> PROBLEM
> Storm cluster metrics (aggregated across hosts) don't show up in Ambari and
> Grafana
> BUG
> Storm metrics collect and send data in 1 minute intervals. Since their data
> is present in the right end of the spectrum for the 2 minute aggregator
> (start_time ~ server_time), a bug in the second aggregator is causing these
> values to slip between 2 aggregator cycles.
> FIX
> Within the 2 minute interval, look for the data in the time shifted interval
> ( ams-site:timeline.metrics.service.cluster.aggregator.timeshift.adjustment).
> In case no data is present, look for the data outside the right boundary of
> the interval. Use that to interpolate the data in the 30second slices.
