The daemon will put the files to the head of the update queue so they are written "soon". The status will be returned only after the files' pending updates have been written to disk.</p> <dl> <dt id="filename"><i>filename</i></dt> <dd> <p>The name(s) of the <b>RRD</b> file(s) that are to be written to disk.</p> </dd> <dt id="daemon--d-address"><b>--daemon</b>|<b>-d</b> <i>address</i></dt> <dd> <p>Address of the <a href="./rrdcached.html">rrdcached</a> daemon.
