Subject [jira] Commented: (CASSANDRA-1491) Allow queries to the snitch via JMX
Date Wed, 22 Sep 2010 18:58:34 GMT


Nirmal Ranganathan commented on CASSANDRA-1491:

There's no clean way to have one mbean without adding getScores(), which is specific for dynamic
snitch to IEndPointSnitch. I'll upload a patch with that though.

> The Ripcord team wishes upon a star that there was a way to make queries to a cluster's
Snitch using JMX or the cassandra API.  As in, exposing the getRack() and getDatacenter()
calls.  This would allow our monitoring and control software to have a similar idea about
"where" nodes are as the cluster itself, and improve visualization.
