Hi,
I am trying to analyze performance for a variety of parallel applications
using perfmon2; however, i haven't had any success yet.
For example, to collect the number of offcore requests, I used the following
command (see below). But the printed message seems to suggest the reported
count is a bogus value.
Can anyone help with this?
Thanks very much in advance,
Carole

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
