Field Summary

static String	CPU The namespace for counters dealing with processor(s) (CPU).
static String	Info The namespace for counters describing the host platform.
static String	LogicalDisk The namespace for counters dealing with logical aggregations of disk.
static String	Memory The namespace for counters dealing with memory (RAM).
static String	Memory_GarbageCollectors The namespace for counters dealing with garbage collection (GC is per-JVM and is therefore reported for each service, so this namespace is relative to the counter set for the service).
static String	PhysicalDisk The namespace for counters dealing with physical disks.
static String	ps The path separator string.
