Monitoring Server Resources Using the JMX Console

The JMX Console enables you to monitor and manage services on the CRX server. The sections that follow summarize the attributes and operations that are exposed through the JMX framework.

For information about how to use the console controls, see Using the JMX Console. For background information about JMX, see the Java Management Extensions (JMX) Technology page on the Oracle website.

For information about creating MBeans to manage your services using the JMX Console, see Integrating Services with the JMX Console.

Third-Party Services

Several third-party server resources install MBeans that expose attributes and operations to the JMX console. The following table lists the third-party resources and provides links to more information.

Domain	Type	MBean Class
JMImplementation	MBeanServerDelegate	javax.management.MBeanServerDelegate
com.sun.management	HotSpotDiagnostic	com.sun.management.HotSpotDiagnosticMXBean
java.lang	ClassLoading Compilation GarbageCollector Memory MemoryManager MemoryPool OperatingSystem Runtime Threading	javax.management package
java.util.logging		java.util.logging.LoggingMXBean
osgi.core	bundleState framework packageState serviceState	org.osgi.jmx.framework package

Using the JMX Console

The JMX Console displays information about several services that are running on the server:

• Attributes: Service properties such as configurations or runtime data. Attributes can be read-only or read-write.
• Operations: Commands that you can invoke on the service.

MBeans that are deployed with an OSGi service expose service attributes and operations to the console. The MBean determines the attributes and operations that are exposed, and whether the attributes are read-only or read-write.

The main page of the JMX console includes a table of services. Each row in the table represents a service that is exposed by an MBean.

1. Open the Web Console and click the JMX tab. (http://localhost:4502/system/console/jmx)
2. Click a cell value for a service to see the attributes and operations for the service.
3. To change an attribute value, click the value, specify the value in the dialog box that appears, and click Save.
4. To invoke a service operation, click the operation name, specify argument values in the dialog box that appears, and click Invoke.

Using External JMX Applications for Monitoring

CRX allows external applications to interact with Managed Beans (MBeans) via Java Management Extensions (JMX). Using generic consoles such as JConsole or domain-specific monitoring applications, allows getting and setting CRX configurations and properties, and the monitoring of performance and resource usage.

Using JConsole to connect to CRX

To connect to CRX using JConsole, follow these steps:

1. Open a terminal window.

2. Enter the following command:

   jconsole

JConsole will start and the JConsole window will appear.

Connecting to a local CRX process

JConsole will display a list of local Java Virtual Machine processes. The list will contain two quickstart processes. Select the quickstart “CHILD” process from the list of local processes (usually the one with the higher PID).

Connecting to a remote CRX process

To connect to a remote CRX process, the JVM that hosts the remote CRX process must be enabled to accept remote JMX connections.

To enable remote JMX connections, the following system property must be set when starting the JVM:

com.sun.management.jmxremote.port=portNum

In the property above, portNum is the port number through which you want to enable JMX RMI connections. Be sure to specify an unused port number. In addition to publishing an RMI connector for local access, setting this property publishes an additional RMI connector in a private read-only registry at the specified port using a well known name, “jmxrmi”.

By default, when you enable the JMX agent for remote monitoring, it uses password authentication based on a password file that needs to be specified using the following system property when starting the Java VM:

com.sun.management.jmxremote.password.file=pwFilePath

See the relevant JMX documentation for detailed instructions on setting up a password file.

Example:

$ java
  -Dcom.sun.management.jmxremote.password.file=pwFilePath
  -Dcom.sun.management.jmxremote.port=8463
  -jar ./cq-quickstart.jar

Using the MBeans provided by CRX

After connecting to the quickstart process, JConsole provides a range of general monitoring tools for the JVM that CRX is running in.

To access CRX’s internal monitoring and configuration options, go to the MBeans tab, and from the hierarchical content tree on the left, select the Attributes or Operations section that you are interested in. For example, the com.adobe.granite/Repository/Operations section.

Within that section, select the desired attribute or operation in the left pane.
