Subject Monitoring Tomcat - Delta Values

All,

In Rainer's talk at ApacheCon [1], he mentioned a number of
JMX-inspectable values that weren't terribly informative on their own
(e.g. number of total requests processed by a connector) but were
interesting when observed as deltas of their previous value.

I was wondering if anyone could recommend an existing tool to capture
that data, compute the deltas, etc. or if folks just roll their own?
This kind of thing could be very useful to lots of users and I was
thinking of linking to an existing tool on the FAQ/Monitoring wiki
page or writing such a tool and posting it there (similar to the
check_jmxproxy Perl script I put up there for use with Nagios).

Ultimately, I'm thinking that it might be nice to have a single script
that can (given some configuration) take a JMX snapshot of Tomcat
(probably through a filter that grabs only those values of interest),
record the values somewhere (e.g. bdb, rrd, etc.), compute deltas
where appropriate, and then publish to a monitoring tool (e.g. Nagios).

As it stands in my environments, I typically have 4-6 check_jmxproxy
processes that all take a single sample via JMXProxyServlet on-demand
from Nagios. Though the scripts aren't terribly CPU- or
memory-intensive, it seems like things could be streamlined with a
tool that can take care of multiple samples and also provide this
additional capability.

Any ideas or suggestions? I'm motivated enough to build this stuff
myself if such a tool does not yet exist.

Thanks,
- -chris
