The baseline is calculated over a 7 day rolling window. The calculation starts immediately and gets more refined over time until it can finally compare the current Monday to the previous Monday when it has a week of data. Low/High Traffic problems will not be raised until a week has passed since initial data collection for the application/service. Response Time and Failure problems will be raised after 20% of a week.

Relative and Absolute refer to thresholds set based on the deviation from the baseline, not the baseline itself.

An example of absolute would be 100 ms. An example of relative would be 50%.

Absolute means a concrete number. Relative means a percentage increase.
