解决

pinpoint收集程序跑在docker容器中，在暴露pinpoint收集器端口时，没有区分通信协议，导致数据不能被收集器收集。
pinpoint收集器端口，其中profiler.collector.span.port=29996和profiler.collector.stat.port=29995需要走upd协议；profiler.collector.tcp.port=29994走tcp协议。

profiler.collector.span.ip=${profiler.collector.ip}
profiler.collector.span.port=29996
profiler.collector.stat.ip=${profiler.collector.ip}
profiler.collector.stat.port=29995
profiler.collector.tcp.ip=${profiler.collector.ip}
profiler.collector.tcp.port=29994
