Rails 2 & Profiler

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.

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…

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

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 :slight_smile:
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…
