PRTG Manual: Cluster Health Sensor
The Cluster Health sensor monitors the health of a failover cluster and indicates the system health status of PRTG.
Cluster Health Sensor
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.
▪Dutch: Cluster Status
▪French: État du cluster
▪German: Cluster-Zustand
▪Japanese: クラスターの正常性
▪Portuguese: Funcionamento do cluster
▪Russian: Работоспособность кластера
▪Simplified Chinese: 群集健康状况
▪Spanish: Salud de clúster
▪PRTG automatically creates this sensor with a cluster installation. You cannot manually delete it or add it.
▪If at least one cluster node is disconnected, this sensor shows the Down status by default.
▪You can review the states of each cluster node on the sensor's Overview tab.
▪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?
▪This sensor has a very low performance impact.

Basic Sensor Settings
Setting |
Description |
|---|---|
Sensor Name |
Enter a name to identify the sensor. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.
|
Parent Tags |
Shows tags that the sensor inherits from its parent device, parent group, and parent probe.
|
Tags |
Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor: ▪clusterhealthsensor |
Priority |
Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority ( |
Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.
Sensor Display
Setting |
Description |
|---|---|
Primary Channel |
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed below the sensor's name. The available options depend on what channels are available for this sensor.
|
Graph Type |
Define how different channels are shown for this sensor: ▪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. |
Stack Unit |
This setting is only visible if you enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are stacked 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. |
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 
under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
Scanning Interval
For more information, see section Root Group Settings, section Scanning Interval.
Access Rights
For more information, see section Root Group Settings, section Access Rights.
Which 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 |
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
