• Include the ambari-metrics-common artifacts from source or maven-central (when available) into your project
• Find below helpful info regarding common data-structures to use from the ambari-metrics-common module
• Extend the org.apache.hadoop.metrics2.sink.timeline.AbstractTimelineMetricsSink class and implement the required methods
• Use the org.apache.hadoop.metrics2.sink.timeline.cache.TimelineMetricsCache to store intermediate data until it is time to send (example: collection interval = 10 seconds, send interval = 1 minute). The cache implementation provides the logic needed for buffering and local aggregation.
• Use org.apache.hadoop.metrics2.sink.timeline.AbstractTimelineMetricsSink#emitMetrics to send metrics to AMS backend.
