	SecretToken string

	// ServerURLs holds the URLs for your Elastic APM Server. The Server
	// supports both HTTP and HTTPS. If you use HTTPS, then you may need to
	// configure your client machines so that the server certificate can be
	// verified. You can disable certificate verification with SkipServerVerify.

	// variables:

	// - ELASTIC_APM_SERVER_CERT: the path to a PEM-encoded TLS certificate
	//   that must match the APM Server-supplied certificate. This can be used
	//   to pin a self signed certificate.
	//
	// - ELASTIC_APM_SERVER_CA_CERT_FILE: the path to a PEM-encoded TLS
	//   Certificate Authority certificate that will be used for verifying
	//   the server's TLS certificate chain.
	//
	// - ELASTIC_APM_VERIFY_SERVER_CERT: flag to control verification of the
	//   APM Server's TLS certificates. If ELASTIC_APM_SERVER_CERT is defined,
	//   ELASTIC_APM_VERIFY_SERVER_CERT is ignored.
