Siddharth Wagle created AMBARI-12248:
----------------------------------------

             Summary: Metrics API result set contains a lot of data outside the requested
time range
                 Key: AMBARI-12248
                 URL: https://issues.apache.org/jira/browse/AMBARI-12248
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.0.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
            Priority: Critical
             Fix For: 2.1.0


When I access the Host Details page for :
{code}
http://172.22.76.13:8080/api/v1/clusters/leapsec/hosts/leapsec-rhel6-11.openstacklocal?fields=metrics/cpu/cpu_user[1436028521,1436032121,15],metrics/cpu/cpu_wio[1436028521,1436032121,15],metrics/cpu/cpu_nice[1436028521,1436032121,15],metrics/cpu/cpu_aidle[1436028521,1436032121,15],metrics/cpu/cpu_system[1436028521,1436032121,15],metrics/cpu/cpu_idle[1436028521,1436032121,15]&_=1435698892786
{code}

However, look at the screenshot. The start time (1435946268) and using the standard +3600
seconds for the end time (1435949868), the following call was made:
{code}
http://172.22.76.13:8080/api/v1/clusters/leapsec/hosts/leapsec-rhel6-11.openstacklocal?fields=metrics/cpu/cpu_user[1435946268,1435949868,15],metrics/cpu/cpu_wio[1435946268,1435949868,15],metrics/cpu/cpu_nice[1435946268,1435949868,15],metrics/cpu/cpu_aidle[1435946268,1435949868,15],metrics/cpu/cpu_system[1435946268,1435949868,15],metrics/cpu/cpu_idle[1435946268,1435949868,15]&_=1435698626557
{code}

This resulted in 13.6MB of data transferred in 12.05s.  The result set size is exactly consistent
with what is in the screenshot.
Note that this result set contained a bunch of data that are *outside* of the time window
specified [1435946268,1435949868).
