PRTG Manual: PerfCounter IIS Application Pool Sensor
The PerfCounter IIS Application Pool sensor monitors a Microsoft Internet Information Services (IIS) application pool via Windows performance counters.
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Windows version |
This sensor requires at least Windows Server 2008 R2 on the probe system (on every cluster node, if on a cluster probe). |
IIS version 7.5 |
This sensor requires as of Microsoft IIS 7.5 on the target system. |
Remote Registry Windows service |
This sensor requires that the Remote Registry Windows service runs on the target system. If this service does not run, a connection via performance counters is not possible. To enable the service, log in to the respective system and open the services manager (for example, via services.msc). In the list, find the respective service and set its Start Type to Automatic. |
Credentials |
This sensor requires credentials for Windows systems. We recommend that you 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 system. Otherwise, a connection via performance counters is not possible. However, WMI connections might still work. The user account must be a member of the Performance Monitor Users user group on the target system. |
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. |
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. |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- pciisapppool
- performancecounter
For more information about basic sensor settings, see section Sensor Settings.

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:
|
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. |
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.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Application Pool State |
The overall application pool status
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 |
Worker Process Failures |

Worker Process Ping Failures |
The number of failures in worker process pings |
Worker Process Shutdown Failures |
The number of failures in worker process shutdowns |
Worker Process Startup Failures |
The number of failures in worker process startups |
Worker Processes |
The number of worker processes |
