Maybe it's just me, but I'd go with ganglia before nagios if you wanted to monitor network usage. We're using both ganglia and nagios here, and they serve fundamentally different needs, really. Nagios is there to periodically ask "Is (stuff) within (acceptable parameters)? If not, mail people at (contact group) and take (other appropriate action)." Ganglia is there to poll nodes periodically, collect data, display that data in a pretty web frontend, and retain that data for a year in RRD files. However, if you want per-machine bandwidth stats, you WILL have to install a monitoring service like Ganglia's gmond on each machine. Unless you have all the machines plugged into a smart switch, or the gateway is a smart box. If either of those conditions hold true, you can write something or use existing utilities on that switch/box to get some stats. Ganglia would probably be easier/more flexible. Are there any 'Doze boxes in this network? There's probably some sort of gmond workalike for 'Doze now, but I've only ever used it on Unix-like OSes. -- Matt G / Dances With Crows The Crow202 Blog: http://crow202.org/wordpress/ There is no Darkness in Eternity/But only Light too dim for us to see --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
