public interface MetricsRegistry
Metric
s and
have those metrics wired to specific metrics systems, such as JMX, provided by MetricsReporter
s.
Those implementing Samza jobs use the MetricsRegistry to register metrics, which then handle
the details of getting those metrics to each defined MetricsReporter.
Users are free to define their metrics into groups as needed for their jobs. MetricsReporter
s
will likely use the group field to group the user-defined metrics together.Modifier and Type | Method and Description |
