I'm not sure how you're getting metrics from Cassandra to Prometheus,
or if you're using the JMX exporter agent, how your configuration
might be rewriting metric names, so I'll just refer you to the
document of JMX metrics in the hope you can infer what you need from


There are metrics that can tell you the number of queries being made,
broken down by request type:


Use table metrics if you want the rates of reads/writes against the
data that those client requests translate into:


Another measure of throughput you might want to monitor is compaction.
For example, the rate of compactions, and the number of bytes
compacted, are both of interest.  Pending compactions can give you an
idea of saturation.


Hope this helps.
