Snmp env check
Script : check_snmp_env.pl Last update : April 19 2007
Description : Checks by snmp v1, v2c or v3 environemental parameters such as fan, power supply, temperature SNMP Login See snmp info page Requirements : - Perl in /usr/bin/perl - or just run 'perl script' - Net::SNMP - file 'utils.pm' in plugin diretory (/usr/local/icinga/libexec) Checks The script will make the following checks depending on host type. Either the threshold is directly set by the hardware manufacturer, or you must set them with an option. This table shows what the script CAN check, depending on hardware version the sensors might not be there. The script will return "UNKNOWN" if no sensors can be found. If no option is specified in this table, it means the script uses the threshold of the snmp table.
Host type | Option | Power supply | Fan | Voltage | Temperature | Disks
Cisco | cisco | Yes | Yes | No (working on it) | No (working on it) | No
Nokia Ipso | nokia | Yes | Yes | No. | Yes | No
Bluecoat | bc | Yes | Yes | Yes | Yes | Yes
IronPort | iron | Yes | Yes, option '-F' in RPM | No | Yes, option '-c' in Celcius | No
Foundry | Foundry | Yes | No (bug in snmp agent) | No | Yes | No
Note : Bluecoat provides an "other" sensor which is tested also. But I never saw a Bluecoat reporting it. Dowload lastest version : 1.2 Configurations examples Changelog : On CVS repository on sourceforge : http://nagios-snmp.cvs.sourceforge.net/nagios-snmp/plugins/. Examples : All examples below are considering the script is local directory. Host to be checked is 127.0.0.1 with snmp community "public".
