PRTG Manual: SNMP CPU Load Sensor
The SNMP CPU Load sensor monitors the system load via the Simple Network Management Protocol (SNMP).

Consider the following remarks and requirements for this sensor:
Remark |
Description |
|---|---|
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a low performance impact. |
Localhost |
It might not work to query data from a probe device via SNMP (querying localhost, 127.0.0.1, or ::1). Add this device with the IP address that it has in your network and create the sensor on this device instead. |
Basic Sensor Settings
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- cpu
- cpuloadsensor
- snmp
For more information about basic sensor settings, see section Sensor Settings.

Result Handling |
Define what PRTG does with the sensor result:
|
This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.
Sensor Display
Setting |
Description |
|---|---|
Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.
|
Graph Type |
Define how this sensor shows different channels:
|
Stack Unit |
This setting is only visible if you select Stack channels on top of each other above. Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so. |
By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click 
under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Downtime |
In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status |
