For USDT probes, you can specify only the provider and name portions of this specification.
对于USDT探测，可以只指定其中的provider和name部分。
For your own applications, you can address this by using the User-land Statically Defined Tracing (USDT).
对于自己的应用程序，可以使用User - land Statically DefinedTracing (USDT)解决这个问题。
USDT enables you as a developer to add specific probes to your application at points in the code that you have identified as significant.
USDT 让开发人员可以在代码中重要的位置添加特定的探测。
If you are adding USDT probes, you should be creating probes according to the operational points you want to probe, not the function boundaries.
如果要添加usdt探测，应该在希望探测的操作点上创建探测，不应该在函数边界上。
The USDT system also enables you to expose data from your running application, which can be accessed as arguments to the probes when tracing the application.
还可以使用 USDT从正在运行的应用程序获取数据，这些数据可作为跟踪应用程序的探测的参数而被访问。
Before you start adding USDT probes to your system, you first need to consider what you want the probes to report, what information they might provide, and the potential performance issues.
开始在系统中添加usdt探测之前，首先需要考虑想让探测报告什么、它们可能提供什么信息以及潜在的性能问题。
