                  	ReportingInterval time.Duration
                  
                  	// MetricsLogFile is path where exported metrics are logged.
                  	// If it is nil then the metrics are logged on console
                  	MetricsLogFile string
                  
                  	// TracesLogFile is path where exported span data are logged.
