Don’t put too many metrics in one group
Especially for critical metrics, if you have many metrics in the group and one critical metric fails, but the rest pass, the group gets a passing score overall.
You can put a critical metric in a group of only one to ensure that if it fails, the whole group fails every time.
Some configuration values to start with
Although these values are not necessarily “best practices,” they are reasonable starting points for your canary configs:
|canary lifetime||3 hours|
|warmup period||0 minutes|
