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.

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

Sensor in Other Languages

  • Dutch: WMI Exchange Transport Wachtrij
  • French: Exchange file d'attente de transport (WMI)
  • German: WMI Exchange Transportwarteschlange
  • Japanese: WMI Exchange 転送キュー
  • Portuguese: Fila de transporte Exchange (WMI)
  • Russian: Очередь транспорта WMI Exchange
  • Simplified Chinese: WMI Exchange 传输队列
  • Spanish: Cola de transporte Exchange (WMI)

Remarks

  • 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.
  • This sensor requires WoW64 (Windows 32-bit on Windows 64-bit) for target systems that run Windows Server 2016.
  • This sensor requires credentials for Windows systems in the settings of the parent device.
  • This sensor supports IPv6.

i_podYou 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

WMI Exchange Transport Queue Specific

Setting

Description

Transport Queue

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

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

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

Setting

Description

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.

i_round_blueIf 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

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

i_round_blueThis 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.

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

i_round_blueFor 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:

  • wmiexchangeservertransportqueuesensor

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 (i_priority_1) to the highest priority (i_priority_5).

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 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.

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

Description

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.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary 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.
    i_round_redYou 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. 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.

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 b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

Schedules, Dependencies, and Maintenance Window

i_round_blueYou cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
