Hi All, I don''t know if this is the appropriate list, but I would like to see a repository or contributor''s directory of dtrace scripts. I have been teaching dtrace in classes for over a year now, and have scripts that I have collected from various places, as well as scripts that I have written for classes. It would be nice to be able to find scripts that others have written, as well as scripts I have written, all in one place. I don''t think this needs to wait for source code license issues to be worked out. The /usr/demo/dtrace directory is a nice start. Possibly a /usr/demo/dtrace/contrib directory? As long as I''m at it, how about a /usr/demo/mdb/contrib directory with community contributed dcmds and walkers? max _______________________________________________ DTrace mailing list DTrace@opensolaris.org https://www.opensolaris.org/mailman/listinfo/dtrace
can you find a place to host what you have and others have for this list? i can find space on a web account i have, but that will only be for this list, sorry i know the server and pipeline wont survive the slashdotting it will see when opensolaris goes public or if it is made public. after we have it combined, we can maybe get sun.com to take over and make some web space availble for them all. james On Tue, 21 Dec 2004 09:33:40 -0800 (PST), Max Bruning <max@bruningsystems.com> wrote:> > Hi All, > > I don''t know if this is the appropriate list, but I would like to see a > repository or contributor''s directory of dtrace scripts.

Hosting is not an issue. I can do hosting if needed. Rather, I would like this to be in one easy to find place. Preferably a sun site or even better, with the system (/usr/demo/dtrace/contrib). Perhaps sunfreeware.com (is Steven Christensen on this mail list)??? I find it easiest to learn (and teach) dtrace by looking at and hacking existing scripts. When I need a detail, I can look it up in the 400+ page dtrace guide. max> On Tue, 21 Dec 2004, James Dickens wrote: > >> can you find a place to host what you have and others have for this >> list? i can find space on a web account i have, but that will only be >> for this list, sorry i know the server and pipeline wont survive the >> slashdotting it will see when opensolaris goes public or if it is >> made public. > > We can provide space (of course on a s10 box ;-) and nice fat pipes to the > Internet for Dtrace scripts or other goodies.

Bigadmin would be my preferred option. Maybe a dtrace collection?

Hi.
I would like to use mdb dcmds/walkers within dtrace scripts.
I filed an RFE for this a while back. Basically, what I would like to do
is something like:
foo:entry
/blah blah/
{
mdb_cmd("%x::print struct foo", bar); /* bar could be an arg, or
other
variable */
mdb_cmd("::threadlist -v");
mdb_cmd("%x::walk crud | ::mydcmd"); /* pipe output of a walker to
my
dcmd */
}
Perhaps dtrace using mdb''s dmods...
Also, there is a way to do almost what I want using kmdb
via the breakpoint action, if I could somehow pass a string
with commands to breakpoint().
Something like
foo:entry
{
breakpoint("kmdb commands");
}
Speaking of kmdb (and mdb for that matter), does anyone know how to specify
multiple kmdb/mdb commands when you hit a break/watch point?
I sometimes want to do something like:
foo::bp "<i0::print struct arg0 :c" /* print first arg and
continue from
debugger */
I can specify multiple commands with separate breakpoints, but it
is not the desired behaviour.
thanks,
max
