> When querying a large number of Hosts, AMS API returns a truncated set of data-points.
The number of data-points is 
> Metrics service default result limit / no. of hosts
> If the Metrics service default result limit is set to 15840 (current default), then for
900 hosts, the data-points that will be returned for each host will be 18..
