@amitmund_177224 Depending on the version you're running, you can query:

org.apache.cassandra.metrics:type=Table
  keyspace=<keyspace_name>
  scope=<table_name>
  name=TombstoneScannedHistogram

There's no easy way of determining which MBeans are available since it depends heavily on the version. I recommend you connect via JMX and browse the metrics for type=Table to see what's available. Cheers!

We need help to identify Latency metrics Formula we can use for monitoring metrics like Opscenter. We couldn't figure out MAX Latency. Value that is available in JMX > ClientRequest > WriteLatency > Max (Value) which gets only incremented once new request with Higher value is received. Any solution to this?
