Re: [perfmon2] Counters' value perthread/systemwide

[Tanima D. <dey...@ya...>]

Hi,
I am sorry I missed it. 
I actually wanted to know the approximate difference between the summation of per-thread counters' values and the system-wide value. Are there any other ways to know it?
Thanks
Tanima.

No it's not. But you did not tell why you think that's needed for what you want
