<p>The <code class="highlighter-rouge">systemmonitor</code> sensor platform allows you to monitor disk usage, memory usage, CPU usage, and running processes. This platform has superseded the process component which is now considered deprecated.</p>
|
||
<p>To add this platform to your installation, add the following to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
|
||
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>
|

<h2><a class="title-link" name="windows-specific" href="#windows-specific"></a> Windows specific</h2>
|

<p>When running this platform on Microsoft Windows, Typically, the default interface would be called <code class="highlighter-rouge">Local Area Connection</code>, so your configuration might look like:</p>
|
||
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="s">sensor</span><span class="pi">:</span>

|
||
</code></pre>
|
||
</div>
|
||
<p>If you need to use some other interface, open a command line prompt and type <code class="highlighter-rouge">ipconfig</code> to list all interface names. For example a wireless connection output from <code class="highlighter-rouge">ifconfig</code> might look like:</p>
|
||
<div class="language-bash highlighter-rouge"><pre class="highlight"><code>Wireless LAN adapter Wireless Network Connection:
