PRTG Manual: Data Hub Rule Sensor

Enabled Beta Sensors experimental feature

This sensor requires that the Beta Sensors experimental feature is enabled.

For more information, see the Knowledge Base: What are beta sensors and how can I use them?

Credentials

This sensor requires credentials for PRTG Data Hub in the settings of the parent device.

Performance impact

This sensor has a very low performance impact.

Limits

This sensor has predefined limits for several metrics.

Rule

The name of the rule that this sensor monitors.

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.

Last Message In

The time since the last incoming message

Messages Accepted

The number of messages accepted by the rule over time

Messages Dropped

The number of messages dropped by the rule

This channel has default limits:

• Upper error limit: 0

Messages In

This channel is the primary channel by default.

The number of incoming messages over time

Messages Out

The number of outgoing messages over time

Messages Rejected

The number of messages rejected by the rule over time

Traffic In

The incoming traffic

Traffic Out

The outgoing traffic
