Baseline Averages

Depending on the amount of polled data that is collected, baseline averages are calculated in two ways:

Initially, as an average of the hourly averages for the same hour (regardless of day).
After enough data is collected, as an average of the hourly averages for the same day of the week, same hour.

Baseline averages help to characterize past performance for selected monitored metrics, and helps to assess present performance. Baseline averages and related standard deviations are continually calculated as each hour passes. The standard deviation provides a statistical indicator of how much variability exists in the population data that factored into the baseline average calculations.

In Data Aggregator, what is considered to be "normal" for a specified duration within a window of time is based on the calculated baseline average.
