Hi,

I want to find out the way to finding to know which processor is blocking another from the profiler trace.

Actually we took profiler trace. We observed one process is taking long time but there is no cpu time. We suspect of blocking. How to identify from that trace which process is blocking that? Are really blocking occurred or not?

In the profiler trace, if we find less cpu and high reads. Is that means something is blocking? Please let me know

Thanks,
Ramana

Query performance measures alone won't show you what is blocking or being blocked. Since you're on 2012 you can use the blocked_process_report extended event. That will tell you what is blocked and blocking. You can read more about it here.

You can't find it that way. Either you need to use Blocked Process report in profiler or use extended events as Grant mentioned.
