Zenoss is a web-based SNMP management/monitoring tool that you can use to track the health of your servers and networking infrastructure. Zenoss comes in two editions, Core and Enterprise. This will be a short how-to on setting up Zenoss Core to monitor your home/lab network with SNMP. I won't go over setting up the various options of Zenoss, I'll let you read about that on their docs.

Start by downloading and installing the appropriate version of Zenoss for your distribution, or a VMware image if you want to go that route. I installed the Zenoss stack on an Ubuntu 10.04 virtual machine.

sudo dpkg -i zenoss-stack_3.1.0_i386.deb

The next thing to do is configure SNMP on all the machines you want to monitor.
