[dtrace-discuss] Auto-Generating and custom header files for probes
Hi all,
I am trying to understand how to:
1. Auto generate the probe header from a probes.d file: Isn?t it as
simple as ?dtrace -h simple_probes.d'', where ?imple_probes.d:
<code>
provider simple {
probe saw__word(int);
probe saw__line(int);
};
</code>
however, when i do the above, I get: ''dtrace: -h requires one or more
scripts or enabling options?
(I am following:
http://blogs.sun.com/barts/entry/putting_user_defined_dtrace_probe)
2. How to generate custom probe header macros and how does it work?
This page here:
http://www.solarisinternals.com/wiki/index.php/DTrace_Topics_USDT#USDT_Macros
hints at it, but is rather incomplete.
Thank You!
Regards,
Amit

You''re missing a ''-s'' option. I think this might be a better reference: http://blogs.sun.com/ahl/entry/user_land_tracing_gets_better Adam On Mar 10, 2009, at 11:36 PM, Amit Saha wrote:> Hi all, > > I am trying to understand how to: > > 1.

(Earlier, I was using it together with h, i.e. -hs ) Thank You very much!

However, I cannot see it being used anywhere there. Am I missing something? (Sorry if I am). Thank You very much.

PROVIDER and PROBE were meant to be in italics to indicate that they were placeholders for the actual provider and probe names, but the formatting doesn''t make that completely clear. Sorry about that. The USDT documentation in the DTrace guide definitely needs some work which would be a great and much appreciate project if anyone''s interested in taking a crack at it.
