<h1 id="NAME">NAME</h1>

<p>rrdflushcached - Flush the values for a specific RRD file from memory.</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<p><b>rrdtool</b> <b>flushcached</b> <span style="white-space: nowrap;">[<b>--daemon</b>|<b>-d</b> <i>address</i>]</span> <i>filename</i> [<i>filename</i> ...]</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>The <b>flushcached</b> function connects to <a href="./rrdcached.html">rrdcached</a>, the RRD caching daemon, and issues a &quot;flush&quot; command for the given files. The daemon will put the files to the head of the update queue so they are written &quot;soon&quot;. The status will be returned only after the files&#39; 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. If not specified, the RRDCACHED_ADDRESS environment variable must be set (see below). For a list of accepted formats, see the <b>-l</b> option in the <a href="./rrdcached.html">rrdcached</a> manual.</p>

<pre><code>rrdtool flushcached --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd</code></pre>

</dd>
</dl>

<h1 id="ENVIRONMENT-VARIABLES">ENVIRONMENT VARIABLES</h1>

<p>The following environment variables may be used to change the behavior of <code>rrdtool&nbsp;flushcached</code>:</p>

<dl>

<dt id="RRDCACHED_ADDRESS"><b>RRDCACHED_ADDRESS</b></dt>
<dd>

<p>If this environment variable is set it will have the same effect as specifying the <code>--daemon</code> option on the command line. If both are present, the command line argument takes precedence.</p>

</dd>
</dl>
