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.

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.
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.

Basic Sensor Settings

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

Exchange Server Data Readings Accessible Using WMI

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 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.

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.

Channel	Description
Active User Count	The number of active users
Average Response Time	The average response time (OWA)
Connection Count	The number of connections
Current Unique Users	The number of current unique users (OWA)
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
RPC Requests Failed	The number of failed RPC requests
RPC Requests Outstanding	The number of outstanding RPC requests
RPC Requests Sent	The number of sent RPC requests
RPC Slow Requests	The number of slow RPC requests
User Count	The number of users
