Done Inline ActionsThat's true -- and the error message in this particular case doesn't really seem like a great one to begin with: dtrace: invalid probe specifier fbt::vn_sendfile:return { trace(arg1) }: "/usr/lib/dtrace/io.d", line 1: cannot find type: struct devstat*: Type information is in parent and unavailable Perhaps if we want to avoid confusion here, the right thing is to change the "invalid probe specifier" error message to something more meaningful? domagoj.stolfa_gmail.com: That's true -- and the error message in this particular case doesn't really seem like a great… | |||||||||
Not Done Inline ActionsThis is definitely something we can do better... I'll just say that the error handling in libdtrace is really quite hard to follow, there's some setjmp/longjmp and complicated interactions with the generated lexer and parser. So it may be an easy change, but also quite possibly is not an easy change. markj: This is definitely something we can do better... I'll just say that the error handling in… | |||||||||

It might be worth mentioning the /usr/lib/dtrace path, and that this can be used to resolve the error jhb was running into.
Infact, it might be worth putting the exact error message here, so that search results for that error lead to this man page.
