Consider the following remarks and requirements for this sensor:



Performance impact

  • This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.

Enabled CIM Interface on ESXi Host

  • This sensor requires that the CIM interface is enabled on the ESXi host. As of ESXi 6.5, you must manually enable CIM.

i_square_cyanFor more information, see the Knowledge Base: How do I enable the CIM interface on VMware ESXi 6.5?

Windows Server

  • We recommend Windows Server 2016 on the probe system for best performance of this sensor.


  • This sensor requires credentials for Linux/Solaris/macOS (SSH/WBEM) systems in the settings of the parent device.

Parent device

  • This sensor requires that the parent device is a VMware ESXi server as of version 5.2.


  • This sensor only supports IPv4.


  • This sensor uses lookups to determine the status values of one or more channels.

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

Hardware Element

The hardware element that this sensor monitors.

Automatic Sensor Status

Define if the sensor changes its status depending on the health status reading:

  • Set sensor to warning or down status (default): Set the sensor to the Warning or the Down status when the server returns respective values. The sensor also changes to the Down status if the connection to the server fails.
  • Report the current reading: Never change the sensor's status dependent on the values returned by the server. The sensor only changes to the Down status if the connection to the server fails.

Result Handling

Define what PRTG does with the sensor result:

  • Discard result (default): 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.

i_podThis option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

i_round_blueIn a cluster, PRTG stores the result in the PRTG data directory of the master node.

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.

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 this sensor shows different channels:

  • 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. 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.

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.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

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




The current


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


The health status

  • Up status: OK Unknown
  • Warning status: Degraded, Minor
  • Down status: Critical, Major, Non Recoverable Error
