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, which is part of the NaturalONE documentation).

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.
