Sun Wins Top Tech Innovation Award
Carl Bialik from WSJ writes "Sun's DTrace trouble-shooting software won top prize in the Wall Street Journal's 2006 Technology Innovation Awards competition. It's the second time in three years that Sun took the top award. From the article, which also names a dozen other winners: 'Where most debugging takes place as software is being developed, DTrace analyzes problems with systems that are in production — running a company's database, say, or executing stock trades. It does this with a process called "dynamic tracing," which enables a developer or systems administrator to run diagnostic tests on a system without causing it to crash. Before DTrace, such tests often took days or weeks to reproduce the problem and identify the cause. With DTrace, performance problems can be tracked to their underlying causes in hours, even minutes.'"
DTrace has a degree of OS integration that makes it non-trivial to copy, linux's alternatives don't even come close even though a tool like this would be very useful in linux.
For the foreseeable future, if you want to have this type of debugging on your server then the server has to run Solaris. And if your server is bigger than a 4-way then it makes sense that it's a Sun server.
There is value in premium gear, and while it won't make Sun the next Dell, it can hopefully help improve their standing in their core market.

Sounds like they've put those HP founders to work, instead of just parading them around in t-shirts.

After all, it takes a considerable amount of insight to pick a code analyzer (admittedly one as brilliant as dtrace) as important and newsworthy. Good job, guys! It shows you can look deeply at a topic and understand what makes computer systems valuable. A lesser effort would award something from Microsoft, Google or Apple, whose products are great, but lack the sophistication of many Sun innovations.

strace is more like Solaris's truss, except truss is quite a lot better. IMO dtrace is for more serious debugging, tools like truss & strace are quick and dirty tools for easy to solve problems where just knowing the system call and their return values is enough to diagnose the issue.
Several people have mentioned strace, but I have yet to see anyone mention oprofile. I haven't used dtrace before, but oprofile allows you to see where an application is spending it's time transparently, with negligible performance hit, and without restarting the application.
oprofile has been around since late 2002 it seems, so it's not particularly new either. How does dtrace compare to oprofile?

I used to work for Sun and DTrace is da bomb to put it mildly. It has ZERO impact on real-time execution and can even see into the OS (if you use Solaris). I've built many a real-time system over the years and having this tool would have saved me countless hours of debugger time and logic analyzer time. The one down side to Dtrace is that it does so much it is hard to Master. There is a week long course Sun reccomends before you really can get the most for your efforts. I think it deserves a place on the Innovation shelf right beside the T1 chipset. And there are plans to port a version to Linux, but it may not be free. It also probably won't be able to see as deep into the OS layers as it does with Solaris but that will come in due time. Sun's license isn't 100% compatiable with the Linux GPL either so that could be another issue
