I wrote a small script to collect the snmp data from the Brocade fibre switches and put the data into Servergraph. Next I created a report to graph the data and in that way we could see historical data throughput and identified more than once a faulty tape drive! You definitely want to monitor your

Instead of selecting 'a' on nmon try '^' instead. This will give you the FC adapter stats from fcstat. At least it does on version 12e of nmon. Rick Saylor Austin Community College At 04:59 AM 2/27/2009, you wrote: Stef Coene wrote: > > On Friday 27 February 2009, David Bronder wrote: > > > > U
