PRTG Manual: Windows IIS Application Sensor

The Windows IIS Application sensor monitors a Microsoft Internet Information Services (IIS) server via Windows Management Instrumentation (WMI). It can also monitor applications that use IIS, such as Microsoft SharePoint or Microsoft Reporting Services (SSRS).

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
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.
Performance counters	The sensor cannot return data for the channels Status, Uptime, and Total when using performance counters. We recommend that you use WMI only (default) as Preferred Data Source in the Windows Compatibility Options of the parent device.
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a medium performance impact.
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:

wmiiis

For more information about basic sensor settings, see section Sensor Settings.

Windows Internet Information Services

Setting	Description
Instance	The unique instance name of the web service that this sensor monitors.

Debug Options

Setting	Description
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 name is Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval. In a cluster, PRTG stores the result in the PRTG data directory of the master node.

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 name is Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites this file 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
Anonymous Users	The number of anonymous users
Bytes Received	The number of bytes received
Bytes Sent	The number of bytes sent This channel is the primary channel by default.
CGI Requests	The number of CGI requests
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.
Files Received	The number of files received
Files Sent	The number of files sent
Get Requests	The number of GET requests
Known Users	The number of known users
Not Found Errors	The number of not found errors
Post Requests	The number of POST requests
Status	The web service status Up status: Running Down status: Stopped
Total	The total
Uptime	The uptime
