Hello Carl, Here is a message I sent to my team a few months ago. I hope this will be helpful to you and more people around :). It might not be exhaustive and we were moving from C*2.1 to C*3+ in this case, thus skipping C*2.2, but C*2.2 is similar to C*3.0 if I remember correctly in terms of metrics. Here it is for what it's worth:
Quite a few things changed between metric reporter in C* 2.1 and C*3.0. - ColumnFamily --> Table - XXpercentile --> pXX - 1MinuteRate --> m1_rate - metric name before KS and Table names and some other changes of this kind. - ^ aggregations / aliases indexes changed because of this (using graphite for example) ^ - ‘.value’ is not appended in the metric name anymore for gauges, nothing instead. For example (graphite): From aliasByNode(averageSeriesWithWildcards(cassandra.$env.$dc.$host.org.apache.cassandra.metrics.ColumnFamily.$ks.$table.ReadLatency.95percentile, 2, 3), 1, 7, 8, 9) to aliasByNode(averageSeriesWithWildcards(cassandra.$env.$dc.$host.org.apache.cassandra.metrics.Table.ReadLatency.$ks.$table.p95, 2, 3), 1, 8, 9, 10) C*heers, ----------------------- Alain Rodriguez - @arodream - al...@thelastpickle.com France / Spain The Last Pickle - Apache Cassandra Consulting http://www.thelastpickle.com Le ven. 28 sept. 2018 à 20:38, Carl Mueller <carl.muel...@smartthings.com.invalid> a écrit : > VERY NICE!
