Just a quick note to tell people that I/we have been running a blog/group site on performance visualization which you can see by clicking here . If you are not already a member you should see a link on the right side that says "Apply for group membership". Just click on this and you could become a happy member.

Hi, just a note to tell you that I will be presenting the paper "Seeing it all at once with Barry" in Toronto on April 16. This is the visualization paper which Neil and I wrote and presented at CMG in San Diego. I look forward to redoing it with some new visuals and hopefully will report back in a timely manner. Till later.

What happened in San Diego. Well, a lot apart from the fact that I was fortunate enough to have two distinguished speakers speak for the network track, namely Peter Sevcik from Netforecast, a world renowned consultant that knows his stuff and whose opinions are often against the current but proven to be correct after. His pet peeve these days is the application performance index or APDEX (see Apdex Alliance ). My good friend Neil Gunther ( Neil's blog ) and I presented a new visualization for the Apdex index which we believe has a lot of potential. The other distinguished speaker is Raj Jain , a well known academic whose performance book The Art of Computer Systems Performance Analysis: Techniques for Experimental Design, Measurement, Simulation, and Modeling (Hardcover) has been the bible for many old timer performance analyst. Raj current interest is in participating in the design of the Internet 3.0 (I don't know where I was but I don't recall Internet 2.0 but heck,...

Yeah, exactly what I asked the first time I started thinking about it. But then I met my buddy Neil at CMG (Computer Measurement Group) in Reno (brrr, was it cold there) and we started talking about hot topics and performance visualization came up. Actually, I don't recall if this happened before or after we had a few beers. This is not that important because most really good ideas came after a few beers. So, back to the topic at hand. Visualization is not a new concept. It has been used in several fields. Here is a list of web site with various applications of visualization: digg labs Parallel coordinates Treemaps for space-constrained visualization of hierarchies Edward Tufte sparklines John Tukey Gallery of Data Visualization Earth Simulator Center Here is a technical article on visualization as it applies to computer and network performance.
