PRTG Manual: WSUS Statistics Sensor

.NET 4.7.2 or later

This sensor requires .NET 4.7.2 or later to be installed on the probe system (on every cluster node, if on a cluster probe).

If the framework is missing, you cannot create this sensor.

For more information, see the Knowledge Base: Which .NET version does PRTG require?

Windows credentials

This sensor requires credentials for Windows systems in the settings of the parent device. Preferably, use Windows domain credentials.

If you use local credentials, make sure that the same Windows user accounts (with the same user name and password) exist on both the probe system and the target computer. Otherwise, the sensor cannot correctly connect.

WSUS 3.0 Administration Console

For this sensor to work, the Microsoft WSUS 3.0 Administration Console must be installed on the probe system. In a cluster, it must be installed on every cluster node.

Sensor Name

Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.

If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?

Parent Tags

Shows tags that the sensor inherits from its parent device, parent group, and parent probe.

This setting is for your information only. You cannot change it.

Tags

Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.

It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).

For performance reasons, it can take some minutes until you can filter for new tags that you added.

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

▪ptfsensor

Priority

Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority ().

WSUS Server Port

Enter the number of the port the WSUS server service runs on. The default value is 8530. Enter an integer.

Connection Security

Define if you want to use Secure Sockets Layer (SSL)/Transport Layer Security (TLS) for the connection to the WSUS server or if you prefer unsecured connections:

▪Use SSL/TLS

▪Do not use connection security

If you want to use SSL/TLS, you must configure the WSUS server accordingly. For details, see the Knowledge Base: Can I encrypt connections to my WSUS server?

Result Handling

Define what PRTG does with the sensor result:

▪Discard result: 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 names are Result of Sensor [ID].txt and Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.

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

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed 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 different channels are shown for this sensor:

▪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 enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are stacked 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.
