laneser kuo closed CASSANDRA-4653. ---------------------------------- Thanks reply, after taking more time to read code, the latency data comes from addNano , which is 10^-9 seconds, then histograms store data in micro seconds, which is 10^-6 seconds, and cfstats shows milliseconds, which is 10^-3 seconds. > nodetool cfstats Lantecy unit is wrong , it should be sec (seconds) instead > of ms (micro seconds) > ------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-4653 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4653 > Project: Cassandra > Issue Type: Bug > Components: Tools > Reporter: laneser kuo > Priority: Trivial > Attachments: mstosec.txt > > > I was mislead by the nodetool cfstats Read Latency and Write Latency data. > Until I read the source code, it should display sec instead of ms. > for example: > outs.println("\t\tRead Latency: " + String.format("%01.3f", > cfstore.getRecentReadLatencyMicros() / 1000) + " ms."); -- This message is automatically generated by JIRA.
