So the new profiler in Rails 2.0 looks great - except I can’t figure out how to use the damn thing with my application. I have two unique things that might be preventing me from enjoying the profiler - My app requires a login - My app request a subdomain be present to function Has anyone worked with profiler that can help me out here, or perhaps link me to a good write up on the subject? I googled around, searched technorati, etc - but nothing was there to be found. Documentation on this effort seems to be non-existent, and cracking the source isn’t helping me much either. Someone point me in the right direction. * * * ## seth at subimage interactive ## [http://sublog.subimage.com](http://sublog.subimage.com) ## Cashboard - Estimates, invoices, and time tracking software - for free!

To follow up, with a little help from #rubyonrails I figured out that you need to use integration test commands to get it running. Armed with that information, I’ve gotten a little further, but not much. I’m now getting some error that looks like s UTF-8 problem… [http://pastie.caboo.se/pastes/131238](http://pastie.caboo.se/pastes/131238) Help?

The new request profiler is young and experimental still; thanks for giving it a spin. Write an integration script much like you would for integration tests. Example: test/performance/authorize\_user\_and\_redirect\_back.rb host! ‘[foo.com](http://foo.com)’ get ‘/admin/posts/1’ follow\_redirect! raise unless path == ‘/login’ post ‘/login’, :username =\> ‘john’, :password =\> ‘doe’ follow\_redirect! raise unless path == ‘/admin/posts/1’ then run ./script/performance/request test/performance/authorize\_user\_and\_redirect\_back.rb and check out the generated html call graph. The call graph is hard to interpret at first. We’ll have to work with the ruby-prof guys to improve that. Best, jeremy ---

Thanks Jeremy for the help here and on IRC 🙂 Anything that can be done to improve the readability of the graph would be really nice. As it is, I feel like I’m looking at a puzzle that I don’t yet know how to figure out… On Dec 21, 2007 3:24 PM, Jeremy K.
