<p>In this section you will learn how to get general systeminformation data. We will also cover the "get-all" functions to get all data at once.</p>
|
|
<p>For function reference and examples we assume, that we imported <span class="code">systeminformation</span> as follows:</p>
|
|
<pre><code class="js">const si = require('systeminformation');</code></pre>
|
|
<h2>Lib-Version and Time/Timezone</h2>
|
|
<p>The first two functions just gibe back system information library version and time/timezone information of your machine:</p>

<p>Keep in mind, that there is another function <span class="code">si.versions()</span> that will return versions of other system libraries and software packages</p>
|
|
<h2>Get All At Once</h2>
|
|
<p>The following three functions <span class="code">si.getStaticData()</span>, <span class="code">si.getDynamicData()</span> and <span class="code">si.getAllData()</span> will return most of the available data in a single result object:</p>

|
<p><strong>Static data</strong> is all hardware related (or more or less constant) data like system, baseboard, bios, OS, versions, cpu, network interfces, memory and disk layout</p>
|
|
<p><strong>Dynamic data</strong> will return user, cpu-speed, load, processes, services, temperature, file system, network and disk stats, ... </p>
|
|
<p>As not all funtions are supported in each operating system the result object might be different in each OS.</p>
|
|
<p><strong>ATTENTION</strong>: Use this only if you really need ALL information. Especially on Windows this can take really long (up to 20 seconds) because the underlying <span class="code">WMIC</span> command is very slow when using it the first time.</p>
