truncating aggregation output only
Hello dtrace-discuss,
Sometimes I want to run a script for some time and every n second
output N top entries. trunc() isn''t suitable here as it also removed
keys/values. I want it ''coz over time if I use sum() entries which
are normally truncated can actually get to top over a time.
Maybe printa() extension, something like: printa(@b[10]) - to output
top 10?

sh DTrace provider available
As noted on my blog and at
http://www.opensolaris.org/os/community/dtrace/shells/ I''ve made
available a DTrace provider for the Bourne shell. Before anyone starts
yelling at me for not starting with another shell, read the blog I made
explaining why we started with shell (link on the community page
referenced above).
For /bin/sh, I''ve put up something akin to a chapter in

ddi_pathname
Hello,
I can see that there is an implementation/emulation of ddi_pathname in DTrace, but I''m a bit confused about the capabilities and invocation of this function. I would like to diplay the path to the block device from bdev_strategy and other io:genunix::start probes.
If someone is familiar with ddi_pathname, could you please provide an example invocation?
Thanks,
Michael

getting hex out of ints
I have a probe:
pid111::myfunc:entry
{
self->arg = arg0;
}
pid111::myfunc:return
/self->arg/
{
@[self->arg] = quantize();
}
works great, but i''d like arg0 to be printed in hex. I''ve tried numerous approaches to do this but i''ve hit a wall every time. I''ve tried:
1) self->arg = sprintf(arg0);
no, cuz dtrace has no sprintf
2) self->arg

How can I watch IO operations with dtrace on zfs?
I have been using iosoop script (see http://www.opensolaris.org/os/community/dtrace/scripts/) written by Brendan Gregg to look at the IO operations of my application. When I was running my test-program on a UFS filesystem I could see both read and write operations like:
UID PID D BLOCK SIZE COMM PATHNAME
203803 4436 R 6016592 16384 diskio <none>

Aggregation elements
Howdy,
Is there a method to get the number of elements in an aggregation? Are the
results stored in an aggregation guaranteed to be in any type of order?
Thanks for any insight,
- Ryan

Can I use printa() for printing multiple agg regations?
Hi Bryan,
> Does that sit well with everyone?
Seems fine to me.
Just revisiting one of Dragan''s points, though (sorry if I missed the
answer) - is there a reason for making this global (via a #pragma) rather
than, say, simply providing two functions which print in the different
orders? e.g. printa() for sort by sample, printak() for sort by key.
My reason for wanting to do both in

[PATCH RFC 0/8] xen/arm: initial cubieboard2 support.
See http://www.gossamer-threads.com/lists/xen/devel/297170 for some
information on how to get this going.
I''ve rebased and addressed the review comments.
As before several of the patches are not to be applied because they can
be done better using infrastructure from Julien''s "Allow Xen to boot
with a raw Device Tree" patch. They are included for completeness.

rsync failing with return code 13
Hi there,
I'm running rsync on an nslu2 (using nslu2-linux) and it keeps failing
with return code 13. The man page doesn't give a good description of
what this means ("Errors with program diagnostics") so could someone
give me a clue. as to what diagnostics rsync is running and reasons why
they might be failing? The only magic to note is the machine only has
32MB of ram so low

[PATCH 00/13] Fix errors found using Coverity static analyzer.
I ran the Coverity static analyzer[1] on libguestfs, and fixed many
errors as a result.
Coverity found some errors in gnulib, but it doesn't seem to be worth
following those up since the version of gnulib we are using is so old.
There are a couple more errors (possibly 1 false-positive) which I'm
going to send in a separate email.
BTW all the errors found by Coverity were in the daemon

Running dtrace sript for defined period of time?
Hello,
I''m building some simple monitoring tools to watch zfs storage servers.
Is this possible to run dtrace script for example 10 seconds? (Of course it is, I just trying to figure out how). Right know it has to be stopped by "CTRL-C"
I''m particulary interested in scripts like iscsiio.d, iscsiwho.d from

Full Ack. It''s quite difficult, though, to predict what DTrace features one will get when installing Solaris 10 (whatever release). There is nothing about the fine details of

total warning-removal for daemon/
The warnings in daemon were aggravating and risky
for development (too easy to miss new ones) so I spent some
time last week and today working on removing them.
The first patch gets us down to almost no warnings with
the original -Wall setting. That was by far the hardest part.
Once I'd done that, I enabled nearly all of gcc's warnings via
gnulib's warnings and manywarnings modules
