> Problem in precision handling of metrics returned by AMS
> --------------------------------------------------------
>
> Key: AMBARI-13411
> URL: https://issues.apache.org/jira/browse/AMBARI-13411
> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics
> Affects Versions: 2.1.2
> Reporter: Siddharth Wagle
> Assignee: Aravindan Vijayan
> Priority: Critical
> Fix For: 2.1.3
>
>
> Bug
> The metrics data returned by Ambari that is displayed on the charts seems to
> have different granularity for different periods in a single time series on a
> chart.
> Problem
> The AMS cache layer running on the Ambari server requests the metrics data
> only for the delta period (period for which the data is not present in the
> cache) to the AMS. The bug was that the precision of the data requested (or
> computed) was not taken into account during this delta request.
> Objective of this patch
> Incorporate the difference between precision of the data in the cache and the
> requested precision of the data while requesting from AMS.
