check_snmp_proc.sh

This is small Nagios plugin for checking status of processes (or quantity of them) via SNMP

This plugin uses the utils.sh from monitoring-plugins.org to be able to use ranges for warning and critical thresholds.

Usage:

./check_snmp_proc -H 127.0.0.1 -C public -N ssh -w 3 -c 0

Where:
  -H hostname /string/
     Name or IP address of host (default 127.0.0.1)
  -C OID /string/
     Community name for the host SNMP agent (default public)
  -N Process name /string/
     Exact process name (default snmpd)
  -w warning level /integer/
     Warning level of running processes (default: 0)
  -c critical level /integer/
     Critical level of running processes (default: 0)
  -m minimum level /integer/
     Minimum level for performance data (default: 0)
  -M maximum level /integer/
     Maximum level for performance data (default: 100)
  -h help
     Print this help screen
  -V version number
     Print version and license information </dd>

  This plugin uses the 'snmpwalk' command included with the NET-SNMP package.
