#values(start_time, ndatapoints) ⇒ Object

Get a set of datapoints back for an instrumentation use start_time and ndatapoints so we can get back a range of datapoints the interval between datapoints should correspond to the granularity of the instrumentation

Parameters:

  • start_time (Time)
  • ndatapoints (Integer)
