

Examples of plugin input data below.
