Work with the App Group Map
There are two types of App Groups: Destination App Groups (formerly Providing) and Source App Groups (formerly Consuming). Destination App Groups provide service to an application instance and Source App Groups rely on those services to run the application instances.
You can search for specific App Groups and see the associated workloads, traffic and segmentation rule coverage between the workloads in that App Group, other App Groups that provide (Destination) or consume (Source) its services, and segmentation rule coverage for the traffic between App Groups.
How App Groups are Created and Associated
An App Group is created when:
A new workload is added or discovered and there are no existing App Groups using the workload's labels
A label is changed on an existing workload and there are no existing App Groups using that label combination
A workload is associated with an App Group when:
A workload is paired or unpaired with the PCE
A label is changed on a workload
When a new workload is added, it is associated with any existing App Group that uses the workload's labels. When no App Group with those labels exists, an App Group is created and associated with the workload.
When the App Group uses a different Location label but has the same Application and Environment labels as an existing App Group, a new App Group using the Application, Environment, and Location labels is created and associated with the workload.
Configure Number of Matching App Group Labels
App Groups are created automatically based on workload labels and the App Group Type setting. You can configure App Groups to require two or three matching labels.
Application and Environment labels only (the Location label is ignored). This is the default.
Application, Environment, and Location labels
Note
If the Application | Environment option is selected, the workloads displayed in the Illumination map and the App Group map are not the same and there is no link to return to the Illumination map.
To specify whether App Groups should be created with two or three labels as described above:
In the left navigation, in the Explore section, click App Groups.
Click Edit App Group Type.
Select either Application | Environment (default) or Application | Environment | Location.
Click Save.
Caveats
When the App Group Configuration setting is changed, the list of “Most Recently Viewed App Groups” is cleared.
If you have a large number of workloads in your organization, it may take up to five minutes to regenerate the Map.
