SNMP + rrdtool should give you everything you need. MRTG can do the graphing for you. I've used http://www.steveshipway.org/software/index2.html, and it offers 95th percentile reports, and has configurable 'work hours', that you can use monitor specific portions of the day. -- Matthew Walker Kydance Hosting & Consulting, Inc. - http://www.kydance.net/ PHP, Perl, and Web Development - Linux Server Administration /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
