• The Monitor controls communication between the Worker Agent and the worker machine. It allows the server to communicate with the worker machine, regardless whether the worker is actually running. This allows the server to view log files from each of the applications (monitor, helper, and worker) even when the worker fails to start. The Monitor also receives the start command from the server when the worker needs to start.

• If multiple instances of a worker are required, there is only one “workermonitor” process, which starts a new instance of the worker for each instance.

• The monitor starts, then WVS requests that the monitor start the worker. The monitor then starts the helper, which in turn starts the worker.
