Hello, I'm facing a similar issue with metrics not storing in HBase METRIC_RECORD table. I can however see the metrics being tracked since they are being returned by the /ws/v1/timeline/metrics/metadata endpoint. I have set: timeline.metrics.service.outofband.time.allowance.millis=600000 Just to give a background, I'm using StormTimelineMetricsSink to push custom topology metrics to the metrics collector & see the log statements to show that metrics are being emitted properly. Although the metric names show up in the dropdown of Grafana, there are no values to plot. I do see other other metric values showing up in the default graphs for AMS_HBASE, HOST etc. I did rm -rf hbase-tmp/ folders couple of times & started clean.
