---------------------------------------
Fix Version/s: 2.1.12
> Native-Transport-Requests is missing from the nodetool tpstats output in

> Key: CASSANDRA-10044
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10044
> Project: Cassandra
> Issue Type: Bug
> Reporter: Wei Deng
> Priority: Minor
> Labels: patch
> Fix For: 2.1.12

>
> 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.
