 NOTE: You must have [enabled logging at the debug level](https://kiali.io/docs/configuration/kialis.kiali.io/#.spec.deployment.logger.log_level) to see the above message in the logs.
 
 This should work with the other credentials that can be read from a mounted secret. They all need to be mounted as a file called `value.txt` that goes into their own sub-directory under `/kiali-override-secrets` - one of:
+* grafana-username
 * grafana-password
 * grafana-token
+* prometheus-username
 * prometheus-password
 * prometheus-token
+* tracing-username
 * tracing-password
 * tracing-token
 * login-token-signing-key
+* customdashboards-prometheus-username
+* customdashboards-prometheus-password
+* customdashboards-prometheus-token
 
 So, for example, if you are mounting a custom secret for the Grafana token, the mount location should be declared as `/kiali-override-secrets/grafana-token`.
