Remarks

  • This sensor requires Microsoft Internet Information Services (IIS) version 7.5 or later on the target system.
  • This sensor requires credentials for Windows systems in the settings of the parent device.
  • This sensor requires that the Remote Registry Windows service runs on the target computer.
  • This sensor requires Windows Server 2008 R2 or later on the probe system.
  • This sensor supports the IPv6 protocol.
  • This sensor has a low performance impact.
  • This sensor uses lookups to determine the status values of one or more channels. This means that possible states are defined in a lookup file. You can change the behavior of a channel by editing the lookup file that the channel uses. For details, see section Define Lookups.

i_podYou 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

Requirement

Description

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.

i_round_redIf 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.

i_round_redThe 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.

i_round_blueThe 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

Setting

Description

Application Pools

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

i_round_blueEnable 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.

Description

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.

i_round_blueThis 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.

i_round_blueIt is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).

i_round_blueFor 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 (i_priority_1) to the highest priority (i_priority_5).

Description

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.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary 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.
    i_round_redYou 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 b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

Schedules, Dependencies, and Maintenance Window

i_round_blueYou 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.

Channel Unit Configuration

i_round_blueWhich 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 List

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

Channel

Description

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

i_round_blueThis 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.
