+ =head2 Plugin C<openvpn>
+ 
+ The OpenVPN plugin reads a status file maintained by OpenVPN and gathers
+ traffic statistics about connected clients.
+ 
+ To set up OpenVPN to write to the status file periodically, use the
+ B<--status> option of OpenVPN. Since OpenVPN can write two different formats,
+ you need to set the required format, too. This is done by setting
+ B<--status-version> to B<2>.
+ 
+ So, in a nutshell you need:
+ 
+   openvpn $OTHER_OPTIONS \
+     --status "/var/run/openvpn-status" 10 \
+     --status-version 2
+ 
+ Available options:
+ 
+ =over 4
+ 
+ =item B<StatusFile> I<File>
+ 
+ Specifies the location of the status file.
