Kings of Open Source Monitoring

"Network monitoring is a fact of life for IT departments. Monitoring software ranges from simple ICMP-based scripts for up/down monitoring to midrange products like SolarWinds to high-end offerings such as HP's OpenView and IBM's Tivoli -- all of which have their drawbacks. Simpler monitoring systems don't provide enough information about your network, while the feature-laden high-end systems can be prohibitively expensive. At the same time, midrange systems might not scale well for monitoring large networks.

"Two network monitoring systems with open source roots, OpenNMS and Zenoss, provide a bevy of features at a lower (or no) cost than their high-end competitors, and can scale to monitor large numbers of network nodes. Both solutions compete with large commercial systems such as OpenView and Tivoli. They are advanced systems capable of monitoring a wide variety of network devices. OpenNMS is completely open source, while Zenoss offers Core, a free open source edition that can be extended with free Zenoss- and community-built add-ons."
