Is func really the right tool for this job? net-snmp reports this kind of information, is almost certainly installed (or easy installable) on every unix host you have, if relatively easily configured to give you basic information on the host, and can be extended to report anything about the host. Additionally a ton of tools exists for polling/capturing/graphing the data you can get from snmp: http://www.cacti.net (because we use it) http://en.wikipedia.org/wiki/Comparison_of_network_monitoring_systems If you're worried about network capacity, you can use snmp traps to only log when certain events occur and so cut down on polling. > Bye > Marco > > -- > Dott.
