Description
Ambari Grafana metrics appear to have another bug in HBase - Home -> Num Requests - Total.
writeRequestCount and totalRequestCount are about the same but readRequestCount is consistently triple that of totalRequestCount which cannot possibly be true...
totalRequestCount should == writeRequestCount + readRequestCount, but this is not the case.
It looks like this may be due to multi requests being counted only once, seeĀ HBASE-18469.
This is not at all intuitive, it would have been better to have made totalRequestCount == writeRequestCount + readRequestCount and made a new metric to count multi requests as a single request.
