-
-RRDd - Data caching daemon for rrdtool
-
-=head1 SYNOPSIS
-
-B<rrdd> [B<-l> I<address>] [B<-w> I<timeout>] [B<-f> I<timeout>]
-
-=head1 DESCRIPTION
-
-RRDd is a daemon that receives updates to existing RRD files, accumulates them
-and, if enough have been received or a defined time has passed, writes the
-updates to the RRD file. A I<flush> command may be used to force writing of
-values to disk, so that graphing facilities and similar can work with
-up-to-date data.

-=over 4
-
-=item B<-l> I<address>
-
-Tells the daemon to bind to I<address> and accept incoming connections on that
-socket. If I<address> begins with C<unix:>, everthing following that prefix is
-interpreted as the path to a UNIX domain socket. Otherwise the address or node
-name are resolved using L<getaddrinfo(3)>.
-
-=item B<-w> I<timeout>
-
-Data is written to disk every I<timeout> seconds.
-
-=item B<-f> I<timeout>
-
-Every I<timeout> seconds the entire cache is searched for old values which are
-written to disk. This only concerns files to which updates have stopped, so
-setting this to a high value, such as 3600 seconds, is acceptable in most
-cases.
