Example of Application Instrumented with Monitoring

The Bank Application example simulates the work of a bank: several clients are making transactions at bank counters at a certain time with a random amount of money.

The following classes are used:

• Client.java - represents a client of the bank who performs a transaction.
• Counter.java - represents a counter desk open for transactions with clients.
• ClientThread.java - a thread that instantiates com.sap.monitor.bank.Client and executes the gotoCounter(Client client) method on an object of type Transaction .
• Transaction.java - abstraction for a transaction
• BankServlet.java
  • looks up the MBean Server
  • creates the ObjectName for the BankMBean
  • registers the MBean in the MBean Server
  • recieves "number of threads" and "maximum money amount allowed for one client trasaction" parameters from the index.html file
  • starts/stops the client threads
• PropertiesConsts.java- provides some useful constants
• BankProperties.java
  • loads the bank.properties property file
  • prepares the information for all simple monitors reading from the property file
  • provides methods for sending monitored data
• PropertiesReaderServlet.java - provides a GUI for changing the properties
• BankMBean.java - the management interface of the resource MBean
• Bank - implementation of the resource MBean
  Note

  The Bank Application example source code can be found in the examplesfolder of the SAP NetWeaver Developer Studio installation directory.
