You can do sampling of tracing on a table to avoid some of the overhead.

Hi Nicolas,
Thank you very much for the response.
I am looking into something with a smaller time frame than a minute.
Tracing is a good way to get these information but it introduces a huge
overhead in the system that I'd like to avoid it.
Thanks

Hi,
With
org.apache.cassandra.metrics:type=ClientRequest,scope=Read,name=Latency and
OneMinuteRate you can have such a metrics
As for the state of the request with regards to other node I do no think
you can have that IMHO with JMX (this is available using TRACING per
request)

Hello!
There is any way to know how many queries a node is currently serving
through JMX(or other tools)? And the state of the request so, for example,
if the request is waiting for data from another node?
Thanks
Salvatore
