----------------------------------------
Summary: Expose sizes of off-heap data structures via JMX and
`nodetool info`
Key: CASSANDRA-7767
URL: https://issues.apache.org/jira/browse/CASSANDRA-7767
Project: Cassandra
Issue Type: New Feature
Reporter: J.B. Langston
It would be very helpful for troubleshooting memory consumption to know the
individual sizes of off-heap data structures such as bloom filters, index
summaries, compression metadata, etc. Can we expose this over JMX? Also, since
`nodetool info` already shows size of heap, key cache, etc. it seems like a
natural place to show this.
