Hello,
I'm using Cassandra 3.11.1 and trying to change the name of
cassandra.log(which is generate during startup of Cassandra) file. Can

System.log/debug.log located in logback.xml but not the Cassandra.log.
Thanks
Hi
Is there a way to calculate or mesaure the read/ sec and write / sec in
cassandra?
I have prometheus tool to capture metrics it has read count ans write count
not sure if its relevant to the clusster capacity to measure the read n
write sec processing.
Can we the see “nodetool tablestats” for the biggest table as well.

Rahul,
Those partitions are tiny. Could you give us the table histograms for the
biggest tables.
