ADEI provides set of interfaces to facilitate access to the configuration and collected data. All interfaces are accessible by means of standard HTTP GET requests. The request parameters are supplied using GET parameters. The response is normally returned using XML or JSON encoding. The ''getdata'' and ''getimage'' requests return the data or image in the specified format.
