Hi Srujun, Metrics reporting should be supported independent of the deployment model. Can you please attach your container log file?
Are you seeing log lines from MetricsSnapshotReporter: https://github.com/apache/samza/blob/master/samza-core/src/main/scala/org/apache/samza/metrics/reporter/MetricsSnapshotReporter.scala ? Alternately, you could also set your log-level to DEBUG and verify if the snapshot reporter is being invoked. Best, Jagdish
