Monitoring the Server Performance

You can monitor the server performance in two ways: using Logi JReport Server Monitor or using an external method: JMX MBean API or web service API.

Below is a list of the sections covered in this topic:

• Monitoring the Server Performance on Logi JReport Server Monitor
• Monitoring the Server Pperformance Using JMX MBean API or Web Service API

Monitoring the Server Performance on Logi JReport Server Monitor

Logi JReport Server Monitor can show performance counters in graph (Line chart and Bar chart) and text mode.

To monitor the performance of Logi JReport Server on Logi JReport Server Monitor:

1. In the left panel of the Logi JReport Server Monitor home page, select to select any server node.
2. Select the Performance tab and the performance chart of the specified server will be displayed.
3. If you want to configure the performance chart, select the Graph Options button on the toolbar. In the Graph Options dialog, set how many tick marks you need to display on the X axis in the Keep Last N Records text box. In the Y Axis Limit and Y2 Axis Limit text boxes, set respectively the maximum value on the left Y axis and the right Y axis. In the Interval text box, set the time interval (in seconds) the performance chart will use to get data and refresh itself.

   Select the Clear Display button if you want to clear the current display of the performance counters in the performance chart.

   To stop the current display of the performance counters, select the Stop button on the toolbar.

The following are the available counters:

Monitoring the Server Pperformance Using JMX MBean API or Web Service API

To monitor server performance via JMX MBean API:

1. Make your application environment consistent with the JMX specification.
2. In server.properties, set the properties server.rmiserver.enable and server.profiling.enable to true.
3. Run your code. Here is an example:

   ObjectName profilingName = new ObjectName("jinfonet:name=profileCounter");
   ProfilingFactory ft = new ProfilingFactory("127.0.0.1",1129, "d:\\monitor");
   ProfilingCounter profilingCounter = new ProfilingCounter(ft);
   MBeanServer server = MBeanServerFactory.createMBeanServer();
   server.registerMBean(profilingCounter, profilingName);
   ProfileNotifyListener notifyListener = new ProfileNotifyListener();
   profilingCounter.addNotificationListener(notifyListener, null,null);
   // Create an RMI connector and start it 
   JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:9999/server");
   JMXConnectorServer cs = JMXConnectorServerFactory.newJMXConnectorServer(url, null, server);
   cs.start();

   In code part ProfilingFactory ft = new ProfilingFactory("127.0.0.1",1129, "d:\\monitor"), the parameters serverHost and serverRMIPort are used to get server's ProfilingService remote object, parameter homepath is the path of the rmi.auth file which is used for RMI authority checking public ProfilingFactory(String serverHost, int serverRMIPort, String homepath).

4. Check the monitoring result.

To monitor server performance via web service API:

1. Build Logi JReport.war with the makewar buildWar4WS command using the makewar.bat utility in the <install_root>\bin directory.
2. Deploy Logi JReport.war to your application server such as Tomcat or WebSphere.
3. In server.properties, set the properties server.rmiserver.enable and server.profiling.enable to true.
4. Run your code. Here is an example:

   XFire xfire = XFireFactory.newInstance().getXFire();
   XFireProxyFactory factory = new XFireProxyFactory(xfire);
   Class className = jet.server.profiling.ws.service.JReportServerProfilingWs.class;
   String serviceName = "ProfilingService";
   String serviceURL = "http://localhost:8080/jreport/services/ProfilingService";
   Service serviceModel = new ObjectServiceFactory().create(className, serviceName, null, null);
   JReportServerProfilingWs o = (JReportServerProfilingWs)factory.create(serviceModel, serviceURL);
   //Setup properties
   Client client = Client.getInstance(o);
   client.setProperty("mtom-enabled", "true");
   client.setProperty(HttpTransport.CHUNKING_ENABLED, "true");
   //try call getCounter first before check login
   try{
       System.getCounter("totalcompletedtasks"));
        
   }catch(Exception e) {
       e.printStackTrace();
   }
   //call check login then call getCounter and getCounterType
   o.checkLogin("admin", "admin");
   System.getCounter("totalcompletedtasks"));

5. Check the monitoring result. When you run your code, you can call the two methods getCounter() and getCounterType() to get the information you want.

The available counters used in JMX MBean API and web service API are:

In JMX MBean API and web service API, the data type of the profiling counters has to be Decimal. Below is a figure of built-in data type hierarchy that you could refer for the return value:
