The goals of the online monitoring API FAQ is to show how JAS can be used in a client-server based real-time monitoring framework. It documents changes and extensions that have been made in the JAS architecture to support online monitoring applications. These changes were initially motivated by the requirements of the BaBar collaboration, which have used JAS as a part of their online monitoring system, however the methods described here are in no way specific to BaBar.
The online monitoring API can be used to access histograms which have been created in languages other than Java. It is possible to use either Corba or the Java Native Interface (JNI) to access histograms created in other languages.
