PRTG Manual: Multi-Platform Probe Health Sensor

Sensor creation

• PRTG automatically creates this sensor. You cannot delete it. If you manually create the sensor, you can delete it.

Windows

• This sensor does not support Windows operating systems.

Probe device

• You can create this sensor only on a probe device.

IPv6

• This sensor supports IPv6.

Performance impact

• This sensor has a very low performance impact.

Limits

• This sensor has predefined limits for several metrics.

Scanning interval

• The recommended scanning interval of this sensor is 1 minute.

Multi-platform probe

• You can add this sensor to a multi-platform probe.

Knowledge Base

• Knowledge Base: What is the multi-platform probe and how can I use it?

Port

Enter the port number (between 1 and 65535) that this sensor uses to connect to the multi-platform probe. The default port is 23562.

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 last sensor result 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.

CPU Load

The CPU load (%) of the multi-platform probe. Extensive CPU load can lead to false, incomplete, and incorrect monitoring results. This value should usually stay below 50%.

This channel is the primary channel by default.

This channel has default limits:

• Upper error limit: 90%

• Upper warning limit: 80%

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
