DPA server to client communications

The client machine does not listen on any port for requests coming from the server. All transfer is initiated with a request from the client machine. In response to the client requests, the server sends information on configuration and triggers (if configured).

Configuration

In response to a call from the client, the server sends approximately 200 Bytes of configuration data to the client at each transfer interval. The connection is made through a web service request.

Trigger information

When the client starts, at system start up or user log on, each client machine receives trigger information from the server. This data is sent in response to a request from the client. The connection is made through a web service request. This information is stored in memory until the next time the Desktop and Process Analytics client starts. The size of the trigger information depends on the number and nature of the defined triggers. The trigger information contains between 300 Bytes and 500 Bytes for each trigger defined. Trigger information is only sent on start up or on trigger redefinition. When any trigger is redefined, all trigger data is sent to the client.
