Servers

The Servers option displays a list of available servers. You can select a server that is online to view information, requests, data, channels, events, or tasks.

• Server List
  The Server List displays the online and offline servers in the environment. You can select a server that is online to view its information or ping its host. When you select a server, its host name and port number display in the left pane. If a server is offline, the visual indicator in the status column shows an orange circle with an exclamation mark. You cannot select or ping a server that is offline.
• Information
  The Information option summarizes the basic system environment information for the selected server, such as the number of processors and the operating system. You can also view the amount of total and free physical memory, committed virtual memory, swap space, class paths, and length of time the server has been available.
• Requests
  The Requests option displays all requests made to the server, for example, transaction requests. You can drill down to see statistics for each request, such as the total number of requests, the success and failure count, and the average response time.
• Data
  The Data option displays performance monitoring statistics for the selected server, such as EhCache statistics, connection, caching, and entity access. You can enable or disable performance monitoring.
• Channels
  The Channels option displays the number of messages received, sent, and failed to send. The list shows the last 100 messages that were generated. You can select a message to view the details, such as the date and time stamp. You can also refresh the list to show the most recently sent or received messages.
• Events
  The Events option displays statistics generated by the event system. The event summary displays the total number of events that the event handlers have generated and processed. An event handler is a procedure that is called when a corresponding event occurs. For an event to be processed by a handler, there has to be an event handler registered for the event name and an available thread from the process pool as determined by the event handler. A single event handler instance is associated with a single event name only.
• Tasks
  The Tasks option displays statistics generated by the event system for tasks and task handlers. Tasks are internal date and time actions scheduled for execution at known repeated intervals. Tasks call task handlers. An empty task list indicates there are no scheduled events. A task is not directly related to an event, because tasks are not stored in the event system and do not require a task handler to generate historical events. However, the event system initiates and processes task actions.
