Review Request 34292: AMS: Incorrect value obtained for a datapoint in the metric data queried from AMS

Review request for Ambari, Alejandro Fernandez, Billie Rinaldi, Dmytro Sen, and Sumit Mohanty.


Bugs: AMBARI-11184
    https://issues.apache.org/jira/browse/AMBARI-11184


Repository: ambari


Description
-------

http://104.196.88.124:8080/api/v1/clusters/c1/services/YARN/components/RESOURCEMANAGER?fields=metrics/yarn/ClusterMetrics/NumActiveNMs._sum[1431372267,1431375867,15]&_=1431375867 

Above is an API to return series data for number of active nodemanagers in the asked time interval. Although the cluster has only 1 nodemanager installed, a specific datapoint had 2 as a value which is incorrect.
*NOTE: Since there is only 1 nodemanager installed, the valid set of values at any time is {0,1}.* 

http://c6401.ambari.apache.org:8080/api/v1/clusters/test_widg/services/ACCUMULO/components/ACCUMULO_TSERVER?fields=metrics/tserver/general/entries._max
for _max, _min, _sum, and _avg are returning the same value.  The metrics_aggregate table in phoenix looks like it has correct values for the sum, max, and min, but I appear to only be getting back the value from a single host component through the rest API.

Just to highlight 2 minute separation makes unit test more readable.

This is a general problem, we  haven't solved this one anywhere.

    Does this need to check for wraparound due to the sum?

    Why is this multiplying by 2?

Review request for Ambari, Alejandro Fernandez, Billie Rinaldi, Dmytro Sen, and Sumit Mohanty.


Changes
-------

Setting timeslice interval to 30 seconds and server time shift to 90, to get good results for cluster aggregates.


Bugs: AMBARI-11184

Review request for Ambari, Alejandro Fernandez, Billie Rinaldi, Dmytro Sen, and Sumit Mohanty.


Changes
-------

Removed timeshifting client side timestamps to adding a configurable timeshift to the server time.

Bugs: AMBARI-11184
    https://issues.apache.org/jira/browse/AMBARI-11184


Repository: ambari


Description
-------

http://104.196.88.124:8080/api/v1/clusters/c1/services/YARN/components/RESOURCEMANAGER?fields=metrics/yarn/ClusterMetrics/NumActiveNMs._sum[1431372267,1431375867,15]&_=1431375867 

Above is an API to return series data for number of active nodemanagers in the asked time interval. Although the cluster has only 1 nodemanager installed, a specific datapoint had 2 as a value which is incorrect.
*NOTE: Since there is only 1 nodemanager installed, the valid set of values at any time is {0,1}.* 

http://c6401.ambari.apache.org:8080/api/v1/clusters/test_widg/services/ACCUMULO/components/ACCUMULO_TSERVER?fields=metrics/tserver/general/entries._max
for _max, _min, _sum, and _avg are returning the same value.  The metrics_aggregate table in phoenix looks like it has correct values for the sum, max, and min, but I appear to only be getting back the value from a single host component through the rest API.
