Hi all, Over what time range does "nodetool cfhistograms" operate?
I am using Cassandra 2.0.8.39. I am trying to debug some very high 95th and 99th percentile read latencies in an application that I'm working on. I tried running nodetool cfhistograms to get a flavor for the distribution of read latencies and also to see how many SSTables our reads are using, and I saw different results yesterday versus this morning, so I assume the time window is fairly tight (like an hour or so). I vaguely recall Aaron Morton talking about this during the training course I took at Cassandra Summit, but I cannot find my notes and I think the behavior of the tool with regard to time windows changed from version to version. Thanks! -Clint
