VMware Host Performance (REST & VI/JSON) Sensor

Credentials

The sensor requires credentials for VMware vSphere in the settings of the parent device.

Parent device

This sensor requires a parent device as of vCenter Server 8.0 Update 1.

If you set up this sensor on multiple probes (for example, when using remote probes or when running a failover cluster), you might need to change the settings of your VMware host so that it accepts more incoming connections. Otherwise, you might receive connection timeouts and errors when running many VMware sensors with a short scanning interval.

For more information, see the Knowledge Base: How can I increase the connection limit on VMware systems?

Meta-scan

This sensor uses the meta-scan feature. After sensor creation, some settings might appear for reference purposes only.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a very low performance impact.

Limits

This sensor has predefined limits for one or several metrics.

Display Name

Shows the display name of the ESXi host that this sensor monitors.

Host ID

Shows the ID of the ESXi host that this sensor monitors, as used by the vSphere API.

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:

• 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 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.

Result Handling

Define what PRTG does with the sensor result:

• Discard result (default): Do not store the sensor result.
• Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

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

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

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.
