systemtap and ltt are the only full-scale tracing tools which target
sysadmins and applciation developers of which I am aware..
In the bit of text which you snipped I was agreeing with this...Agree. What would be the criteria that justifies having static probe vs a dynamic one?
Look, if Karim and Frank (who I assume is a systemtap developer) think that
we need static tracepoints then I have no reason to disagree with them. What I would propose is that:
a) Those tracepoints be integrated one at a time on well-understood
grounds of necessity. Tracepoints _should_ be added dynamically. But
if there are instances where that's not working and cannot be made to
work then OK, in we go.
