BT Base Line Configuration options
I'm trying to find some documentation on the Base Line Configuration option dialog in the BT editor. We use quite a few BTs in our Application Overview and alert on them when baseline violations occur.
I'd like to modify how a baseline violation is triggered... and I think it's done here, but I'm not able to find any documentation about what 'Relative Deviation' and 'Absolute Deviation' mean. Do they both have to happen for a violation to trigger? Is it possible to just use a % number? (for example for failure rate – it has to be 100% worse than the baseline before a violation is triggered)
Sorry it took some time, Scott,
so I would assume if your response time base line is at 100 ms, with a 20 % relative deviation an incident should be triggered with a significant violation *) above 120 ms; with 100 % at > 200 ms.
If you leave the absolute deviation at 50 ms an incident should be triggered with a significant violation *) at > 150 ms.
*) see Baseline and Smart Alerting Explained - Response Time (chart)
Hope this helps

Thank Guenter.
Lets say I change the Relative Deviation from 20% to 100%, what is the end result for Response Time? Does that mean it will only alert if the detected baseline violation was at least 100% or greater?
Do I also have to change the Absolute deviation as well?
Hi Scott,
I finally got around to add this dialog and and a short description (and a path to it!) to Business Transaction Details and Baseline and Smart Alerting Explained – where it was missing to clarify things.
Thanks
G.
I read through those pages, but I wasn't able to find what I was looking for. Nothing around how we can contol how an alert is triggered. I'm guessing its around the significant measurements?
Here's the dialog that I'm interested in configuring. It's really the violation detection settings dialog. Sorry for the misleading title.
Have you looked at´Application Monitoring and especially Baseline and Smart Alerting Explained?
There is also an explanation on the baseline settings here: Business Transaction Details
I hope this helps
