It depends.

On can distinguish OS and architecture by conditional compilation. For some intro have a look at: [https://dave.cheney.net/2013/10/12/how-to-use-conditional-compilation-with-the-go-build-tool](https://dave.cheney.net/2013/10/12/how-to-use-conditional-compilation-with-the-go-build-tool)

A many used packages (from stdlib) have a unified interface and use conditional compilation -\> no special handling required in filebeat.

Sometimes it's easier just to dynamically check. One can use `runtime.GOOS` to check if the binary is running on windows.
