<p>The <code>snmp</code> sensor platform simple displays the information which are available through the <a href="https://en.wikipedia.org/wiki/Simple_Network_Management_Protocol">Simple Network Management Protocol (SNMP)</a>. SNMP uses a tree-like hierarchy where each node is an object.</p>
|
||
|
||
<p>To enable this sensor in your installation, add the following to your <code>configuration.yaml</code> file:</p>

<p>Configuration variables:</p>
|
||
|
||
<ul>
|
||
<li><strong>host</strong> (<em>Required</em>): The IP address of your host, eg. 192.168.1.32.</li>
|
||
<li><strong>port</strong> (<em>Option</em>): The SNMP port of your host. Defaults to 161.</li>
|
||
<li><strong>name</strong> (<em>Optional</em>): Name of the SNMP sensor.</li>
|
||
<li><strong>community</strong> (<em>Optional</em>): The SNMP community which is set for the device. Most devices have a default community set to to <code>public</code> with read-only permission (which is sufficient).</li>
|
||
<li><strong>baseoid</strong> (<em>Required</em>): The OID where the information is located. It’s advised to use the numerical notation.</li>
|
||
<li><strong>unit_of_measurement</strong> (<em>Optional</em>): Defines the unit of measurement of the sensor, if any.</li>
|
||
</ul>
|
||
|
||
<p>The OIDs may vary on different system because they are vendor-specific. Beside the device’s manual is the <a href="http://www.oid-info.com/">OID Repository</a> a good place to start if you are looking for OIDs. The following OIDs are for the load of a Linux systems.</p>
|
||
|
||
<ul>
|
||
<li>1 minute Load: 1.3.6.1.4.1.2021.10.1.3.1</li>
|
||
<li>5 minute Load: 1.3.6.1.4.1.2021.10.1.3.2</li>
|
||
<li>15 minute Load: 1.3.6.1.4.1.2021.10.1.3.3</li>
|
||
</ul>
|
||
|
||
<p>There is a large amount of tools available to work with SNMP. <code>snmpwalk</code> let you easily retrieve the value of a OID.</p>
