SNMP is not as difficult as it may seem. It can be your best friend and open a lot of doors. Once you learn to write SNMP commands you will see it is no different than learning Linux commands. Maybe try writing a bash or pearl script with some basic SNMP commands to help your issue? tcpdump is another cool tool to use to verify your SNMP data is arriving and behaving properly.
