## 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 Application 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.

1. Start the Application Server and the `asadmin` tool.

2. Set 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=4849

3. List 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
       server.http-service
       server.resources
       server.thread-pools

   The list of monitorable components includes `thread-pools`, `http-service`, `resources`, and all deployed (and enabled) `applications`.

4. List the monitorable subcomponents in the `PetStore` application (`-m` can be used instead of `--monitor`):

   `asadmin> list -m server.applications.petstore`

   Returns:

       server.applications.petstore.signon-ejb_jar
       server.applications.petstore.catalog-ejb_jar
       server.applications.petstore.uidgen-ejb_jar
       server.applications.petstore.customer-ejb_jar
       server.applications.petstore.petstore-ejb_jar
       server.applications.petstore.petstore\.war
       server.applications.petstore.AsyncSenderJAR_jar
       server.applications.petstore.cart-ejb_jar

5. List the monitorable subcomponents in the EJB module `signon-ejb_jar` of the `PetStore` application:

       asadmin> list -m server.applications.petstore.signon-ejb_jar

   Returns:

       server.applications.petstore.signon-ejb_jar.SignOnEJB
       server.applications.petstore.signon-ejb_jar.UserEJB

6. List the monitorable subcomponents in the entity bean `UserEJB` for the EJB module `signon-ejb_jar` of the `PetStore` application:

       asadmin> list -m server.applications.petstore.signon-ejb_jar.UserEJB

   Returns (with dotted name removed for space considerations):

       server.applications.petstore.signon-ejb_jar.UserEJB.bean-cache
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-pool

7. List the monitorable subcomponents in the method `getUserName` for the entity bean `UserEJB` in the EJB module `signon-ejb_jar` of the `PetStore` application:

       asadmin> list -m
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.getUserName

   Returns:

       Nothing to list at server.applications.petstore.signon-ejb_jar.
       UserEJB.bean-methods.getUserName. To get the valid names beginning with a
       string, use the wildcard "*" character. For example, to list all names
       that begin with "server", use "list server*".

8. There are no monitorable subcomponents for methods. Get all monitorable statistics for the method `getUserName`.

       asadmin> get -m
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.getUserName.*

   Returns:

       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-count = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-description = Provides the time in milliseconds
          spent during the last successful/unsuccessful attempt to execute the
          operation.
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-lastsampletime = 1079981809259
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-name = ExecutionTime
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-starttime = 1079980593137
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-unit = count
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-count = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-description = Provides the number of times an
          operation was called, the total time that was spent during the
          invocation and so on.
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-lastsampletime = 1079980593137
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-maxtime = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-mintime = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-name = ExecutionTime
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-starttime = 1079980593137
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-totaltime = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.methodstatistic-unit =
        server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumerrors-count = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumerrors-description = Provides the total number of errors
          that occured during invocation or execution of an operation.
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumerrors-lastsampletime = 1079981809273
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumerrors-name = TotalNumErrors
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumerrors-starttime = 1079980593137
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumerrors-unit = count
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumsuccess-count = 0
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumsuccess-description = Provides the total number of
          successful invocations of the method.
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumsuccess-lastsampletime = 1079981809255

       getUserName.totalnumsuccess-starttime = 1079980593137
       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.totalnumsuccess-unit = count

9. To also get a specific statistic, such as execution time, use a command such as the following:

       asadmin> get -m server.applications.petstore.signon-ejb_jar.
       UserEJB.bean-methods.getUserName.executiontime-count

   Returns:

       server.applications.petstore.signon-ejb_jar.UserEJB.bean-methods.
       getUserName.executiontime-count = 1
