How to read log/production.log from heroku if I run on puma web server

Question

I am running a puma web server on heroku and wants to get the .log file to check why a record is being rollbacked. I tried using heroku run bash and tried searching for config in puma.rb, but I still don't know how..

Any suggestions?

edit: I don't want heroku logs -t as it is just showing the logs from puma output. I need the output which when you tail -f log/development.log will show, more detail.

The reason I need it is because I am having a record that rollbacks and I don't know why. It only happens in production not in development, so I have to find out why.

If you really want to access the `production.log` file read this - http://stackoverflow.com/a/2672296/753705 — abhishek77in, Jul 26 '15 at 15:22
The production.log file is different from what I get from `heroku logs -t`. — Chris Yeung, Jul 28 '15 at 09:43
I believe in that case `heroku logs -t` should be your source of truth. — abhishek77in, Jul 28 '15 at 10:05

You can tail Heroku logs: heroku logs -t -a app-name https://devcenter.heroku.com/articles/logging

Also you can try out some addons on Heroku which will provide you with a in-browser view of your logs and allow some filtering on top of it - https://addons.heroku.com/?q=log
