Setting Up Stackdriver Error Reporting for Ruby

You can send error reports to Stackdriver Error Reporting from Ruby applications by using the Stackdriver Error Reporting library for Ruby.

Stackdriver Error Reporting is integrated with some products, such as App Engine. Stackdriver Error Reporting displays the errors that are logged to Stackdriver Logging by applications running on those products. See Running on Google Cloud Platform for more information.

Before you begin

  1. Sign in to your Google Account.

    If you don't already have one, sign up for a new account.

  2. Select or create a GCP project.

    Go to the Manage resources page

  3. Make sure that billing is enabled for your project.

    Learn how to enable billing

  4. Enable the Stackdriver Error Reporting API.

    Enable the API

  5. Install Ruby 2.2+ or greater.

Installing the client library

Stackdriver Error Reporting library for Ruby lets you monitor and view errors reported by Ruby applications running nearly anywhere.

  1. Add the Stackdriver gem to your Gemfile:

    gem "stackdriver"
  2. Use Bundler to install the gem:

    bundle install

Enabling the library

If you're using Ruby on Rails, Bundler automatically loads the library into your application when it starts.

Other Rack-based applications can use the Rack Middleware provided by the library:

require "google/cloud/error_reporting"

use Google::Cloud::ErrorReporting::Middleware

For more information on installation, see the documentation for the Stackdriver Error Reporting library for Ruby. You can also report issues using the issue tracker.

Configuring the client library

You can customize the behavior of the Stackdriver Error Reporting library for Ruby. See the library's configuration for a list of possible configuration options.

Reporting errors

Reporting errors in Rack-based frameworks

The Stackdriver Error Reporting library for Ruby makes it easy to integrate Stackdriver Error Reporting into popular Rack-based Ruby web frameworks such as Ruby on Rails and Sinatra. When the library is enabled, it automatically reports exceptions captured from the application's Rack stack.

Reporting errors manually

You can manually report an error by calling the report method, as seen in the following example:

require "google/cloud/error_reporting"

begin
  fail "Raise an exception for Error Reporting."
rescue => exception
  Google::Cloud::ErrorReporting.report exception
end

Running on Google Cloud Platform

Using the Stackdriver Error Reporting library for Ruby requires the Cloud IAM Error Reporting Writer role. Most Google Cloud Platform computing platforms provide this role by default.

App Engine flexible environment

Google App Engine grants the Error Reporting Writer role by default.

The Stackdriver Error Reporting library for Ruby can be used without needing to explicitly provide credentials.

Stackdriver Error Reporting is automatically enabled for App Engine environment applications. No additional setup is required.

Kubernetes Engine

On Google Kubernetes Engine, you must add the cloud-platform access scope when creating the cluster, as the following example command shows:

gcloud container clusters create example-cluster-name --scopes https://www.googleapis.com/auth/cloud-platform

Compute Engine

When using Google Compute Engine VM instances, add the cloud-platform access scope to each instance. When creating a new instance through the Google Cloud Platform Console, you can do this in the Identity and API access section of the Create Instance panel. Use the Compute Engine default service account or another service account of your choice, and select Allow full access to all Cloud APIs in the Identity and API access section. Whichever service account you select, ensure that it has been granted the Error Reporting Writer role in the IAM & admin section of the GCP Console.

Running locally and elsewhere

To use the Stackdriver Error Reporting library for Ruby outside of Google Cloud Platform, you must supply your GCP project ID and appropriate service account credentials directly to the Stackdriver Error Reporting library for Ruby. This applies to running the library on your own workstation, on your data center's computers, or on the VM instances of another cloud provider. For more information see Obtaining and providing service account credentials manually.

Using Ruby on Rails configuration interface

To use the Stackdriver Error Reporting library for Ruby with the Ruby on Rails framework, provide the parameters through the Ruby on Rails configuration interface:

# Add this to config/environments/*.rb
Rails.application.configure do |config|
  # Stackdriver Error Reporting specific parameters
  config.google_cloud.error_reporting.project_id = "YOUR-PROJECT-ID"
  config.google_cloud.error_reporting.keyfile    = "/path/to/service-account.json"
end

You can also set shared configuration for all Stackdriver gems using the following:

# Add this to config/environments/*.rb
Rails.application.configure do |config|
  # Stackdriver Shared parameters
  config.google_cloud.project_id = "YOUR-PROJECT-ID"
  config.google_cloud.keyfile    = "/path/to/service-account.json"
end

Error Reporting is enabled by default when Rails is running in production mode. To enable Error Reporting in development mode, add the following:

# Add this to config/environments/development.rb
Rails.application.configure do |config|
  config.google_cloud.use_error_reporting = true
end

Using instrumentation configuration interface

To use the Stackdriver Error Reporting library for Ruby in other Rack-based applications, provide the parameters through the configuration interface:

require "google/cloud/error_reporting"

Google::Cloud.configure do |config|
  # Stackdriver Error Reporting specific parameters
  config.error_reporting.project_id = "YOUR-PROJECT-ID"
  config.error_reporting.keyfile    = "/path/to/service-account.json"
end

You can also set shared configuration for all Stackdriver gems using the following:

require "stackdriver"

Google::Cloud.configure do |config|
  # Stackdriver Shared parameters
  config.project_id = "YOUR-PROJECT-ID"
  config.keyfile    = "/path/to/service-account.json"
end

Viewing error reports

After deployment, you can view error reports in the GCP Console Error Reporting dashboard.

Go to the Error Reporting dashboard
