getOperatingSystemMXBean
public static OperatingSystemMXBean getOperatingSystemMXBean()
- Returns the operating system management bean for the
operating system on which the virtual machine is running.
- Returns:
- an instance of
OperatingSystemMXBean for
the underlying operating system.
getRuntimeMXBean
public static RuntimeMXBean getRuntimeMXBean()
- Returns the runtime management bean for the
running virtual machine.
- Returns:
- an instance of
RuntimeMXBean for
this virtual machine.
getClassLoadingMXBean
public static ClassLoadingMXBean getClassLoadingMXBean()
- Returns the class loading management bean for the
running virtual machine.
- Returns:
- an instance of
ClassLoadingMXBean for
this virtual machine.
getThreadMXBean
public static ThreadMXBean getThreadMXBean()
- Returns the thread management bean for the running
virtual machine.
- Returns:
- an instance of
ThreadMXBean for
this virtual machine.
getMemoryMXBean
public static MemoryMXBean getMemoryMXBean()
- Returns the memory management bean for the running
virtual machine.
- Returns:
- an instance of
MemoryMXBean for
this virtual machine.
getCompilationMXBean
public static CompilationMXBean getCompilationMXBean()
- Returns the compilation bean for the running
virtual machine, if supported. Otherwise,
it returns
null .
- Returns:
- an instance of
CompilationMXBean for
this virtual machine, or null
if the virtual machine doesn't include
a Just-In-Time (JIT) compiler.
getMemoryPoolMXBeans
public static List<MemoryPoolMXBean> getMemoryPoolMXBeans()
- Returns the memory pool beans for the running
virtual machine. These may change during the course
of execution.
- Returns:
- a list of memory pool beans, one for each pool.
getMemoryManagerMXBeans
public static List<MemoryManagerMXBean> getMemoryManagerMXBeans()
- Returns the memory manager beans for the running
virtual machine. These may change during the course
of execution.
- Returns:
- a list of memory manager beans, one for each manager.
getGarbageCollectorMXBeans
public static List<GarbageCollectorMXBean> getGarbageCollectorMXBeans()
- Returns the garbage collector beans for the running
virtual machine. These may change during the course
of execution.
- Returns:
- a list of garbage collector beans, one for each pool.
getPlatformMBeanServer
public static MBeanServer getPlatformMBeanServer()
Returns the platform MBeanServer . On the
first call to this method, a server instance is retrieved from
the MBeanServerFactory and each of the
beans are registered with it. Subsequent calls return the existing
instance. If the property javax.management.builder.initial
is set, its value will be used as the name of the class which is used
to provide the server instance.
It is recommended that the platform server is used for other beans as
well, in order to simplify their discovery and publication. Name conflicts
should be avoided.
- Returns:
- the platform
MBeanServer
- Throws:
SecurityException - if a security manager exists and the
caller's permissions don't imply MBeanServerPermission(String) ("createMBeanServer")- See Also:
MBeanServerFactory ,
MBeanServerFactory.createMBeanServer()
newPlatformMXBeanProxy
public static <T> T newPlatformMXBeanProxy(MBeanServerConnection connection,
String mxbeanName,
Class<T> mxbeanInterface)
throws IOException
Returns a proxy for the specified platform bean. A proxy object is created
using Proxy.newProxyInstance(mxbeanInterface.getClassLoader(),
new Class[] { mxbeanInterface }, handler) . The
NotificationEmitter class is also added to the
array if the bean provides notifications. handler refers
to the invocation handler which forwards calls to the connection, and
also provides translation between the Java data types used in the
bean interfaces and the open data types, as specified in the description
of this class. It is this translation that makes the
usual MBeanServerInvocationHandler inappropriate
for providing such a proxy.
Note: use of the proxy may result in
IOException s from the underlying MBeanServerConnection
and a InvalidObjectException if enum constants
used on the client and the server don't match.
- Parameters:
connection - the server connection to use to access the bean.mxbeanName - the ObjectName of the
bean to provide a proxy for.mxbeanInterface - the interface for the bean being proxied.
- Returns:
- a proxy for the specified bean.
- Throws:
IllegalArgumentException - if mxbeanName is not a valid
ObjectName ,
the interface and name do not match the
same bean, the name does not refer to a
platform bean or the bean is not registered
with the server accessed by connection .
IOException - if the connection throws one.
