public interface GarbageCollectorMXBean extends MemoryManagerMXBean
memory manager
.
A Java virtual machine may have one or more instances of
the implementation class of this interface.
An instance implementing this interface is
an MXBean
that can be obtained by calling
the ManagementFactory.getGarbageCollectorMXBeans()
method or
from the platform MBeanServer
method.
The ObjectName for uniquely identifying the MXBean for a garbage collector within an MBeanServer is:
java.lang:type=GarbageCollector
,name=collector's name
It can be obtained by calling the
PlatformManagedObject.getObjectName()
method.
A platform usually includes additional platform-dependent information
specific to a garbage collection algorithm for monitoring.ManagementFactory.getPlatformMXBeans(Class)

getCollectionCount()
Returns the total number of collections that have occurred.

getCollectionTime()
Returns the approximate accumulated collection elapsed time
in milliseconds.

long getCollectionCount()
long getCollectionTime()
The Java virtual machine implementation may use a high resolution timer to measure the elapsed time. This method may return the same value even if the collection count has been incremented if the collection elapsed time is very short.
