------------------------------------------

Thanks for the report and the patch; I've made a note on CASSANDRA-10018 to see if these can all be dealt with together.

> It appears that in Cassandra 2.1 the output of "nodetool tpstats" has changed a bit, and Native-Transport-Requests is removed. This is a useful piece of statistics information to understand the pressure at the coordinator. Even though people can still use JMX or metrics reporter to get the same information, it is not as convenient as before (in Cassandra 2.0 this is exposed through tpstats).
> Looking at the code https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/tools/NodeProbe.java#L1369-L1371, this appears to be caused by some restructure in the JMX metrics, and can be easily patched by adding "org.apache.cassandra.transport:type=*" into the list of thread pools we print out.
> I understand Sam filed another JIRA https://issues.apache.org/jira/browse/CASSANDRA-10018 just a few days ago. However, that is for versions 2.2 and beyond. The patch here is to specifically address a missing information in Cassandra 2.1.
