Hi, I want to profile the # of disk access (both random and sequential) issued from HBase (into HDFS). For disk reads, I have tried use blockCacheMissCount, which seems working. But is it the correct way for reads (I can't confirmed it from HBase documents)?
For disk writes, I can't find any metrics in HBase. How should one get disk writes in HBase? Besides, it's best if I can obtain separate numbers regarding to random access and sequential access. Thanks in advance. Regards, Yun
