Remarks

Consider the following remarks and requirements for this sensor:

Remark

Description

Performance impact

This sensor has a very low performance impact.

Sensor creation

PRTG automatically creates this sensor with a cluster installation. You cannot manually delete it or add it.

Down status

If at least one cluster node is disconnected, this sensor shows the Down status by default.

Cluster node states

You can review the states of each cluster node on this sensor's Overview tab.

Cluster node data

You can choose the cluster node for which you want to show data (or for all cluster nodes) on the monitoring data review tabs. For more information, see the Knowledge Base: What options do I have to review my monitoring data in detail?

Basic Sensor Settings

Basic Sensor Settings

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

Setting

Description

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.

Channel

Description

Cluster Messages In

The number of ingoing cluster messages per minute

Cluster Messages Out

The number of outgoing cluster messages per minute

Cluster Nodes Disconnected

The number of disconnected cluster nodes

i_round_blueThis channel has a default limit:

  • Upper error limit: 0

Connects

The number of connects per minute

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

Outbound Cluster Connections

The number of outbound cluster connections

i_round_blueThis channel is the primary channel by default.
