Fetch metric readings for a particular service.
By default, this call will look up all metrics available for the service. If only specific metrics are desired, use the metrics parameter.
By default, the returned results correspond to a 5 minute window based on the provided end time (which defaults to the current server time). The from and to parameters can be used to control the window being queried. A maximum window of 3 hours is enforced.
When requesting a "full" view, aside from the extended properties of the returned metric data, the collection will also contain information about all metrics available for the service, even if no readings are available in the requested window.
HDFS services from CDH4 that have more than one nameservice will not expose any metrics. Instead, the nameservices should be queried separately.
