Why we need a Dynamic Baseline and Thresholding Tool
Forewarned is forearmed the poverb goes, a quick google tells me "prior knowledge of possible dangers or problems gives one a tactical advantage". The reason we want to baseline and threshold our data is so that we can receive alerts forewarning us of issues in our environment, so that we can act to resolve smaller issues before they become bigger. Being proactive increases our Mean Time Between Failure.

In practicality this spike was brief and using the 15 minute threshold period (current is the average of the last 15 minutes) the value for calculating change would be 136 and the resulting change would be 36% so a Major event. The threshold period is dampening the spikes to remove brief changes and allow you to see changes which last longer.
