Using net-snmp to gather SNMP-Data using active checks (win32)

By using active checks, you can easily log SNMP-data without having to open up port 161 on your monitored hosts. You can also use this method with active checks to log SNMP-Data from hosts behind NAT-translating firewalls that you would not be able to monitor using regular SNMP-checks.

The installation is extremely easy:

1. Download the latest win32-build of net-snmp (http://net-snmp.sourceforge.net/)
2. Install somewhere. For the sake of this howto, we assume the installation path is c:\zabbix\net-snmp
3. Add the following line to zabbix_agentd.conf: UserParameter=snmpget[*],c:\zabbix\net-snmp\bin\snmpget.exe -OaeQtUv0 -c public -v 1 localhost $1
4. Done!

You can now use snmpget[<OID>] to monitor your hosts without requiring your zabbix server to be able to connect to the snmp-service on your monitored host.
