Rails¶

The Rails integration provides insights for your Ruby on Rails application stack.

To begin, navigate to the Integrations page:

To create a new integration, click on the Rails icon, then on the “Add Configuration” button:

inbound_rails_add

Give the integration a unique name.

inbound_rails_name

After saving, a configuration snippet is generated:

inbound_rails_config

Add the following to your Gemfile:

gem  'librato-rails'۪

Then run bundle install. Next, add the previously generated settings to config/librato.yml in your application. Custom prefixes are incompatible with the Rails integration. If you are using the integration, omit the prefix field from the configuration file. See the full configuration documentation for other available options.

Finally, commit and deploy your updated application. After a few minutes, you should begin seeing rails.* and rack.* metrics being reported. If you have any issues getting metrics to report, you may find the troubleshooting steps helpful. You may also want to take a look at the FAQ.

To verify the configuration, navigate to Spaces for access to the newly curated Rails dashboards:

Rails Overview inbound_rails_space

Rails SQL inbound_rails_sql

Rack inbound_rack_space

Once your data is showing up correctly you can start timing segments of your code in production or tracking events using custom instrumentation. Build custom spaces to get the exact views you need for what is most important for your application.
