Select the application you want to monitor, then click Connect. For information on user names and passwords, see Using Password and Access Files.

To monitor the JVM running jconsole, simply click Connect, using host localhost and the port zero 0. Note : If the JMX agent is using in a connector which is not included in the Java platform, you need to add the connector classes to the classpath when running jconsole as follow:.

The Summary tab displays some key monitoring information on thread usage, memory consumption, and class loading, plus information on the JVM and operating system. The chart shows the JVM's memory use versus time, for heap and non-heap memory, and for specific memory pools. The memory pools available depend on the JVM being used. The bar chart at the lower right shows memory consumed by the memory pools in heap and non-heap memory.

The bar will turn red when the memory used exceeds the memory usage threshold. You can set the memory usage threshold through an attribute of the MemoryMXBean. Heap memory is the runtime data area from which the JVM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects. Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the JVM.

It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors.

The method area is logically part of the heap but, depending on implementation, a JVM may not garbage collect or compact it. Like the heap, the method area may be of fixed or variable size.

The memory for the method area does not need to be contiguous. In addition to the method area, a JVM implementation may require memory for internal processing or optimization which also belongs to non-heap memory. For example, the JIT compiler requires memory for storing the native machine code translated from the JVM code for high performance.

A memory pool represents a memory area that the JVM manages. The JVM has at least one memory pool and it may create or remove memory pools during execution. A memory pool can belong to either heap or non-heap memory.

A memory manager manages one or more memory pools. The garbage collector is a type of memory manager responsible for reclaiming memory used by unreachable objects. A JVM may have one or more memory managers.

It may add or remove memory managers during execution. A memory pool can be managed by more than one memory manager. It is common to think of objects that have active references as being "alive" and un-referenced or unreachable objects as "dead. The algorithms and parameters used by GC can have dramatic effects on performance. The HotSpot VM garbage collector uses generational garbage collection.

Generational GC takes advantage of the observation that, in practice, most programs create:. So, generational GC divides memory into several generations , and assigns each a memory pool.

When a generation uses up its allotted memory, the VM performs a partial garbage collection also called a minor collection on that memory pool to reclaim memory used by dead objects. This partial GC is usually much faster than a full GC.

The HotSpot VM defines two generations: the young generation sometimes called the "nursery" and the old generation. The young generation consists of an "eden space" and two "survivor spaces.

When it performs a minor GC, the VM moves any remaining objects from the eden space to one of the survivor spaces. JConsole uses a tree to display the MBeans, allowing you to easily navigate to the MBean of interest. JConsole is bundled with the JDK.

For example, you cannot see a long description of an attribute in JConsole. You can also select JConsole from the Start menu if Windchill shortcuts are installed. For detailed instructions on using JConsole to manage and monitor applications, use the following URL:.

After you start JConsole, you can see the list of Java processes that are running locally under the current user ID and that are configured to allow JMX connections. The window presented is similar to the following:.

Each line displayed in the table indicates the process ID and the main Java class that is being run. In this example, the server manager and method server are easily identifiable by their class names. The Tomcat process is now listed under individual method servers as Tomcat is embedded in each method server.

For Tomcat process details, see the Catalina node under the method server. Select the process you want to manage and then click Connect. When connecting to a Windchill method server, a display similar to the following opens:.

From this tab, you can verify that any parameters you specified through the xconfmanager utility were correctly applied and that the machine is not running out of memory.

In the example connection dialog shown in Figure , you can see that the Anagrams application has been selected by clicking on it, but the Connect button remains grayed-out and a note has appeared informing you that the management agent is not enabled for this process. JConsole cannot connect to Anagrams because it was not started with the correct Java VM or with the correct options.

When the connection dialog opens, you are also given the option of connecting to a remote process. User name and password: the user name and password to use required only if monitoring a Java VM through a JMX agent that requires password authentication. For information about user names and passwords, see Using Password and Access Files.

The syntax of a JMX service URL requires that you provide the transport protocol used to make the connection, as well as a service access point. If the JMX agent uses a connector which is not included in the Java platform, you need to add the connector classes to the class path when you run the jconsole command, as follows. In the command above, connector-path is the directory or the Java archive Jar file containing the connector classes that are not included in the JDK, that are to be used by JConsole.

You can use the green connection status icon in the upper right-hand corner of JConsole at any time, to disconnect from or reconnect to a running Java VM. You can connect to any number of running Java VMs at a time by selecting Connection then New Connection from the drop-down menu. The Overview tab displays graphical monitoring information about CPU usage, memory usage, thread counts, and the classes loaded in the Java VM, all in a single screen.

