[collectd] problem with importing collectd python module

Hi Pawel,

are you loading the plugin from collectd's config file as described in
its documentation [1]?
Python scripts importing the collectd module are meant to be run by a
Python interpreter included in collectd (by loading and configuring the
"Python" plugin in collectd.conf) to avoid the overhead of running
multiple Python interpreters. Running those scripts manually from the
commandline won't work.
To add to the confusion, there's also a Python wrapper around collectd's
Unix socket interface, but that one isn't used here.

If so please write with file it is because I couldn't find it. If it's not included in collectd source code from where can I get it? In collectd python plugin documentation there is example with "import collectd" which is loading collectd python module.
