Re: [dtrace-discuss] Introducing DTrace to a newbie audience
That was a weird typo. Appreciate the catch. -- This message posted from opensolaris.org ___ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
Re: [dtrace-discuss] Introducing DTrace to a newbie audience
# dtrace -qn 'syscall:::exec-success { trace (execname); }'
^
The exec-success probe is managed by the proc provider, not
the syscall provider. So the probe designation should be;
proc:::exec-success (or just 'exec-success').
(for the newbies).
Thanks,

Xsun, Xorg, and apache httpd are all daemons with USDT probes in. For Xsun/Xorg, the details & diffs are posted at: http://people.freedesktop.org/~alanc/dtrace/ For apache, google of "apache httpd dtrace" finds a number of hits, this one looks most relevant: http://prefetch.net/projects/apache_modtrace/index.html -- -Alan Coopersmith- alan.coopersm...@sun.com Sun Microsystems, Inc. - X Window System Engineering ___ dtrace-discuss mailing list dtrace-discuss@opensolaris.org

[dtrace-discuss] DTrace in daemon code
All, we're considering instrumenting the daemon we're developing for our project with SDT probes, and were a little surprised that a few cursory(sp?) searches didn't reveal any examples for this - does that mean a) we didn't search enough b) we're treading where no man has gone before c) there's some inherent issues with this?
