Rack-mini-profiler showing up in production for admins?

(Jaime Iniesta) #1

Hi, I just installed Discourse following the instructions at discourse/INSTALL-digital-ocean.md at master · discourse/discourse · GitHub and found that rack-mini-profiler is activated:

Is this intended? How can I disable it?

Thanks! And congrats, it’s been super easy to install Discourse following this guide.

Slow performance due to per query latency connecting to database?

That’s odd!


Did you followed the guide as is? (did you access the rails console?)

(Jaime Iniesta) #3

Yes, I followed the guide as is, and I didn’t access the rails console, should I?

(Jaime Iniesta) #4

Ah, one I thing I just noticed, the profiler only appears when I’m logged in as an admin.

(Arpit Jalan) #5

No, I was just clarifying.

This is the odd case, I’ll check.

(Jeff Atwood) #6

This is correct, if you are the admin, you will see profiler timings.

(Jaime Iniesta) #7

Ah, alright, thanks for the clarification.

(Kane York) #8

Yeah, this is completely intended @techAPJ - it’s a very good idea to be keeping an eye out for performance regressions, and MiniProfiler shoves it in your face! :stuck_out_tongue:

If you do not want it add


To your env: section in your container definition and run:

./launcher rebuild app

Is it removed from newer versions? I’m using 1.1.0.beta7 and I see it is still there in defaults.conf.

(Jeff Atwood) #11

Is is there for developer admins only, e.g. the accounts that installed Discourse. Is that correct @sam? I am very hazy on what makes a ‘developer’ admin account vs. regular admin.

There is a setting in app.yml

(Sam Saffron) #13
def is_developer?
    @user &&
    is_admin? &&
    (Rails.env.development? ||
        Rails.configuration.respond_to?(:developer_emails) &&
  1. Is admin
  2. Running in DEV, OR, In the DISCOURSE_DEVELOPER_EMAILS list which is set via the ENV var or in discourse.conf

(axil) #14

That must be it. After installing, I removed my email from app.yml so that I could put it under version control and ran rebuild again. So if I wanted mini-profiler to be back, all I have to do is to rebuild the container with the DISCOURSE_DEVELOPER_EMAILS env variable. Thanks.

I just installed and setup Discourse on a VPS at Linode and read the FAQ and Admin Read Me. Maybe I overlooked it but the profiler isn’t mentioned and might cause confusion for non-developer types who install Discourse.

The problem with the profiler stats is that it interferes with the editor when creating a topic, at least it just did for me when you get down to a smaller window size, even 1280px wide.

This screenshot shows the profiler overlaying editor field at 1280px wide. I think it would be better to have it sit over to the right instead of the left to avoid covering up the editor toolbar and text field.

I would simply use Alt+P to toggle the profiler stats off whilst they are in the way…
… back on after.

(Brian Boatright) #17

That’s great, didn’t know it had a shortcut.

Can we get the shortcut and the profiler mentioned in the Admin Read Me?

(Sam Saffron) #18

If you remove yourself from the developer list in the container config, mini profiler will go away.
