I'd use SNMP. I graph the basic stuff you're looking for with RRDtool: <URL:http://www.campin.net/perl/RRDsnmp.cgi?host=vpn-pat> I don't do any I/O stuff, but you could look for it in the MIB2 host MIB or UCD enterprise MIBs - I'm sure there's something. If there isn't, do what I do for DNS stat graphing and fire off a shell script to extend it: <URL:http://www.campin.net/DNS/graph.html> A major benefit to using SNMP is that many other network monitoring and management systems utilize it, so if you deploy one it'll be able to work with your existing infrastructure. -- Nate Campi http://www.campin.net I have a spelling checker It came with my PC; It plainly marks four my revue Mistakes I cannot sea.
