Work with the App Group Map
There are two types of App Groups: Providing App Groups and Consuming App Groups. Providing App Groups provide service to an application instance and Consuming 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 or consume its services, and segmentation rule coverage for the traffic between App Groups.
App Group Creation and Association
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 an App Group with those labels does not exist, it 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 App Groups
App Groups are created automatically based on workload labels and the App Group Type setting. App Groups can be configured to require two or three matching labels.
There are two ways to configure App Groups:
App Groups formed by the Application and Environment labels
App Groups formed by the 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 be the same and there is no link to return to the Illumination map.
To specify whether App Groups should be created based on the Application and Environment labels or the Application, Environment, and Location labels:
In the PCE web console menu, choose Settings > App Group Configuration.
The App Group list page appears. The page displays the type of group (two labels or three labels) and the number of workloads per App Group.
Click Set App Group Type.
Select the appropriate radio button (either Application and Environment or Application, Environment, and Location). The default option is Application and Environment.
Click Save
Caveats
When the App Group Configuration setting is changed, the list of “Most Recently Viewed App Groups” is cleared.
When you have a large number of workloads in your organization, it can take up to five minutes to regenerate the Illumination map. To confirm the request has not timed out or is still pending, check the Network tab.
