> The key code line is at
> [servicecomb-java-chassis/metrics/metrics-core/src/test/java/org/apache/servicecomb/metrics/core/TestVertxMetersInitializer.java|https://github.com/apache/servicecomb-java-chassis/blob/a063df553aaa0cbdefce4c7f5aaeabba7cc1d466/metrics/metrics-core/src/test/java/org/apache/servicecomb/metrics/core/TestVertxMetersInitializer.java#L169]

> in the end of this line, the port number is filled into a place holder
> {{%-5s}}, which means if the port number is 4-digit, there will be a space at
> the end. But if a microservice instance is actually assigned a 4-digit
> portnumber, the metrics log will only write the port number without any
> unnecessary space character.
