The \fBinfo\fR function prints the header information from an \s-1RRD\s0 in

Check rrdcreate if you are uncertain about the meaning of the

+.IX Item "--daemon address"
+Address of the rrdcached daemon. If specified, a \f(CW\*(C`flush\*(C'\fR command is sent
+to the server before reading the \s-1RRD\s0 files. This allows \fBrrdtool\fR to return
+fresh data even if the daemon is configured to cache values for a long time.
+For a list of accepted formats, see the \fB\-l\fR option in the rrdcached manual.
