Remarks
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.
Detailed Requirements
|
|
IIS version 7.5 or later
|
To monitor IIS application pools, this sensor needs IIS version 7.5 or later or later to be installed on the target system.
|
Windows credentials
|
This sensor requires credentials for Windows systems in the settings of the parent device. Preferably, use Windows domain credentials.
If you use local credentials, make sure that the same Windows user accounts (with the same user name and password) exist on both the probe system and the target computer. Otherwise, a connection via performance counters is not possible. However, WMI connections might still work.
The user account has to be a member of the Performance Monitor Users user group on the target system.
|
Windows version
|
For this sensor to work with Windows performance counters, make sure that a Windows Server 2008 R2 or later or later is installed on the probe system (on every cluster node, if on a cluster probe).
|
Remote Registry Windows service
|
For this sensor to work with Windows performance counters, make sure that the Remote Registry Windows service runs on the target computer. If this service does not run, a connection via performance counters is not possible.
To enable the service, log in to the respective computer and open the services manager (for example, via services.msc). In the list, find the respective service and set its Start Type to Automatic.
|
Add Sensor
The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the settings that are required to create the sensor. You can change nearly all settings on the sensor's Settings tab after creation.
The settings that you select in the Add Sensor dialog are valid for all sensors that you create when you finish the dialog.
IIS Application Pool Specific

|
Application Pools
|
Select the application pools that you want to monitor. PRTG creates one sensor for each application pool 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.

Basic Sensor Settings
Click the Settings tab of a sensor to change its settings.
Basic Sensor Settings
|
|
Sensor Name
|
Enter a name to identify the sensor.
|
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:
- performancecounter
- pciisapppool
|
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 ().

|
Application Pools
|
Shows the name of the application pool that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

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.
|
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.
Scanning Interval
Scanning Interval
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.
Schedules, Dependencies, and Maintenance Window
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window.
Access Rights
Access Rights
For more information, see section Root Group Settings, section Access Rights.
Channel Unit Configuration
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.
Channel Unit Configuration
For more information, see section Root Group Settings, section Channel Unit Configuration.
Channel List
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

|
Application Pool State
|
The overall status of the application pool
- Up status: Running, Unavailable for Total
- Warning status: Initialized, Shutdown Pending
- Down status: Delete Pending, Stopped, Stopping, Unavailable, Uninitialized
This channel is the primary channel by default.
|
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 in percent.

Worker Process Failures
|
The number of failures in worker processes per second
|
Worker Process Ping Failures
|
The number of failures in worker process pings per second
