RT provides a diagnostics API which you can run to return information about the state and health of the RT cluster.
This diagnostics report is intended to be viewed by a Support team to troubleshoot problems that arise when access to the RT cluster is not available.
To return the diagnostics you must call an API on the RT supervisor process running in you kubernetes cluster.
You should perform this call on each of the nodes in the RT cluster as each node will return it's own set of diagnostics.
diagnostics REST request against port 6000 of each of the RT nodes in your RT cluster:
RT can only handle one request at a time.
In order to use the API you must port-forward port 6000 of one of the applicable RT pods to their localhost. For example where remote 6000 has been port-forwarded to localhost 6000:
curl http://127.0.0.1:6000/diagnostics > /tmp/diagnostics.json
