Supported Versions: Applications Manager supports monitoring of Oracle Application Servers 10g.
Prerequisites: Applications Manager uses the Dynamic Monitoring Service (DMS) provided by Oracle Application Server to monitor the same. For this reason, the DMS Servlet has to be made accessible to the system where the Applications Manager is running. Refer Prerequisites section.
To create a Oracle Application server monitor, follow the steps given below:
Oracle Application servers are monitored based on the attributes listed below. The monitoring details of Oracle Application server are represented graphically that helps to understand the parameters with ease. You can also configure thresholds to the attributes monitored by the server based on these details.
