Nagios plugin to monitor Cisco IronPort Email Security Appliances via SNMP
License: MIT License
NAME check_ironport_snmp - Nagios plugin to monitor Cisco IronPort Email Security Appliances via SNMP REQUIREMENTS * You will need a recent version of Net-SNMP <http://www.net-snmp.org/> * You will have to load the MIBs ASYNCOS-MAIL-MIB.txt and IRONPORT-SMI.txt which you can download from IronPort's support page <http://www.cisco.com/web/ironport/> * You will need to activate SNMP on your IronPort Email Security Appliance(s) DESCRIPTION This script acts as a plugin module for the Nagios IT infrastructure monitoring system. It polls an IronPort Email Security Appliance for status information through SNMP, parses for the requested value, compares that value against warning and critical levels, and responds with a status string and appropriate exit status. This script handles authentication (only when using SNMPv3) and the following checks: * cpu (CPU utilization, measured in percent) * mem (Memory utilization, measured in percent) * memoryavail (Memory availability status, does not require thresholds) * diskio (Disk I/O utilization, measured in percent) * queue (Queue utilization, measured in percent) * queueavail (Queue availability status, does not require thresholds) * resourceconservation -> Resource Conservation Reason, does not require thresholds) * temperature (Device temperature, measured in °C) * raid (RAID status, does not require thresholds) * fan (Fans status, does not require thresholds) * psstatus (Power supply status, does not require thresholds) * psredundancy (Power supply redundancy, does not require thresholds) * openfiles (Open files or sockets) * mailtransferthreads (running mail transfer threads) * dns (Pending and outstanding DNS requests) This has been tested with two Cisco IronPort C160 appliances and a Nagios 3.2 installation under Ubuntu Linux 10.04. You will ideally want to use a secured connection over SNMPv3 using a passphrase provided with the parameter -P. The user name defaults to 'v3get' in this case. At very minimum, it would be good practice to whitelist any IPs which will need access to status information on the IronPort Appliance. SYNOPSIS Command Line Interface Poll CPU utilization with SNMPv2c without encryption or authentication: check_ironport_snmp -H example.com -C public -t cpu -w 90 -c 98 Poll RAID status with SNMPv3: check_ironport_snmp -H example.com -v 3 -C my_community -P secret \ -t raid Running within Nagios In your command definitions (e.g. objects/commands.cfg): define command{ command_name check_ironport command_line $USER1$/check_ironport_snmp -H $HOSTNAME$ \ -C $ARG1$ -t $ARG2$ -c $ARG3$ -w $ARG4$ } define command{ command_name check_ironport_auth command_line $USER1$/check_ironport_snmp -H $HOSTNAME$ -v 3 \ -C $ARG1$ -P $ARG2$ -t $ARG3$ -c $ARG4$ -w $ARG5$ } In the configuration file for your IronPort Email Security Appliance: define service{ use my-service-template host_name example.com service_description CPU Utilization check_command check_ironport!public!cpu!90!95 } define service{ use my-service-template host_name example.com service_description Open Files or Sockets check_command check_ironport!public!openfiles!200!300 } define service{ use my-service-template host_name example.com service_description Queue Utilization check_command check_ironport_auth!public!secret!queue!80!90 } define service{ use my-service-template host_name example.com service_description Memory Utilization check_command check_ironport_auth!public!secret!mem!90!95 } AUTHOR This script is written and maintained by Jochen Schalanda <[email protected]> and is available on GitHub, at <https://github.com/joschi/check_ironport_snmp>.
