Hi Angelo!

> Hello SeongHwa,

> I'm looking forward to presenting the DTrace hands on lab at OSCON - Monday, July 19, 8:30AM in D139/140. We have a very packed lab plan for you. In fact we have over 6 hrs of content jammed into 3:30 hrs. The idea was to provide something for everyone and allow the attendees to pick and choose the areas they want to work on.

> To make the lab more effective and emphasize on the right areas I would love to understand a little about you and your interest.
> I would really appreciate if you could take a few minutes to answer a few questions for me. Please post all responses to this Google groups page: http://groups.google.com/group/DTraceHOL?hl=en
> (this will require you have a Gmail account.)

Hi Angelo,

1. Other - System Engineer, but I used to be an Architect in the past.

2. Solaris - Yes; Linuxes - Most; Other Unixes - Mac OS X and other
*BSD*, and a host of old and obscure Unix flavors; Other - None that
I've worked with seriously in the past 5-10 years.

3. Yes, Yes, but mostly just example scripts.

4. C, Java, PHP, PERL.

5. Yes, Yes.

6. Mostly just what you plan on presenting, but it would be useful to
have some insight into how to use Dtrace to do monitoring of a
production system over time. That is, something that would replace
and expand upon traditional UNIX system accounting (for both Solaris
and Mac OS X).

See you in Portland!

Cheers!
Greg

> 5. Are you familiar with the LAMP stack? Do you use it?

I am familiar with it, and we do have some systems using it.

I am interested in using DTrace to track down performance bottlenecks
in Java-applications running on CMT processors.
