I want to profile a particular slow admin action that we have, but it calls _redirect at the end, is there an in-built way of seeing this profile information, or will I have to manually create an event to listen to something like controller_front_send_response_after and output the information into a log file?

Incidentally, Mage::run calls Varien_Profiler::stop('mage'); seemingly as the last thing the application does. Surely this call actually does nothing because the block is already rendered at that point, or did I miss something?

This post might help you: http://forrst.com/posts/Log_Varien_Profiler_output_to_file-h97. It explains how you output the Varien_Profiler contents to a log.

With that you can create your own extension, create an observer that listens to controller_front_send_response_after (or any other event) and log the Profiler results in the observer.

  • This is essentially what I've done, with the exception I'm checking for a registry entry so that I only get output for the actions I want by registering that variable in the actions I wish to debug. I'll accept this answer if nobody comes up with a built in way of doing it (which I doubt they will). Commented Nov 1, 2013 at 11:50
  • I've actually looked for it before on Mage 1.7. wasn't in there yet :) Commented Nov 1, 2013 at 11:56
