<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: WMI Vital System Data v2 Sensor
The WMI Vital System Data v2 sensor monitors vital system parameters via Windows Management Instrumentation (WMI).
The sensor can monitor CPU, thread, memory, network, or pagefile, for example.

Remarks
This sensor has a high performance impact. Try to stay below 200 WMI sensors in total per probe. Above this number, consider using multiple remote probes for load balancing.
This sensor requires WoW64 (Windows 32-bit on Windows 64-bit) for target systems that run Windows Server 2016.
This sensor supports the IPv6 protocol.
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.
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.

Description
Performance Counter
Select the performance counters that you want to monitor. PRTG creates one sensor for each counter that you select.
You see a list of available vital system data values the sensor can monitor on the target device. The available options depend on your configuration. PRTG shows all possible performance counters with the name and instance description (if available).
Choose from the following counters:
CPU
Thread
Memory
Network
Pagefile
You can also select all items or cancel the selection by using the check box in the table header.
Basic Sensor Settings
Click the Settings tab of a sensor to change its settings.
If 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?
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:

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 ().
Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.

Display Name
Shows the display name that the sensor uses to query data from the target device.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Instance
Shows the instance that the sensor uses to query data from the target device.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
WMI Class
Shows the WMI class that the sensor uses to query data from the target device.

Counter
Shows the counter that the sensor uses to query data from the target device.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Time Stamp
Shows the time stamp that the sensor uses to query data from the target device.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Time Frequency
Shows the time frequency that the sensor uses to query data from the target device.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Counter Type
Shows the counter type that the sensor uses to query data from the target device.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.
Result Handling
Define what PRTG does with the sensor result:
Discard result: Do not store the sensor result.
Store result: Store the last sensor result in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file names are Result of Sensor [ID].txt and Result of Sensor [ID].Data.txt. This setting is for debugging purposes. PRTG overwrites these files with each scanning interval.
In a cluster, PRTG stores the result in the PRTG data directory of the master node.

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.
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 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.

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.
Channel
Description
Bytes In All Heaps
The common language runtime (CLR) memory bytes in all heaps
Bytes Total/Sec
The total number of bytes per second
Committed
The committed bytes
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
