## Metrics (`metrics`)
- `ENABLED`: **false**: Enables /metrics endpoint for prometheus.
- `ENABLED_ISSUE_BY_LABEL`: **false**: Enable issue by label metrics
- `TOKEN`: **\<empty\>**: You need to specify the token, if you want to include in the authorization the metrics . The same token need to be used in prometheus parameters `bearer_token` or `bearer_token_file`.
