Adaptive Server Enterprise Monitor consists of four components that gather or display Adaptive Server performance data:
Monitor Server – a server that collects Adaptive Server performance data in real time and makes the data available to the other Adaptive Server Enterprise Monitor components. Monitor Server is a Sybase Open Server™ application.
Historical Server – a server that obtains Adaptive Server performance data from Monitor Server and saves the data in files for deferred analysis. Historical Server is a Sybase Open Server application.
Monitors in the Adaptive Server plug-in for Sybase Central (Monitor Viewer) – the monitors provide a graphical user interface to Monitor Server. They obtain Adaptive Server performance data from Monitor Server and display the data in real time in tables and graphs.
Monitor Client Library – an application programming interface to Monitor Server available to users for developing monitoring applications. Monitor Viewer and Historical Server are Monitor Client Library applications.
