PRTG Manual: RADIUS v2 Sensor
The RADIUS v2 sensor monitors a Remote Authentication Dial-In User Service (RADIUS) server according to RFC 2865.
The sensor tries to authenticate itself against the server. If authentication fails, the sensor shows the Down status.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Performance impact |
This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe. |
.NET 4.7.2 or later |
This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node.
|
Plain text authentication |
This sensor only supports plain text authentication (Password Authentication Protocol (PAP)). |
IPv4 |
This sensor only supports IPv4. |
Lookups |
This sensor uses lookups to determine the status values of one or more channels. |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- radiussensor
For more information about basic sensor settings, see section Sensor Settings.
Setting |
Description |
---|---|
Timeout (Sec.) |
Enter a timeout in seconds for the request. Enter an integer. The maximum timeout value is 900 seconds (15 minutes).
|
User Name |
Enter the user name for the authentication against the RADIUS server. Enter a string. |
Password |
Enter the password for the authentication between the client (the probe system) and the RADIUS server. Enter a string. |
Shared Secret |
Enter the shared secret for the authentication between the authenticator (the probe system) and the RADIUS server. Enter a string. |
Port |
Enter the number of the port for the connection to the RADIUS server. The default value is 1812. Enter an integer. |
NAS Identification |
Define how to identify the network access server (NAS):
|
NAS IP Address |
This setting is only visible if you select Use NAS IP address (default) above. Enter a valid IP address for the NAS that originates the access request. |
NAS Identifier |
This setting is only visible if you select Use NAS identifier above. Enter an identifier for the NAS that originates the access request. |
Result Handling |
Define what PRTG does with the sensor result:
|

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.
