+# Open Dashboard For Specific Add-On
+
+The number of times I've needed to check the papertrail logs for my
+Heroku-hosted Rails app is a lot. I open a browser tab, go through several
+layers of navigation to get to my app's dashboard, and then click the
+papertrail link under _Add-ons_.
+
+There is a much quicker way using the Heroku CLI.
+
+```bash
+$ heroku addons:open papertrail -a my-app-name
+Opening https://addons-sso.heroku.com/apps/abc123/addons/efg456...
+```
+
+It sends you to an add-ons SSO link in the browser which authenticates you and
+drops you into the dashboard for that specific add-on. You just need to specify
+the add-on name and the app name.
