dtrace discuss - Jan 2006 - implementing timer-based scripts with dtrace_user+dtrace_proc

Hi,

I''ve got a scenario where I''d like to have users
run DTrace, but without the dtrace_kernel privilege.
As documented, I can write probes using the profile
provider with these privileges:

% ppriv $$
24864:    -csh
flags = <none>
    E: basic,dtrace_proc,dtrace_user
    I: basic,dtrace_proc,dtrace_user
    P: basic,dtrace_proc,dtrace_user
    L: all

% dtrace -n ''tick-1{}''
dtrace: description ''tick-1'' matched 1 probe

But then I get nothing, unless I run a busy loop
program. Now I understand this is behaving as
documented (probe only fires if a process I have
permissions to is running on CPU), but not as I had
expected/hoped.

Is there any way of doing basic interval-based
profiling without dtrace_kernel? If not, anything
coming?

Jim
