          "The average response time is the mean of a number of "
          "requests captured between StatisticTime and a close point "
          "in time in the past. This interval or duration, that the "
          "average depends on, is defined by the underlying "
          "implementation such that it still has a reasonable "
          "proximity to one point in time. The term average is not "
          "focused on averaging a number of requests but averaging a "
          "period of time. Therefore, the average does not relate to "
          "more than a couple of minutes and, consequently, "
          "AverageResponseTime has the notion of the response time at "
          "the point in time of StatisticTime. If the interval is too "
          "great, AverageResponseTime becomes meaningless for "
          "monitoring. If no response time can be determined, the "
          "value is 0."),
