Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-15749
https://issues.apache.org/jira/browse/AMBARI-15749
Repository: ambari
Description
-------
Introduce 'diff' post processing function to compute difference between points
across time.
Modify rate calculation such that it is calculated based on the precision of
the data requested. When no explicit precision is requested from Grafana, the
precision is computed based on this :
* Time_Range <= 2 hrs : Rate per SECOND
* 2hrs < Time_Range <= 1 day : Rate per MINUTE .
* 1 day < Time_Range <= 30 days : Rate per HOUR .
* Time_Range > 30 days : Rate per DAY .
Also, removed the first point from the series during rate and diff calculation.
