PRTG Manual: WMI Exchange Server Sensor

Performance Counter

Select the performance counters of the Exchange server that you want to monitor. PRTG creates one sensor for each performance counter that you select.

Enable check boxes in front of the respective lines to select the items. Use the check box in the table header to select all items or to cancel the selection. In large tables, use the search function in the upper-right corner.

The available options depend on your Exchange server configuration. PRTG shows all possible performance counters with the name and instance description (if available).

You might be able to select 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.

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:

• wmiexchangeserversensor

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 ().

Display Name

Shows the display name that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Instance

Shows the instance that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

WMI Class

Shows the WMI class that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Counter

Shows the counter that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Time Stamp

Shows the time stamp that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Time Frequency

Shows the time frequency that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Counter Type

Shows the counter type that the sensor uses to query data from the target device.

PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

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.

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
