PRTG Manual: OPC UA Server Status Sensor

Activated server diagnostics on your OPC UA server

• This sensor requires activated diagnostic summary information settings on your OPC UA server to create all diagnostic channels. Without activated diagnostic summary information settings, the sensor can only show the server status and the uptime.

Note that not all vendors support diagnostic summary information.

Valid port

• This sensor requires a valid port.

• Enter 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 very low performance impact.

Lookups

• This sensor uses lookups to determine the status values of one or more channels.

Multi-platform probe

• You can add this sensor to a multi-platform probe.

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:

• Show channels independently (default): Show a graph for each channel.
• Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
  You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

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.

Result Handling

Define what PRTG does with the sensor result:

• Discard result (default): Do not store the sensor result.

• Store result: Store the last sensor result in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

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.

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

Rejected Requests Count

The number of rejected requests

Rejected Session Count

The number of rejected sessions

Security Rejected Requests Count

Server Status

The server status

• Up status: Running, Test
• Warning status: No Configuration, Shut Down, Suspended
• Down status: Communication Fault, Failed, Unknown

This channel is the primary channel by default.
