Thanks but this is an internal only application.

I haven't tried cacti, but I'm using CloudKick as an external service for monitoring Cassandra.  It's super easy to get setup.  Happy to share my setup if that'd help.

It doesn't currently monitor JMX information, but it does offer some basic checks like thread pool and column family stats -

Setting up cacti is easy, the second time, and third time :)
As for cassandra-cacti-m6 (i am the author). Unfortunately, I have
been fighting the jmx switcharo battle for about 3 years now

In a nutshell there is ALWAYS work involved. First, is because as you
noticed attributes change/remove/add/renamed. Second it takes a human
to logically group things together. For example, if you have two items
"cache hits" and "cache misses". You really do not want two separate
graphs that will scale independently. You want one slick stack graph,
with nice colors, and you want a CDEF to calculate the cache hit
percentage by dividing one into the other and show that at the bottom.

If you want to have a 7.0 branch to cassandra-cacti-m6 I would love
the help. We are not on 7.0 yet so I have not had the time just to go
out and make graphs for a version we are not using yet :) but if you
come up with patches they are happily accepted.
