python实现skywalking的trace模块过滤和报警(实例代码)
作者：Shy01
Skywalking可以对链路追踪到数据进行告警规则配置，例如响应时间、响应百分比等。发送警告通过调用webhook接口完成。webhook接口用户可以自定义。本文给大家介绍python实现skywalking的trace模块过滤和报警，感兴趣的朋友跟随小编一起看看吧
skywalking本身的报警功能，用起来视乎不是特别好用，目前想实现对skywalking的trace中的错误接口进行过滤并报警通知管理员和开发。所以自己就用python对skywalking做了二次数据清洗实现。项目方在了自己了github（https://github.com/shygit-dev/skywalking-cli-python）上了，有兴趣的同学可以做二次改造，共同学习。下面简单列出了代码内容：
