PRTG Manual: WMI Exchange Server Sensor
The WMI Exchange Server sensor monitors a Microsoft Exchange Server as of version 2016 via Windows Management Instrumentation (WMI).
You might be able to monitor aspects regarding:
- SMTP Server: Queue Lengths
- MSExchangeIS Mailbox: Queue Sizes, Delivery Times, Operations, Messages
- MSExchangeIS Public: Queue Sizes, Delivery Times, Operations, Messages
- MSExchangeIS: Packets, Operations, Clients, Latency, Requests, Users
- MSExchange RPC Client Access: Active User Count, User Count, Connection Count
- MSExchange OWA: Current Unique Users, Average Response Time
Depending on your Exchange server version, not all counters might be available.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.
- Dutch: WMI Exchange Server
- French: Exchange serveur (WMI)
- German: WMI Exchange-Server
- Japanese: WMI Exchange サーバー
- Portuguese: Servidor Exchange (WMI)
- Russian: WMI Exchange Server

- 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.
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.

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.
|
Parent Tags |
The tags that the sensor inherits from its parent device, parent group, and parent probe.
|
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.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
|
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 ( |

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. |

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.
|
Graph Type |
Define how different channels are shown for this sensor:
|
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. |
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.
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You 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.
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window (default).
For more information, see section Root Group Settings, section Access Rights.
Which channel units are available depends on the sensor type and the available parameters. If no configurable channels are available, this field shows No configurable channels.
For more information, see section Root Group Settings, section Channel Unit Configuration.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
