Cassandra JMX Bean to monitor the hints

Question

Is there way to monitor the hints in cassandra cluster using the JMX Bean?

I am looking at : http://cassandra.apache.org/doc/latest/operating/metrics.html#hintsservice-metrics and I see the below metric

Metric Name : org.apache.cassandra.metrics.HintedHandOffManager.<MetricName>
JMX MBean : org.apache.cassandra.metrics:type=HintedHandOffManager name=<MetricName>

This is giving the cumulative count of the metrics, but I would like to have the time series trend of hints counts. is it possible to do it via JMX?

I don't think you can achieve this with JMX alone. Other tools/db will be required to store data periodically.

Currently, we are using prometheus + grafana for monitoring Cassandra performance. We have dashboard similar to this
