SNMP Community Patches – Nagios 2.x

Project Notes

To use this patch, add to your hosts definitions the variable community with the SNMP community of the host:

define host{

use Template
host_name XXXX
alias XXXX
address XXXX
hostgroups XXXX
community public
}

The community is read by nagios on startup and is copied into the env variable SNMPCOMMUNITY to be used into the checks definition.

So the check definition can be:

$USER1$/check-mysnmp -C $SNMPCOMMUNITY$ -H $HOSTADDRESS$

and on each call of the plugin the right snmp community is used for the check execution.

A warning is generated on the nagios execution if the community is not set for a particular host.

The patch has been tested on nagios 2.0b4 and has to been applied to the nagios sources with patch -p0
