JVM-MANAGEMENT-MIB Table View

The Memory Manager Table contains the whole list of Memory 
Managers  as returned by ManagementFactory.getMemoryManagerMXBeans(). 
          
When a MemoryManagerMXBean object is an instance of 
GarbageCollectorMXBean, then additional information specific to 
the GarbageCollectorMXBean class will be found in the 
jvmGCTable, at the same index. 
          
Relationships between MemoryManagers and MemoryPools are shown 
by the Memory Manager-Pool Relation table (jvmMemMgrPoolRelTable).

jvmMemManagerEntry row .1.3.6.1.4.1.42.2.145.3.163.1.1.2.100.1

A jvmMemManagerEntry conceptual row represent an instance of the
java.lang.management.MemoryManagerMXBean interface. If that instance
is also an instance of java.lang.management.GarbageCollectorMXBean,

The Garbage Collector table provides additional information 
on those MemoryManagers which are also GarbageCollectors. 
This table extends the  jvmMemManagerTable table. The index 
used in the jvmMemGCTable table is imported from the 
jvmMemManagerTable table. If a row from the jvmMemManagerTable 
table is deleted, and if it has an extension in the jvmMemGCTable 
table, then the extension row will also be deleted.

jvmMemGCEntry row .1.3.6.1.4.1.42.2.145.3.163.1.1.2.101.1

Columnar objects in this table are mapped from the

The Memory Manager-Pool Relation Table shows the 
Memory Manager / Memory Pool relations, as returned by 
MemoryPoolMXBean.getMemoryManagerNames() and 
MemoryManagerMXBean.getMemoryPoolNames(). 
This table imports the indexes from the jvmMemManagerTable table 
and jvmMemPoolTable table. The jvmMemMgrRelManagerName and 
jvmMemMgrRelPoolName objects are not actually necessary since 
the indexes are self-sufficient to express the relationship - 
but the names  will make the table more understandable when displayed 
in a management console.
