Performance reports by mail in production


in development mode you can turn auto_explain_threshold_in_seconds on
and see when a query is slow in the command prompt. Is there a gem that
can send me slow queries and slow loading pages in production mode? That
would make monitoring performance a lot easier. Thanks.

There are (paid) services like & newrelic that do this.

This is probably quite easy to implement in rails 3 using the ActiveSupport::Notifications stuff.