The Overview tab provides an easy way to correlate information that was previously only available by switching between multiple tabs. To save data from a chart, simply right-click on any chart, select Save data as You can save the data from any of the charts displayed in any of JConsole's different tabs in this way.

The CSV format is commonly used for data exchange between spreadsheet applications. The CSV file can be imported into spreadsheet applications and can be used to create diagrams in these applications. The data is presented as two or more named columns, where the first column represents the time stamps. The chart shows the memory use of the Java VM over time, for heap and non-heap memory, as well as for specific memory pools. The memory pools available depend on which version of the Java VM is being used.

Survivor Space heap : The pool containing objects that have survived the garbage collection of the Eden space. Tenured Generation heap : The pool containing objects that have existed for some time in the survivor space. Permanent Generation non-heap : The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas. Code Cache non-heap : The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

You can display different charts for charting the consumption of these memory pools by choosing from the options in the Chart drop-down menu. Also, clicking on either of the Heap or Non-Heap bar charts in the bottom right-hand corner will switch the chart displayed.

Finally, you can specify the time range over which you track memory usage by selecting from the options in the Time Range drop-down menu. For more information about these memory pools, see Garbage Collection below. Used : the amount of memory currently used, including the memory occupied by all objects, both reachable and unreachable. Committed : the amount of memory guaranteed to be available for use by the Java VM. The amount of committed memory may change over time.

The Java virtual machine may release memory to the system and the amount of committed memory could be less than the amount of memory initially allocated at start up. The amount of committed memory will always be greater than or equal to the amount of used memory.

Max : the maximum amount of memory that can be used for memory management. Its value may change or be undefined. A memory allocation may fail if the Java VM attempts to increase the used memory to be greater than committed memory, even if the amount used is less than or equal to max for example, when the system is low on virtual memory. GC time : the cumulative time spent on garbage collection and the total number of invocations. It may have multiple rows, each of which represents one garbage collector algorithm used in the Java VM.

The bar chart on the lower right-hand side shows the memory consumed by the memory pools in heap and non-heap memory. The bar will turn red when the memory used exceeds the memory usage threshold. You can set the memory usage threshold through an attribute of the MemoryMXBean. Heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays.

The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects. Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM.

The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it.

Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

In addition to the method area, a Java VM may require memory for internal processing or optimization which also belongs to non-heap memory. A memory pool represents a memory area that the Java VM manages.

The Java VM has at least one memory pool and it may create or remove memory pools during execution. A memory pool can belong either to heap or to non-heap memory. A memory manager manages one or more memory pools. The garbage collector is a type of memory manager responsible for reclaiming memory used by unreachable objects. A Java VM may have one or more memory managers. It may add or remove memory managers during execution. A memory pool can be managed by more than one memory manager.

Garbage collection GC is how the Java VM frees memory occupied by objects that are no longer referenced. It is common to think of objects that have active references as being "alive" and non-referenced or unreachable objects as "dead. The algorithms and parameters used by GC can have dramatic effects on performance.

Generational GC takes advantage of the observation that most programs conform to the following generalizations. Generational GC divides memory into several generations, and assigns one or more memory pools to each. When a generation uses up its allotted memory, the VM performs a partial GC also called a minor collection on that memory pool to reclaim memory used by dead objects.

This partial GC is usually much faster than a full GC. The Java HotSpot VM defines two generations: the young generation sometimes called the "nursery" and the old generation. The young generation consists of an "Eden space" and two "survivor spaces.

When it performs a minor GC, the VM moves any remaining objects from the Eden space to one of the survivor spaces. The VM moves objects that live long enough in the survivor spaces to the "tenured" space in the old generation.

When the tenured generation fills up, there is a full GC that is often much slower because it involves all live objects. The permanent generation holds all the reflective data of the virtual machine itself, such as class and method objects. The default arrangement of generations looks something like Figure If the garbage collector has become a bottleneck, you can improve performance by customizing the generation sizes. Using JConsole, you can investigate the sensitivity of your performance metric by experimenting with the garbage collector parameters.

For more information, see Tuning Garbage Collection with the 5. The Threads list in the lower left corner lists all the active threads. If you enter a string in the Filter field, the Threads list will show only those threads whose name contains the string you enter.

Click on the name of a thread in the Threads list to display information about that thread to the right, including the thread name, state, and stack trace. The Threading MXBean provides several other useful operations that are not covered by the Threads tab. This operation returns an array of deadlocked thread IDs. This includes the name, stack trace, and the monitor lock that the thread is currently blocked on, if any, and which thread is holding that lock, as well as thread contention statistics.

