You want the count attribute of the client-request latency histogram (closest thing to documentation here: http://cassandra.apache.org/doc/latest/operating/metrics.html#client-request-metrics). For the scope, there are more request-types than are listed in the documentation; For each CL there is a read/write scope, ala (Read|Write)-(LOCAL-QUORUM,LOCAL-ONE,QUORUM,ONE,...). An example dashboard: https://grafana.wikimedia.org/dashboard/db/cassandra-client-request?panelId=1&fullscreen&orgId=1&var-datasource=eqiad%20prometheus%2Fservices&var-cluster=restbase&var-node=All&var-quantile=99p Note: This graph suppresses series with a rate of zero for the graph time-span, so you won't see all possible request-types. -- Eric Evans john.eric.ev...@gmail.com
