Although they can be used as a standalone entity, worker nodes are typically presented through a process client which shows the workers placed in a hierarchy of groups. The workers and groups are presented to the user as tasks and folders.
The underlying Folder can be used to build a simple process client. For most user-facing applications, the standard Process Client product (installed using metrici.products.process_client.install) is more appropriate. The Metrici Portal process automation installation, usage and administration guide provides an overview of the Process Client.
