However, it is common to use an integration or community project where rules / dashboards are provided for you.  Oftentimes, this provided assets use hard-coded values for a job label i.e. `...{job="integrations/kubernetes/cadvisor"...}` or `...{job="minio-job"...}` setting this annotation to that value will allow the provided asset to work out of the box. |
