Hmm... I appreciate it if anybody can point me how to measure server side Get/Scan time... Thanks!

Hi I am using YCSB to measure the performance of some complex Get/Scan, i.e., with some filters. I found that I got weird high latency from YCSB client but both HBase server and YCSB client are NOT saturated (in terms of network, I/O, CPU). So I want to measure the server time a single Get/Scan takes. Is there a way to do it? From the documentation it seems that RPC logging is a place to look but the semantics of the logging is not well-documented so I wonder 1) if RPC logging is the right approach and 2) how I can interpret it correctly. Thanks! Best Regards, Wei
