I utilize a combination of Cacti for performance monitoring and Argus (http://argus.tcp4me.com/) for fault monitoring. In addition to those two, I have Smokeping (http://oss.oetiker.ch/smokeping/) monitoring the connection latency of specific remote servers. Those three are light-weight enough from my network, but Zenoss (http://www.zenoss.com/), OpenNMS (http://www.opennms.org/index.php/Main_Page), and JFFNMS (http://www.jffnms.org/) are bigger systems that are worth a look. -- =W On Sat, Mar 8, 2008 at 3:57 AM, Neil A.
