public class HttpFSServerMetrics
extends Object

This class is for maintaining the various HttpFSServer statistics and publishing them through the metrics interfaces. This also registers the JMX MBean for RPC.

This class has a number of metrics variables that are publicly accessible; these variables (objects) have methods to update their values; for example:

bytesRead.inc()
