Get notified of Rails errors instantly as they occur after deployment - and before users notice.
Similar errors are automatically grouped using Rollbar's fingerprinting technology to reduce noise, and all errors include detailed data to help you assess impact and assign priority.
Rollbar automatically collects all the data you need to replicate and debug an error, presented in ways optimized for debugging speed.
Get stack traces, request parameters, local variables, affected users and IP addresses, browsers and OSes, deployed code versions, and more.
RQL (Rollbar Query Language) allows you to perform data analysis and build custom reports on your error data, using a familiar SQL-like language.
You can use RQL to get answers to very specific questions, e.g. "How many users are getting by 404 errors right now, grouped by referring URLs?"
RQL is also accessible via API.
Using Rollbar I don’t have to spend time trying to reproduce errors on my own. It tells me what the steps are. Rollbar empowers your team to be able to sort through issues and turn things around quickly.
How to configure rollbar-gem to work with your Rails app
Run the following command from your Rails root:
rails generate rollbar POST_SERVER_ITEM_ACCESS_TOKEN
Be sure to replace
POST_SERVER_ITEM_ACCESS_TOKEN with your project's
post_server_item access token, which you can find in the Rollbar.com interface.
