Field Summary

static String	CPU_PercentProcessorTime Percentage of the time the processor is not idle.
static String	CPU_PercentSystemTime Percentage of the time the processor is not idle that it is executing at the system (aka kernel) level (normalized to 100% in single CPU and SMP environments).
static String	CPU_PercentUserTime Percentage of the time the processor is not idle that it is executing at the user level (normalized to 100% in single CPU and SMP environments).
static String	Memory_majorFaultsPerSec Faults which required loading a page from disk.
static String	Memory_minorFaultsPerSec Faults that did not require loading a page from disk.
static String	Memory_percentMemorySize The percentage of the phsyical memory used by the process.
static String	Memory_residentSetSize The non-swapped physical memory used by the process in bytes.
static String	Memory_runtimeFreeMemory The value reported by Runtime.freeMemory() (the amount of free memory in the JVM)).
static String	Memory_runtimeMaxMemory The value reported by Runtime.maxMemory() (the maximum amount of memory that the JVM will attempt to use).
static String	Memory_runtimeTotalMemory The value reported by Runtime.totalMemory() (the amount of total memory in the JVM, which may vary over time).
static String	Memory_virtualSize The virtual memory usage of the process in bytes.
static String	PhysicalDisk_BytesReadPerSec The rate at which the process is reading data from disk in bytes per second.
static String	PhysicalDisk_BytesWrittenPerSec The rate at which the process is writing data on the disk in bytes per second (cached writes may be reported in this quantity).
