Generic MBean client for FMW JVM's (Coherence, WLS etc)

Having done some work with MBeans in OC4J 10.1.3.x I decided with the help of steve to create a query tool which allowed you to view the properties/attributes of any MBean from the command line. The JMX API makes it easy to write a generic tool so in the end I can query any JVM with an MBean Server using the tool. In short this is what I did using spring to ensure it was easy to setup with XML and of course run with ANT. Whats good about this is I can just query the MBeans I want to see rather then all of them. Early days but it does what I need it to do at this stage. Different output methods is what I want to do next, currently it just goes to standard out / console.

Step 1 - Define a connection Interface

package oracle.support.rda.server;

import java.util.Hashtable;

import javax.management.MBeanServerConnection;
import javax.management.remote.JMXServiceURL;

public interface ServerConnection 
{
  public void doConnection(String url) throws Exception;
  public void doConnection(JMXServiceURL jmxServiceURL, Hashtable env) throws Exception;
  public MBeanServerConnection getConnection();
  public boolean isConnected();
  public void close ();
}

Step 2 - Create an abstract class which implements the interface , pretty much does everything you need to connect to a MBean Server.

package oracle.support.rda.server;

import java.util.Hashtable;
import java.util.logging.Level;
import java.util.logging.Logger;

import javax.management.MBeanServerConnection;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;


public abstract class ServerConnectionBase implements ServerConnection
{
  private JMXConnector jmxCon = null;
  private Logger logger = Logger.getLogger(this.getClass().getName());
  
  public ServerConnectionBase()
  {
  }

  public void doConnection(String url) throws Exception
  {
    logger.log(Level.INFO, "JMX Service URL = " + url);
    JMXServiceURL serviceURL = new JMXServiceURL(url);

    jmxCon = JMXConnectorFactory.connect(serviceURL);
  }

  public void doConnection(JMXServiceURL jmxServiceURL, Hashtable env) throws Exception
  {
    logger.log(Level.INFO, "Service URL Path = " + jmxServiceURL.getURLPath());
    jmxCon = JMXConnectorFactory.connect(jmxServiceURL, env);    
  }
  
  public MBeanServerConnection getConnection()
  {
    MBeanServerConnection mbs = null;

    if (jmxCon != null) 
    {
        try 
        {
            mbs = jmxCon.getMBeanServerConnection();
        } 
        catch (Throwable t) 
        {
            logger.log(Level.SEVERE,
                      "** FMW-RDA [ServerConnectionBase.getConnection] : Unable to retrieve MBeanServerConnection");
        }
    }

    return mbs;
  }

  public boolean isConnected()
  {
    boolean ret = false;
    if (jmxCon == null) 
    {
        return false;
    } 
    else 
    {
        try 
        {
            jmxCon.getConnectionId();
            return true;
        } 
        catch (Throwable t) 
        {
            // no need to do anything here
        }
    }

    return ret;
  }

  public void close()
  {
    if (jmxCon != null) 
    {
        try 
        {
            jmxCon.close();
            jmxCon = null;
        } 
        catch (Throwable t) 
        {
        }
    }
  }

}

Step 3 -Finally a class which connects to a WLS 11g instance

package oracle.support.rda.server.connections.wls;

import java.net.URL;

import java.util.Hashtable;
import java.util.Properties;
import java.util.logging.Logger;

import javax.management.remote.JMXConnectorFactory;

import javax.management.remote.JMXServiceURL;

import javax.naming.Context;

import oracle.support.rda.server.ServerConnectionBase;
import oracle.support.rda.server.connections.coherence.CohJMXConnection;

public class WLSJMXConnection extends ServerConnectionBase
{
  private static WLSJMXConnection instance = null;
  private Logger logger = Logger.getLogger(this.getClass().getName());
  private String serviceURL = null;
  
  static
  {
    try
    {
      instance = new WLSJMXConnection();
    }
    catch (Exception e)
    {
      throw new RuntimeException(e.getMessage(), e);
    }
  }
  
  private WLSJMXConnection() throws Exception
  {
    JMXServiceURL jmxServiceURL = null;
    Hashtable h = new Hashtable();
    
    if (instance == null)
    {
      Properties props = new Properties();
      
      URL url = ClassLoader.getSystemResource("server.properties");
      props.load(url.openStream());

      h.put(Context.SECURITY_PRINCIPAL, props.getProperty("wls.username"));
      h.put(Context.SECURITY_CREDENTIALS, props.getProperty("wls.password"));
      h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
         "weblogic.management.remote");
      h.put("jmx.remote.x.request.waiting.timeout", new Long(10000));

      serviceURL = (String) props.getProperty("serviceurl");
      
      jmxServiceURL = 
        new JMXServiceURL(serviceURL);
      
    }
    
    super.doConnection(jmxServiceURL, h);
  }

  public static WLSJMXConnection getInstance() throws Exception
  { 
    return instance;
  }

  public String getServiceURL()
  {
    return serviceURL;
  }
}

So we would then use this connection in a spring XML file as follows using a Factory Class which defines the connections we wish to use. At the time of this post I had an OC4J 10.1.3.x, WLS 10.3.x and Coherence connection implementation classes which extend ServerConnectionBase.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

  <bean id="serverConnection" 
        class="oracle.support.rda.server.ConnectionFactory" 
        factory-method="getWLSConnection" 
        singleton="true">
  </bean> 

Step 4 - Define an interface which allows us to invoke queries against the MBeans and view there attributes

package oracle.support.rda.spring.queries;

import javax.management.MBeanServerConnection;

import oracle.support.rda.spring.exception.RDAQueryException;

public interface RDAQuery 
{
    public Object invoke(MBeanServerConnection mbs) throws RDAQueryException;
    public void setMBeanName(String mbeanName);
}

