+collectd can operate in four different operating modes. The modes are described

 The simplest mode is the so called B<local mode>. Data is collected locally and
 written in RRD files that reside in I<DataDir>. This is the default mode when
 collectd is linked against C<librrd>.
 
-The other modes, B<client mode> and B<server mode>, are used to send data over

 If started in B<server mode> the daemon will listen on one or more interfaces
 and write the data it receives to RRD files. No data is collected locally.
