Monitoring

This document covers the following topics:


About the Monitoring Tool

The monitoring tool is used to monitor the sessions that are currently running in the local web container environment.

To monitor the sessions of an application that has been deployed to another web container, you use the monitoring tool directly in the deployed application. A link to that monitoring tool is available on the default index page that is packaged along with the application (see also Content of a Natural for Ajax Web Application).

Sessions which are no longer required can be deleted and memory can thus be freed. For more information on sessions, see Details on Session Management in Special Development Topics, which is part of the Application Designer documentation.

Invoking the Monitoring Tool

When you invoke the monitoring tool, the following editor appears.

Using the Refresh button at the very top of the editor, you can reload the information in the editor and thus show the most recent information.

Active Sessions

The middle of the editor provides a list with all sessions which are currently active.

The monitoring process itself is also considered as a session. When no other sessions are active, the monitoring process is the only session that is listed in the editor.

The following command buttons are available:

System Management

The bottom of the editor provides the following information:

Option Description
Class Loader When you choose the Use latest Version of Applications for new Sessions command button, a new class loader instance is generated. The most recent versions of your applications are then loaded. For example, when an adapter class has been modified, the modified class is loaded and any changes are immediately in effect.

See also Class Loader Concepts in Appendices, which is part of the Application Designer documentation.

When you choose the Open Today's Log File command button, a dialog appears showing the content of the log file.
