Description copied from interface: SampleRepository

Returns measurements for a set of metrics, a given resource, and a time range.

Passing a null value for start or end serves to make that end of the temporal range unbounded. For example, a null start will return all matching measurements up to the end Timestamp. Passing both a null start and end will return all measurements for the matching metrics (so be careful).

Note: There is no guarantee that a sample period will include results for every requested metric (or any of them, in fact); Missing samples are recorded with a value of Double.NaN.

Specified by:

find in interface SampleRepository

start - the start time of this search.

end - the end time of this search.

resource - the resource to query.

metrics - a sequence of metrics to include in the results.

Returns:

a Results instance containing the results of the search.
