然而，应用探针的方式通常是特定的。有时产生的数据需要手动增加代码来保证符合
遥测数据。而有时，探针（代理）能辅助自动收集数据。每个独特的监控方案（除了
printfc
）都有特定的自定义步骤来产生和转移符合产品后端存储的遥测数据。
过去，你可能在应用程序中安装了针对后端的探针库或代理。然后，你可以使用这些客
户端库提供的函数添加自己的自定义探针，以捕获你认为与了解应用程序的内部状态相
关的任何数据。然而，这些探针方法的产品特性也造成了“厂商锁定”。如果希望将遥
测数据发送到不同的产品，则需要使用不同的库重复整个探针过程，这将浪费代码，并
使测量开销加倍。
7.2 开源探针标准
为了解决“厂商锁定”问题，监控和可观测性社区过去几年创建了很多开源项目，比如
2016
年的
Open Tracing
（云原生计算基金会旗下）和
2017
年的
OpenCensus
（谷歌资助）。
这些有竞争力的开放标准为最流行的编程语言提供了一组库，以允许用户实时收集遥测
数据并传输到所选择的后端。最终在
2019
年，两个组织共同组建了
OpenTelemetry
项
目，并由
CNCF
负责。
标准的好处就是有了很多选择。
