Hi,
As per the "Traefik Architecture Overview" diagram in https://traefik.io/traefik/ page, Traefik supports Observability tooling and Canary deployment.

  1. Could you please help me in understanding that these Observability tooling and Canary deployment features are available in Community version? or supports in Enterprise edition only?
  2. Could you please provide the documentation link to those 2 features.
  3. Which version of Traefik has these 2 features?

Thanx,
Anwar
