I'll add a plug for XYMON: http://sourceforge.net/projects/xymon/ Grew out of Big Brother, and the developer is still making improvements. Much simpler than some of the packages mentioned above, and I find it very simple to extend its functionality as well. SNMP monitoring is a bit weak, but doable. Linux monitoring is very strong, with a small agent that runs on each system (non-privileged user). Very customizable alerts, configured on the central server. -- Jon Dustin - Network Specialist University of Southern Maine Portland, ME 207-780-4152 _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
