PRTG Manual: OPC UA Custom Sensor
The OPC UA Custom sensor monitors up to ten numeric values returned by specific OPC Unified Architecture (OPC UA) NodeIDs.
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 |
---|---|
Valid port |
This sensor requires a valid port for the connection to the OPC UA server. |
Credentials |
This sensor requires credentials for OPC UA in the settings of the parent device. |
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a low performance impact. |
Lookups |
This sensor uses lookups to determine the status values of one or more channels. |
Scanning interval |
The minimum scanning interval of this sensor is 30 seconds. |
Multi-platform probe |
You can add this sensor to a multi-platform probe. |

Channel #1 – #10 Naming Method |
Select the naming method for the channels of the sensor:
You can change this value later in the channel settings of this sensor. |
Channel #1 - #10 Unit |
Enter the unit for the numeric value that this sensor monitors. You can change this value later in the channel settings of this sensor. |
Channel #1 – #10 NodeID |
Enter the NodeID from which you want to receive numeric data. A NodeID looks like this, for example: ns=1;i=1234, ns=2;s=test_one, or 'ns=1;s=test_one'[4]. The sensor supports string identifiers, numeric identifiers, and array syntaxes. |
Channel #2 - #10 |
You can define up to 10 channels. You must define at least one channel, so you see all available settings for Channel #1. Specify how to handle all other possible channels:
It is not possible to enable or disable channels after sensor creation. |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- opcua
- opcuacustom
For more information about basic sensor settings, see section Sensor Settings.

Sensor Message NodeID |
Optionally enter the NodeID from which you want to receive a string that the sensor shows as sensor message. A NodeID looks like this, for example: ns=1;i=1234, ns=2;s=test_one, or 'ns=1;s=test_one'[4]. The sensor supports string identifiers, numeric identifiers, and array syntaxes. The sensor only shows the received string if the sensor is in the Up status. If the sensor enters the Down status, the sensor message shows the error message instead. |
Channel #x NodeID |
The NodeID from which the sensor receives numeric data. A NodeID looks like this, for example: ns=1;i=1234, ns=2;s=test_one, or 'ns=1;s=test_one'[4]. The sensor supports string identifiers, numeric identifiers, and array syntaxes. |

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. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab. |
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. |

Description |
---|---|
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. In a cluster, PRTG stores the result in the PRTG data directory of the master node. |
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 |
