check_extreme_fans.pl

This script monitors the fan status of an Extreme Networks device via SNMP.

It accepts the following arguments:

• -s <SWITCH> the switch’s hostname or ip address
• -C <COMMUNITY-STRING> the community string as configured on the switch
• -T <TIMEOUT> optionally provide a timeout in seconds. This timeout defaults to the value configured in /usr/lib/nagios/plugins/utils.pm (usually something around 15 seconds).
• -h show the help.

Tested with different XOS versions and SNMP protocol version 2c. If you want to use a different SNMP protocol version, just modify the Net::SNMP->session(...) call.

Here is the code.

Dependencies

• Net::SNMP
• Getopt::Long

Please consider to take a look at my general setup notes.
