i have 2 questions about configuration alerts for base line violations (Business Transactions > Edit BusinessTrnsaction... > Violation Detections Settings...):
1- for response time, i need trigger incidents only when relative deviation is exceeded (not absolute deviation). How do i have to configure it in Violation Detection Settings?
2- for Failure Rate, Relative Deviation and Absolute deviation are expressed as a percentage %. Whats the difference between the two?
For your second point - because failure rate is a % measure, the absolute deviation is at what number of percentage points above the current baseline do you want to alert at. So for example if your current basline is 10% failure rate and you wanted to alert if that rose to 15%, the absolute deviation would be 5%
the relative deviation would be 50%.
For point 1: I'm not sure if there's a way of disabling absolute deviation, (perhaps somebody else can answer) but as a short term measure you could always try setting this to a very high value, such that absolute deviation wouldn't be hit until relative had been breached first.
