Does enabling probabilistic tracing in Cassandra (3.11.2) stops some internal work?
When I set 0 probability back, it goes up.

Tracing does not prevent tasks from operating but since tracing is a very expensive operation, it can significantly impact the performance of your cluster.
Depending on how busy your cluster is, exercise a lot of caution when enabling probabilistic tracing. Only enable it on one node at a time and start with a very low value, say 0.1% (probability value of
Monitor the performance of the node for at least 5-10 minutes. Only increase the probability in very small increments if absolutely necessary.
If you see any negative effects, disable tracing immediately. We recommend that you don't leave tracing on unless you are actively monitoring the performance of your cluster. Cheers!
