OpenNMS focuses on three main areas: 
	Service Polling - determining service availability and reporting on same. 
	Data Collection - collecting, storing and reporting on network information as well as generating thresholds. 
	Event and Notification Management - receiving events, both internal and external, and using those events to feed a robust notification system, including escalation 
 <UL>
	<LI>SNMP, HTTP, JMX Data collection</LI>
	<LI>Graphical Reports</LI>
	<LI>Polling / Monitoring </LI>
	<LI>Auto discovery</LI>

Munin is a networked resource monitoring tool that can help analyze and monitor the performance of your computers, networks, SANs and applications. It is capable to identify "what's different today" and when the performance problem crops up? Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for data. It then stores the data in RRD files, and (if needed) updates the graphs. Munin emphasis on Plug and Play. Check out its <A HREF="http://exchange.munin-monitoring.org/" target="_blank">plugin repository</A>. Demo: <A HREF="http://munin.ping.uio.no/" target="_blank">http://munin.ping.uio.no/</A>
