_ Plugin Downloads: Ībout the Author: Anders is the lead of the Nagios support team. The plugin has been successfully tested on cisco-2811 and beyond.
When it comes to Cisco hardware, it monitors both the modules of the supervisor and the blades (for example, cisco-4500 and cisco-6500).Ĭheck_env_stat.py: This plugin provides temperature logs combined with the SNMP-location (in performance data format),and hence is very useful when it comes to graphing and keeping an eye on the temperature in all the small dusty locations where you might have had to place your network equipment. The functionality has been futher extended by two other plugins Ĭheck_snmp_: This is based on the ‘check_snmp_env’ script with the addition to check Cisco and Extreme hardware blades/modules and all hardware components for Juniper equipment. It has been successfully tested on the most commonly used models, ranging from cisco-1811 to cisco-4503. In the case of Cisco hardware, it monitors fans, power supplies (including RPS-modules) and temperature. The plugin can monitor Cisco, Nokia Ipso, Bluecoat, Ironport and Foundry hardware. Monitoring the hardware of your network equipment doesn’t have to be either expensive or complex, since there are some very useful Nagios plugins out there:Ĭheck_snmp_env has been around for a couple of years now and version 1.2 has proven very useful when monitoring (for example) a mix of Cisco switches. The switches and routers in question are usually quite expensive hardware with well implemented SNMP interfaces, but two things seem to prevent most organisations from adding monitoring of these devices: 1 – They haven’t had any problems with the equipment (yet), and 2 – The software provided by the hardware manufacturer to monitor these devices is too expensive or too complex, when compared to the needs of the organization.
In many organisations the availability of IT-services depend on network eqipment that happens to work well, but isn’t proactively monitored. This month Anders provides insight on monitoring network equipment hardware like switches and routers via SNMP.
