Method Detail

getProcessPhysical

MemoryData[] getProcessPhysical()

Gets the amount of physical memory (RAM) that is currently in use by the monitored process. On some platforms, this memory is called "resident storage" or the "working set".

Returns:

an array of MemoryData of the process physical memory. This is all the data available over time and not just the most recent.

getProcessVirtual

MemoryData[] getProcessVirtual()

Gets the total process address space in use.

Returns:

an array of MemoryData of the process virtual memory. This is all the data available over time and not just the most recent.

getProcessPrivate

MemoryData[] getProcessPrivate()

Gets the amount of memory that is used exclusively by the monitored process. This memory is not shared with other processes on the system.

Returns:

an array of MemoryData of the process private memory in use. This is all the data available over time and not just the most recent.

getFreePhysicalMemory

MemoryData[] getFreePhysicalMemory()

Gets the amount of physical memory (RAM) that is free on the monitored system.

Returns:

an array of MemoryData of how much free memory there is. This is all the data available over time and not just the most recent.

getTotalPhysicalMemory

MemoryData[] getTotalPhysicalMemory()

Gets the total amount of installed physical memory.

Returns:

an array of MemoryData of the amount of installed memory. This is all the data available over time and not just the most recent.

getNativeMemoryRoot

NativeMemoryCategory getNativeMemoryRoot()

Gets the object at the root of the hierarchy of native memory categories. The highest-level category is JRE. For more information, see the NativeMemoryCategory class.

Returns:

the object at the root of the native memory hierarchy.
