super. Many thanks again. I will put together these and post my progress. I will do
first the CPU utilization, then go to mem, disk and network io utilizations. I need as well
the get the run-queue length, load average seems very simple. Not sure how hairy things
will get on those parts when I will need per disk or per NIC throughput iops or read KB/sec.
One thing at the time.
Cheers,
