PRTG Manual: Cluster Health Sensor
The Cluster Health sensor monitors the health of a failover cluster and indicates the system health status of PRTG.
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
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? |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- clusterhealthsensor
For more information about basic sensor settings, see section Sensor Settings.

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:
|
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. |
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.
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 This channel has a default limit:
|
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 This channel is the primary channel by default. |