Step 5 - Define a implementation class for the query interface. The abstract class has been left out here but that's what does all the work of viewing the MBean attributes etc..

package oracle.support.rda.spring.queries;

import java.util.logging.Logger;

import javax.management.MBeanServerConnection;

import oracle.support.rda.spring.exception.RDAQueryException;

public class GenericQuery extends RDAQueryBase
{
  Logger logger = Logger.getLogger(this.getClass().getName());
  
  @Override
  public Object invoke(MBeanServerConnection mbs) throws RDAQueryException 
  {
      logger.info("Generic Query called");
      return super.invoke(mbs);
  }
}

Step 6 - Define the MBeans I wish to query as shown in the example below.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

  <bean id="serverConnection" 
        class="oracle.support.rda.server.ConnectionFactory" 
        factory-method="getWLSConnection" 
        singleton="true">
  </bean>
  
  <bean id="machineQuery" class="oracle.support.rda.spring.queries.GenericQuery">
    <property name="MBeanName">
      <value>com.bea:Name=machine1,Type=Machine</value>
    </property>
  </bean>

  <bean id="nodeMgrQuery" class="oracle.support.rda.spring.queries.GenericQuery">
    <property name="MBeanName">
      <value>com.bea:Name=machine1,Type=NodeManager,Machine=machine1</value>
    </property>
  </bean>
  
  <bean id="appleJVMQuery" class="oracle.support.rda.spring.queries.GenericQuery">
    <property name="MBeanName">
      <value>
        com.bea:ServerRuntime=apple,Name=apple,Type=JVMRuntime      
      </value>
    </property>
    <!--
    The following properties will not be displayed, giving you
    control over what information you show.
    -->
    <property name="nukedAttributes">
      <list>
        <value>ThreadStackDump</value>  
      </list>
    </property>
  </bean>
  
  <bean id="jdbcResourceQuery" class="oracle.support.rda.spring.queries.GenericQuery">
    <property name="MBeanName">
      <value>
        com.bea:Name=jdbc/scottDS,Type=JDBCSystemResource    
      </value>
    </property>
  </bean>

  <bean id="jdbcPropertiesQuery" class="oracle.support.rda.spring.queries.GenericQuery">
    <property name="MBeanName">
      <value>
        com.bea:Name=user,Type=weblogic.j2ee.descriptor.wl.JDBCPropertyBean,Parent=[pastest_dom]/JDBCSystemResources[jdbc/scottDS],Path=JDBCResource[jdbc/scottDS]/JDBCDriverParams/Properties/Properties[user]  
      </value>
    </property>
  </bean>

  <!--  
    This defines the Invoker object, which gets passed 
    a reference to the ServerConnection AND the list of queries
   -->
  <bean id="queryInvoker" class="oracle.support.rda.spring.invoker.QueryInvoker">
    <property name="serverConnection" ref="serverConnection"/>
    <property name="rdaQueries">
      <list>
        <ref bean="machineQuery"/>
        <ref bean="nodeMgrQuery"/>
        <ref bean="appleJVMQuery"/>
        <ref bean="jdbcResourceQuery"/>
        <ref bean="jdbcPropertiesQuery"/>
      </list>
    </property>
  </bean>    

  <!--  
   Bean used to list of MBeans available for use
   -->
  <bean id="showMBeans" class="oracle.support.rda.spring.invoker.MBeanViewer">
    <property name="serverConnection" ref="serverConnection"/>
  </bean> 
  
</beans> 

I provided the ability to remove properties you really don't wish to view for the MBean itself. The name nukedAttributes came from steve.

The queryInvoker bean is what actually invokes the queries themselves which takes a List of query beans themselves and uses the MBean Server Connection we defined at the start. That class is as follows

package oracle.support.rda.spring.invoker;
package oracle.support.rda.spring.invoker;

import java.util.ArrayList;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;

import oracle.support.rda.server.ServerConnection;
import oracle.support.rda.spring.exception.RDAQueryException;
import oracle.support.rda.spring.queries.RDAQuery;

@SuppressWarnings("unchecked")
public class QueryInvoker {

    private final Logger logger = Logger.getLogger(this.getClass().getName());
    private ServerConnection serverConnection;
    private List<RDAQuery> rdaQueries = new ArrayList<RDAQuery>();
    
    /**
     * @param rdaQueries the rdaQueries to set
     */
    public void setRdaQueries(List rdaQueries) 
    {
      System.out.println(rdaQueries.toString());
      this.rdaQueries = rdaQueries;
    }

    /**
     * @param mbeanServerConnection the mbeanServerConnection to set
     */
    public void setServerConnection(ServerConnection serverConnection) 
    {
      this.serverConnection = serverConnection;
    }

    public QueryInvoker() 
    {
      // TODO Auto-generated constructor stub
      logger.setLevel(Level.ALL);
    }
    
    public int getQueryCount() 
    {
      return rdaQueries.size();
    }
    
    public void run() 
    {
      for(RDAQuery query: rdaQueries) 
      {
          
        try 
        {
            System.out.println(query.invoke(serverConnection.getConnection()));    
        } 
        catch (RDAQueryException e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
      }
    }
       
}

Output of this running is as follows against OC4J 10.1.3.x in an OPMN managed environment.

If you wanted to create queries against a Coherence Server your query-beans.xml file would look like this. The idea here is to specifically query only the MBeans your interested in so you could easily tailor it to meet your needs such as monitoring a JDBC connection pool. The bean with id "showMBean" is used to view all available MBeans you can use.
