You can DTrace Perl apps, Python apps, PHP apps and more. You can DTrace databases. You can even DTrace JavaScript in Mozilla. So you can have all the information -- what user clicked, what webserver received, how SQL query was generated, how much time all those calls took, what parameters and return values were passed, what was served from cache... and so on. DTrace is great.
