 Description   

The statistics of request rates of ptlrpc services in real time is always helpful for us to understand the status of the system. Job Stats(LU-694) might help a lot in some cases. But we might need some other simple, lightweight mechanism to collect the information as an alternate.

The patch that we will push in a few minutes is a simple algorithm which can help to calculate the request rate between different time intervals. It really helps us a lot to monitor how NRS policies act.

LiXi, I saw you abandon the patch because an external tool might be better than this fix. So can I close this ticket?
