Best practices for configuring canary

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:

Setting Value
canary lifetime 3 hours
successful score 95
unhealthy score 75
warmup period 0 minutes
frequency 60 minutes
use lookback no
