------------------------------------------
Summary: Nodetool info should report on new networking_cache
Key: CASSANDRA-18400
URL: https://issues.apache.org/jira/browse/CASSANDRA-18400
Project: Cassandra
Issue Type: Improvement
Reporter: Brad Schoening
CASSANDRA-15229 separated the chunk and network cache, creating a new
network_cache_size parameter.
However, *nodetool info* does not report the in-use size of this cache or a hit
ratio as it does for key, row, counter and chunk cache.

However, when its full, it will be logged:
