5 rrdcached - Data caching daemon for rrdtool
9 B<rrdcached> [B<-l> I<address>] [B<-w> I<timeout>] [B<-f> I<timeout>]
13 B<rrdcached> is a daemon that receives updates to existing RRD files,
14 accumulates them and, if enough have been received or a defined time has
15 passed, writes the updates to the RRD file. A I<flush> command may be used to
16 force writing of values to disk, so that graphing facilities and similar can
17 work with up-to-date data.
23 =item B<-l> I<address>
25 Tells the daemon to bind to I<address> and accept incoming connections on that
26 socket. If I<address> begins with C<unix:>, everthing following that prefix is
27 interpreted as the path to a UNIX domain socket. Otherwise the address or node
28 name are resolved using L<getaddrinfo(3)>.
30 =item B<-w> I<timeout>
32 Data is written to disk every I<timeout> seconds.
34 =item B<-f> I<timeout>
36 Every I<timeout> seconds the entire cache is searched for old values which are
37 written to disk. This only concerns files to which updates have stopped, so
38 setting this to a high value, such as 3600 seconds, is acceptable in most
49 Base directory is currently hard coded. The daemon will chdir to C</tmp/>.
