Edit the file /var/AppServer-base/domains/domain1/config/domain.xml and change all module-monitoring-level settings from OFF to HIGH. Alternatively:
Restart Application Server with the following commands:
cd AppServer-base/appserv/bin asadmin stop-domain domain1 asadmin start-domain user myUser domain1
Enter the password for myUser when prompted.
If you have deployed and monitored an instance of Portal Server with Application Server, the process of restarting Application Server interferes with Portal Server monitoring. To make the Portal Server instance appear in the Monitoring Console, you must visit a portal page in a browser. For example, load the page http://portalserv.example.com:8080/portal to allow monitoring of portalserv.example.com.
Due to a limitation, the monitored objects for Application Server are removed from the Monitoring Framework when Application Server crashes or is down. When this happens, Application Server disappears from the Monitoring Console and can no longer be monitored.
