To group servers together so that health rules can be applied to the specific server groups, use the Machine Hierarchy property. This property enables you to group servers into arbitrary hierarchies by specifying a hierarchical path to the server. Servers can be grouped based on departments, geographic locations such as data centers, or other organizational units. You can then create health rules that apply to these departments.
The server hierarchy displays in the Metric Browser, on the Servers list, and on Server Visibility dashboard.
You need a Server Visibility license to use this feature.
You can specify the Machine Hierarchy property using
controller-info.xml, a system property, or an environment variable.
To achieve something like this where you group servers into geo locations, perhaps representing different data centers:
Use the machine-path element in controller-info.xml configuration file to specify the tier and node, for example:
Metric Browser view for this example:
When creating health rules, on the Affected Entities tab you can select one or more subgroups.
