How do we compute canary deviation


When the canary runs for a given interval, all the metrics are evaluated and each metric is given a pass/fail based on the deviation from the baseline metric.

How do we know about deviation,for example

memory used
base 1000M
canary 1003M

Kayenta tell me the result is false.I don’t know ?


me too :face_with_raised_eyebrow:


Do you have a graph of the metrics over time? Kayenta compares two time series of data, not just a pair of points. Seeing what the metrics behave like over time is useful for understanding whether or not they are similar.
