Dear GPFSUG, In GPFS v4, is there a way to track each request from their starting point (i.e. client node) to the back-end storage ? I’d like to see all timings, especially those related to the Infiniband layer (i.e. verbs).
I remember that Sven Oehme told us (in the last GPFS UG in London) about new performance measurements in GPFS v4. I have tried the new mmdiag --rpc command but honestly I was not able to understand the result properly. I also tried the dstat python plugin, but I didn’t see any new timings related to Infiniband. So I’m wondering wether or not I was dreaming somehow during the meeting ?!? Can someone enlighten me on this ? Many thanks.
