Re: read/write request counts and write size of each write

[kurt greaves]

You will need to use jmx to collect write/read related metrics. not aware
of anything that measures write size, but if there isn't it should be
easily measured on your client.
there are quite a few existing solutions for monitoring Cassandra out
there, you should find some easily with a quick search. I believe the
graphite/guarana set up works well.
