Retrieve Heroku Logs for Specific Remote

Question

I have a Rails 4 app that I push to Heroku from Git. I have a staging remote and a production remote on Heroku. When I run:

$ heroku logs

I get the staging logs. How can I get the production logs?

$ git remote -v
origin some/github/path (fetch)
origin some/github/path (push)
staging git@heroku.com:some-heroku-app.git (fetch)
staging git@heroku.com:some-heroku-app.git (push)
production git@heroku.com:some-other-heroku-app.git (fetch)
production git@heroku.com:some-other-heroku-app.git (push)

Attempts include:

$ heroku logs -s staging

Answer 1

Replace -s with -r. heroku logs -r staging (or production or whatever).

Answer 2

Use the Heroku app name

heroku logs --app my-production-app