This MXBean lists all the attributes and operations for accessing threading information in the Java VM being monitored.

See Monitoring and Managing MBeans. To check if your application has run into a deadlock for example, your application seems to be hanging , deadlocked threads can be detected by clicking on the "Detect Deadlock" button. If any deadlocked threads are detected, these are displayed in a new tab that appears next to the "Threads" tab, as shown in Figure The Detect Deadlock button will detect deadlock cycles involving object monitors and java. Monitoring support for java.

JConsole will not show any deadlocks related to ownable synchronizers. See the API documentation for java. Thread for more information about threads and daemon threads. The Details section at the bottom of the tab displays the total number of classes loaded since the Java VM started, the number currently loaded and the number unloaded.

You can set the tracing of class loading to verbose output by checking the checkbox in the top right-hand corner. The Hotspot VM uses adaptive compilation, in which the VM launches an application using a standard interpreter, but then analyzes the code as it runs to detect performance bottlenecks, or "hot spots". Total threads started : Total number of threads started since Java VM started, including daemon, non-daemon, and terminated threads.

Total classes loaded : Total number of classes loaded into memory since the Java VM started, including those that have subsequently been unloaded. Total classes unloaded : Number of classes unloaded from memory since the Java VM started. Garbage collector : Information about garbage collection, including the garbage collector names, number of collections performed, and total time spent performing GC.

Committed virtual memory : Amount of virtual memory guaranteed to be available to the running process. VM arguments : The input arguments the application passed to the Java VM, not including the arguments to the main method.

Class path : The class path that is used by the system class loader to search for class files. Boot class path : The boot class path is used by the bootstrap class loader to search for class files.

The MBeans tab allows you to access the full set of the platform MXBean instrumentation, including that which is not visible in the other tabs. In addition, you can monitor and manage your application's MBeans using the MBeans tab. The tree on the left shows all the MBeans currently running.

When you select an MBean in the tree, its MBeanInfo and its MBean Descriptor are both displayed on the right, and any attributes, operations or notifications appear in the tree below it. By default, the MBeans are displayed in the tree based on their object names. The order of key properties specified when the object names are created is preserved by JConsole when it adds MBeans to the MBean tree. The exact key property list that JConsole will use to build the MBean tree will be the one returned by the method ObjectName.

However, relying on the default order of the ObjectName key properties can sometimes lead to unexpected behavior when JConsole renders the MBean tree. For example, if two object names have similar keys but their key order differs, then the corresponding MBeans will not be created under the same node in the MBean tree.

As far as the JMX technology is concerned, these objects will be treated in exactly the same way. The order of the keys in the object name makes no difference to the JMX technology. To avoid this problem, you can specify the order in which the MBeans are displayed in the tree by supplying an ordered key property list when you start JConsole at the command line. This is achieved by setting the system property com. The key property list system property takes a comma-separated list of keys, in the order of your choosing, where key must be a string representing an object name key or an empty string.

If a key specified in the list does not apply to a particular MBean, then that key will be discarded. If an MBean has more keys than the ones specified in the key property list, then the key order defined by the value returned by ObjectName. Therefore, specifying an empty list of keys simply means that JConsole will display keys in the order they appear in the MBean's ObjectName. So, returning to the example of the Triangle MBeans cited above, you could choose to start JConsole specifying the keyPropertyList system property, so that all your MBeans will be grouped according to their side key property first, and their name key property second.

To do this, you would start JConsole with the following command. Starting JConsole with this system property specified would produce the MBean tree shown in Figure In Figure , the side key comes first, followed by the name key.

The type key comes at the end because it was not specified in the key property list, so the MBean tree algorithm applied the original key order for the remaining keys. Consequently, the type key is appended at the end, after the keys which were defined by the keyPropertyList system property.

According to the object name convention defined by the JMX Best Practices Guidelines , the type key should always come first. So, to respect this convention you should start JConsole with the following system property. See Using JConsole for more information on jconsole's functionality and the jconsole command-line tool documentation for jconsole's command-line options. To contribute to JConsole, make sure you read the page explaining how to contribute to the OpenJDK project, and follow the rules and guidelines described there.

You will find out that there can be many ways to contribute: one of them is to contribute to the quality. JConsole doesn't contain native code. It's a pure java tool.

It is also possible to build and test JConsole with Ant, using the build. However, you will need to download and install Apache Ant version 1. Introduction The jconsole tool is a JMX-compliant graphical tool for monitoring a Java virtual machine.
