getMetrics

ApiMetricList getMetrics(clusterName, nameservice, serviceName, from, metrics, to, view)

Fetch metric readings for a particular nameservice.

Fetch metric readings for a particular nameservice.

By default, this call will look up all metrics available. 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, even if no readings are available in the requested window.
