What were you problems with SystemTap? I've only used it for some minor tracing but so far it actually worked quite nice. Except for the long compile time.

- qznc 13y agoI have no personal experience with either, but this dtrace guy does not like SystemTap: https://www.youtube.com/watch?v=TgmA48fILq8#1:13:00 https://www.youtube.com/watch?v=TgmA48fILq8#1:13:00 The whole presentation is a nice and impressive dtrace showcase.
- fafner 13y agoHe's quite unspecific. He just says "it's bad" and that Red Hat is getting its ass kicked by Sun. Not to mention that the talk is from 2007.
- qznc 13y agoWell, the final demo was a trace of a Python program (showing Python functions, not Python VM C functions) through the kernel (showing C Kernel functions) back (scheduling things) into Python. Can SystemTap do this (six years after this talk showcased it with dtrace)?
