[jira] [Created] (NIFI-2194) AmbariReportingTask should cache metrics

Bryan Bende created NIFI-2194:
---------------------------------

             Summary: AmbariReportingTask should cache metrics
                 Key: NIFI-2194
                 URL: https://issues.apache.org/jira/browse/NIFI-2194
             Project: Apache NiFi
          Issue Type: Improvement
    Affects Versions: 0.6.1
            Reporter: Bryan Bende
            Assignee: Bryan Bende
            Priority: Minor
             Fix For: 1.0.0


The Ambari Metrics Collector expects clients to perform some amount of caching/aggregation before sending metrics. This is typically done by using the TimelineMetricsCache provided in ambari-commons. The AmbariReportingTask should use this to properly send metrics.

In addition many applications sending metrics extend AbstractTimelineMetricsSink [1]. It is not required to do so, but may be useful here.
