    scheme: https
    static_configs:
      - targets: ['sap.leonardo.example:443']
    tls_config:
      ca_file: '/path/to/ca.pem'
      cert_file: '/path/to/cert.pem'
      key_file: '/path/to/key.pem'

 

  • **Authentication**: Enable OAuth2 or use JWT tokens for authenticating requests between SAP Leonardo and Prometheus to prevent unauthorized access.
