Sentry on Heroku

Sentry is a realtime event logging and aggregation platform. At its core it specializes in monitoring errors and extracting all the information needed to do a proper post-mortem without any of the hassle of the standard user feedback loop.

Basic setup

Follow the steps below to get Sentry up and running on Heroku:

1. Create a new Heroku application. Replace "APP_NAME" with your application's name:

   heroku apps:create --stack cedar APP_NAME
   

2. Add database to the application:

   heroku addons:add heroku-postgresql:dev
   

4. Set the heroku app name (and custom domain if needed)

   heroku config:add HEROKU_APP_NAME='my_app_name' heroku config:add CUSTOM_DOMAIN='.customdomain.com'

3. Set Sentry's shared secret for global administration privileges:

   heroku config:add SENTRY_KEY='0123456789abcde'
   

   You may use the following Python code to generate a good unique key for the above:

   >>> import base64
   >>> import os
   >>> base64.b64encode(os.urandom(40))
   'nIumxPtjDuHunpX2D+LP27l8WX967DgjBRiSLz/XrfAp491bu3pnzw=='
   

4. Deploy Sentry to Heroku:

   git push heroku master
   

5. Run Sentry's database migrations:

   heroku run "sentry --config=sentry.conf.py upgrade"
   

6. Create a user account for yourself:

   heroku run "sentry --config=sentry.conf.py createsuperuser"
   

7. Restart the app so everything is up-to-date:

   heroku restart
   

That's it! Open your newly created sentry server: heroku open

Email notifications

Follow the steps below, if you want to enable Sentry's email notifications:

1. Add SendGrid add-on to your Heroku application:

   heroku addons:add sendgrid
   

2. Set the reply-to email address for outgoing mail:

   heroku config:add SERVER_EMAIL=sentry@example.com
   

3. Set the email addresses that should be notified:

   heroku config:add ADMINS=john.matrix@example.com,jack.daniels@example.com
