This section lists and describes key terms that you
               should be familiar with when using the Single Pane of Glass (SPOG)
               and Sentinel.
            
            
               - Sentinel. A standalone server that provides management
                  and monitoring services across multiple iSM instances throughout
                  the enterprise.
               
 
               - Single Pane of Glass (SPOG). A web application interface
                  to Sentinel that provides users with the ability to manage and monitor
                  iWay Service Manager (iSM) in an enterprise environment.
               
 
               - Configuration. An arrangement of descriptive ISM metadata
                  is used to instantiate iSM. In Sentinel, configurations are packaged
                  as .ita files, which are also known as templates.
               
 
               - Server. A single instance of iSM running the master configuration
                  (for example, base).
               
 
               - Application. A deployed iSM runtime configuration, also
                  known as an iWay Integration Application (iIA).
               
 
               - Envoy. An iSM extension running on a Server, which provides
                  monitoring and management services to Sentinel.
               
 
               - Package. A .zip file containing a set of resources including
                  iSM descriptive metadata and/or file artifacts.
               
 
               - User. A person who interacts with SPOG.
               
 
               - Server Task. A Sentinel task that offers services (subprograms).
                  This is typically a batch task or asynchronous task.
               
 
               - Health Model. An algorithm designed to detect server
                  issues that could eventually result in service disruptions.
               
 
               - Ghosts. Objects that once existed, have disappeared,
                  but still exist in the Sentinel graph.
               
 
               - Zombies. An iSM server or application that cannot respond
                  to requests for status and for which Sentinel does not have a corresponding
                  history to classify as severe health.
