I have a questions related to automatic threshold baseline and also relative and absolute threshold. The first questions is that how dynatrace calculate the automatic baseline, is the learning time is 7 days ? And what is exactly relative and absolute threshold, i can understand how do they calculate, but i coduln't understand exactly what these are ? Can you clarify me ? Thank you.
Solved! Go to Solution.
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.

Hope this helps,
So, focusing on Response Time, absolute theshold means that if the response time of baseline in the last 7 days exceded of 100ms it raises an alert, right?
And, for example, if we increase the absolute threshold from 100ms to 1000ms, an alert was raised if the response time of the baseline exceded of 1 sec in the last 7 days, right?
