Hi Kevin,

I'm thinking about writing a module for Ganglia to read the STATS output
from rrdcached

It's also probably worthwhile reading some data from Apache (has anyone
already written such a module for Ganglia?) so that I can compare some
of the following:
- time taken to serve each web request in Ganglia
- queue length
- IO (I already have a module for this)
- memory

Before I start coding around the output of the STATS command, do you
envisage more changes in the imminent future?  Also, do you think it
might be worthwhile storing things like the maximum value of the queue
length between any two STATS queries?
