WMI Microsoft IIS Application v2 Sensor

The WMI Microsoft IIS Application v2 sensor monitors a Microsoft Internet Information Services (IIS) server via Windows Management Instrumentation (WMI) and the WSMan protocol. It can also monitor applications that use IIS, such as Microsoft SharePoint or Microsoft SQL Server 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
Credentials	This sensor requires credentials for Windows systems.
WSMan	This sensor requires that the parent probe uses WSMan for WMI connections.
Access rights	The user account must be a member of the Remote Management Users group on the target system. The user account must have the following permissions for the WMI namespace CIMv2 and its sub-namespaces on the target system: Enable Account and Remote Enable. The user account must be a member of the local Performance Monitor Users group on the target system.
Windows Compatibility Options	This sensor uses only WSMan Port and Connection Security from the Windows Compatibility Options.
Meta-scan	This sensor uses the meta-scan feature. After sensor creation, some settings might appear for reference purposes only.
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.
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a low performance impact.
Lookups	This sensor uses lookups to determine the status values of one or more channels.
Knowledge Base	For more information on how to set up the necessary access rights, see the Knowledge Base: How can I use a non-administrator Windows account for WMI monitoring via the WSMan protocol?.

Basic Sensor Settings

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

iissensor
wmiiis

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

Specific Sensor Settings

During sensor creation, PRTG performs a meta-scan of the target device and displays all available IIS web service instances in a table. Select the checkbox next to the instance that you want to monitor. PRTG creates one sensor for each instance that you select.

You cannot change the instance that this sensor monitors after sensor creation. If you want to monitor a different instance, create the sensor again.

If you want to monitor the combined values for all IIS web service instances on the target system, select _Total.

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

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.

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].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval. This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance. In a cluster, PRTG stores the result in the PRTG data directory of the master node.

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

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
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 requests that returned a 404 Not Found error
POST Requests	The number of POST requests
Status	The web service status Up status: Running Down status: Stopped Unknown status: Channel Value Not Set This channel is based on uptime. If uptime is 0, the web service is stopped. This channel is the primary channel by default.
Total Bytes	The total number of bytes sent and received by the IIS web service
Uptime	The uptime The sensor only reports uptime when the web service is running. When the web service is stopped, this channel has no value.
