Sentry provides a native add-on for Heroku. While this add-on is not required, it will allow you to maintain consolidated billing inside of Heroku, as well as enable easy configuration of your Sentry credentials.
Register the Add-on
To add Sentry to an existing Heroku app, head over to the Sentry Heroku add-on page.
Once done, you’ll be able to confirm that Sentry’s credentials are available via your config:
heroku config:get SENTRY_DSN
Install the SDK
Whether you’re using the add-on or not, you’ll still need to install the SDK per our standard platform-specific instructions.
Whether use the add-on or configure Sentry yourself, you’ll also likely want to grant quick access to your dyno metadata, which will allow Sentry to automatically pick up the git version of your application.
To do this, enable the
heroku labs:enable runtime-dyno-metadata -a <app name>
This exposes the
HEROKU_SLUG_COMMIT environment variable, which most Sentry SDKs will automatically detect and use for configuration.
Next you’ll want to add your repository and setup a deploy hook.
Start by connecting your repository to your Sentry organization so that we can automatically retrieve your commit data.
Enable the Heroku integration in your Sentry Project Settings.
In the Heroku Plugin Configuration, specify which repository and deploy environment to be associated with your Sentry project.
Navigate to your Project’s Release Tracking settings and copy the deploy hook command to your Heroku config.
You’ll start getting rich commit information and deploy emails with each new release, as well as tracking of which release issues were seen within.
