skywalking版本：v6.0.0-GA
参考文档：https://github.com/apache/skywalking/blob/6.x/docs/en/setup/backend/trace-sampling.md
按照官方设置的服务端trace信息的采样率为5000，数据量未降下来
修改的配置文件名：apache-skywalking-apm-incubating-bin/config/application.yml
配置信息如下：

It's true, it's not the same as when I used 6.6. There is also a way to dynamically configure the sampling rate, I can't find the documentation.

Why shouldn't? We never said 1 == 100% sampling.

I don't know what is the difference, I don't remember anyone changed this. The dynamic configuration document is in the backend setup. If I remember correctly, the sampling rate could be changed in the next release or master.

@MichaelWangHong All GitHub discussions must be in English. And your description doesn't match this issue at all, and your version is years ago, the community doesn't take care of it anymore.
