When you display the Process window for the Master Ping process, you see that the process consists of four unique activities. To examine the activities of the process in more detail, we have numbered each node for easy referencing below. The numbers themselves are not part of the process diagram.

The Workflow Agent Ping/Acknowledge workflow begins when you launch the Master Ping Process using the Launch Processes web page. You can optionally provide a to agent, event name, out agent, event key, and event message. See: Testing Workflow Definitions.

The workflow begins at node 1 with the Start activity. At node 2, the master process spawns a detail process for each inbound agent that you have defined on the local system or on external systems. The detail process pings the agent by sending it a Ping Agent event and waits to receive an acknowledgement in the form of an Acknowledge Ping event.

Node 3 is a Wait for Flow activity that waits for all the detail processes to complete. When all the detail processes have completed, the master process ends.
