Hi,
Does anyone know why Performance counters return zero value in the code
below when executing under linux mono platform.
(OR)
How to get a process performance counters like CPU,Memory,Thread
count,Handle Count and other resource utilization of a machine,when the
process is running in a remote machine?
The code below works with MS Visual Studio under Windows but simply won't
work with Mono 2.10.5 under linux i.e performance counter values are
zero.why?
/* This uses remoting */
/ * Run this application in the remote machine where the actual
