PRTG Manual: WMI Exchange Transport Queue Sensor

The WMI Exchange Transport Queue sensor monitors the length of transport queues of a Microsoft Exchange Server as of version 2016 via Windows Management Instrumentation (WMI). It shows the same information as in Windows System Monitor perfmon.

For more information and an explanation of transport queue types, see the Knowledge Base: What types of Exchange transport queues are there?

For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
Performance impact	This sensor has a high performance impact. Stay below 200 WMI sensors per probe. Above this number, consider using multiple remote probes for load balancing.
WoW64	This sensor requires WoW64 (Windows 32-bit on Windows 64-bit) for target systems that run Windows Server 2016.
Credentials	This sensor requires credentials for Windows systems.
IPv6	This sensor supports IPv6.
Knowledge Base	Knowledge Base: What types of Exchange transport queues are there?
Hosted probe	You cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device.

Add Sensor

Setting	Description
Transport Queue	Select the transport queues that you want to monitor. PRTG creates one sensor for each transport queue that you select. The available options depend on your Exchange server configuration. PRTG shows all possible queues with names and instance descriptions (if available). For performance reasons, we recommend that you only select necessary items.

Transport Queue

Select the transport queues that you want to monitor. PRTG creates one sensor for each transport queue that you select.

The available options depend on your Exchange server configuration. PRTG shows all possible queues with names and instance descriptions (if available).

For performance reasons, we recommend that you only select necessary items.

Basic Sensor Settings

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

WMI Exchange Transport Queue Specific

Setting	Description
Display Name	The display name that the sensor uses to query data from the target device.
Instance	The instance that the sensor uses to query data from the target device.
WMI Class	The WMI class that the sensor uses to query data from the target device.
Counter	The counter that the sensor uses to query data from the target device.
Time Stamp	The time stamp that the sensor uses to query data from the target device.
Time Frequency	The time frequency that the sensor uses to query data from the target device.
Counter Type	The counter type that the sensor uses to query data from the target device.
Result Handling	Define what PRTG does with the sensor result: Discard result (default): Do not store the sensor result. Store result: Store the sensor result and the last response 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.

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. 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.

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.

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.

Inherited Settings

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.

Channel List

Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
