    ## @param type_overrides - mapping - optional
    ## Override a type in the Prometheus payload or type an untyped metric (ignored by default).
    ## Supported <METRIC_TYPE> are `gauge`, `counter`, `histogram`, and `summary`.

    #
    # ssl_cert: <CERT_PATH>

    ## @param ssl_private_key - string - optional
    ## Needed if the certificate does not include the private key.
    ## WARNING: The private key to your local certificate must be unencrypted.
    #
    # ssl_private_key: <KEY_PATH>

    ## @param ssl_ca_cert - string - optional
    ## The path to the trusted CA used for generating custom certificates. Set this to false to disable SSL
