进程可以注册多少个提供商？ [英] How many providers can a process register?

问题描述

是否有关于进程可以注册的计数器集提供程序数量的指导（即PerfStartProvider函数）？在EventRegister函数中，它提到"一个进程最多可以注册1,024个提供者GUID;但是，您应该将进程注册的提供程序数限制为一个或两个。"对于计数器集提供者来说，这也是正确的吗？

谢谢，
恒恒

Is there a guidance on number of counter set providers that a process can register (i.e. PerfStartProvider function)? In the EventRegister function, it mentions "A process can register up to 1,024 provider GUIDs; however, you should limit the number of providers that your process registers to one or two.". Is this also true for the counter set provider?

Thanks,

推荐答案

鉴于此单个用户模式proider可以定义多个计数器集，组件不应该需要多于1个提供者。在Win7 1024之前是限制。从Win7开始，限制是可用的系统资源（句柄，内存等）。

Given that a single user mode proider can define multiple counter sets a component should not need more then 1 provider. Before Win7 1024 is the limit. Starting with Win7 the limit is available system resources (handles, memory, etc....).
