 Writing a Python module is very simple. You just need to write it following a template and put the resulting Python module (.py) in /usr/lib(64)/ganglia/python_modules. A corresponding Python Configuration (.pyconf) file needs to reside in /etc/ganglia/conf.d/.
+
+If your Python module needs to access certain files on the server, keep in mind that the module will be executed as the user which runs `gmond`.  In other words, if `gmond` runs as user `nobody` then your module will also run as `nobody`. So make sure that the user which runs `gmond` has the correct permissions to access the files in question.
 
 The Ganglia distribution comes with an example Python module in /usr/lib(64)/ganglia/python_modules/example.py. Alternatively, this file is also viewable from our SVN repository: http://ganglia.svn.sourceforge.net/viewvc/ganglia/branches/monitor-core-3.1/gmond/python_modules/example/example.py?view=markup
