Remarks

  • This sensor requires at least Windows Server 2008 R2 on the probe system.
  • This sensor requires Microsoft Internet Information Services (IIS) as of version 7.5 on the target system.
  • This sensor requires that the Remote Registry Windows service runs on the target system.
  • This sensor requires credentials for Windows systems in the settings of the parent device.
  • This sensor supports IPv6.
  • This sensor has a low performance impact.
  • This sensor uses lookups to determine the status values of one or more channels.

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

Windows version

To work with Windows performance counters, this sensor requires that at least Windows Server 2008 R2 is installed on the probe system (on every cluster node, if on a cluster probe).

IIS version 7.5

To monitor IIS application pools, this sensor needs at least IIS version 7.5 to be installed on the target system.

Remote Registry Windows service

To work with Windows performance counters,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.

Windows credentials

This sensor requires credentials for Windows systems in the settings of the parent device. We recommend that you 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 system. 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.

Setting

Description

Sensor Name

Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.

i_round_blueIf the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?

Parent Tags

The 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 select Stack channels on top of each other above.

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.

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 application pool status

  • 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
