Please note all the arguments are optional. If you do not specify these arguments, default values will be used:

• host and serverPort will be “localhost:50051”
• user will be “world”
• cloudProjectId will be null (which means no stats/spans will be exported to Stackdriver)
• server zPagePort will be 3000
• client zPagePort will be 3001
• Prometheus port will be 9090

However, if you want to specify any of these arguements, please make sure they are in order.
