By default, the "logfile" plugin writes to a file. The plugin is
activated (with the default settings) as soon as the appropriate
"LoadPlugin" line of the config file has been parsed. So, any messages
that are logged before the "<Plugin logfile>" block has been parsed are
written to the file.

To work around that, you can place the "<Plugin logfile>" block right
after the "LoadPlugin logfile" line.

Now, the question arises, if this should somehow be handled by collectd.
This could be achieved by parsing all of the config file before loading
or activating any plugins. Imho there is no real need to have any
side-effects while parsing the config file. Any thoughts? Florian?

HTH,
Sebastian
