▼To Use the PetStore Example

The following example illustrates how the asadmin tool might be used for monitoring purposes.

A user wants to inspect the number of calls made to a method in the sample PetStore application after it has been deployed onto the Enterprise Server. The instance onto which it has been deployed is named server. A combination of the list and get commands are used to access desired statistics on a method.

1Start the Enterprise Server and the asadmin tool.

2Set some useful environment variables to avoid entering them for every command:

asadmin> export AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=admin123 asadmin>export AS_ADMIN_HOST=localhost AS_ADMIN_PORT=4848

3List monitorable components for instance server: asadmin> list --user adminuser --monitor server*

Returns (output will be similar to):

server server.applications server.applications.CometEJB server.applications.ConverterApp server.applications.petstore
