You need modpython.conf to include any .pyconf's not gmond.conf
itself. Change the include mysqld.pyconf to:
include ('/etc/ganglia/conf.d/*.conf')
then in /etc/ganglia/conf.d/modpython.conf you should have yet another include:
grep conf /etc/ganglia/conf.d/modpython.conf
include ('/etc/ganglia/conf.d/*.pyconf')
it's important that modpython loads your modules, not gmond itself.
(i think i'm describing this correctly)
