Subject Measuring load in Cassandra
Date Thu, 26 Nov 2009 00:06:43 GMT
Hi all

We are trying to measure the load on cassandra nodes in production.
Looking at the jconsole interface, we see a few attributes like:
ReadCount, WriteCount, ReadLatency, WriteLatency.

>From what I have observed of these numbers, ReadCount might be 15 one
second but 14 the next one, so I can't really understand what it is
trying to measure. Is it cummulative reads on this node, or reads per
Also are these numbers accurate or are they broken?
