Thefollowing example illustrates how the asadmin tool might be used for monitoring purposes.
Auser wants to inspect the number of calls made to a method in the sample PetStore
applicationafter it has been deployed onto the Enterprise Server. The instance onto which it has
beendeployed is named server. A combination of the list and get commands are used to
accessdesired statistics on a method.
Startthe Enterprise Server and the asadmin tool.
Setsome useful environment variables to avoid entering them forevery command:
asadmin> export AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=admin123
asadmin>export AS_ADMIN_HOST=localhost AS_ADMIN_PORT=4848
Listmonitorable components for instance server:
asadmin> list --user adminuser --monitor server*
