Re: [Gems-users] Understanding ruby stats

["Lei Yang" <lya755@xxxxxxxxxxxxxxxxxxxx>]

I think I understand the stats now. >From left to right: L1 state, L2 state, Directory state, event, count, percentage. Is this correct?

 

Could anyone answer the second question please? Is there a way in Ruby to figure out where most of the latencies come from (like gprof for c code)? I want to understand where the protocol spend the most time stalling.

 

Thank you!

Lei

Dear list,

 

How do I understand the following from Ruby stats?

 

Request vs. System State Profile

NA        L2_NP     M         PUTX      7033       27.2301
NA        L2_NP     MM        PUTX      34         0.13164

NA        L2_OIV    M         PUTX      9          0.0348459

Also, is there a way in Ruby to figure out where most of the latencies come from (like gprof for c code)? I want to understand where the protocol spend the most time stalling.

 

Thanks in advance!
