google-cloud-error_reporting

Stackdriver Error Reporting counts, analyzes and aggregates errors raised in your running cloud services. A centralized error management interface displays the results with sorting and filtering capabilities. A dedicated view shows the error details: time chart, occurrences, affected user count, first and last seen dates and a cleaned exception stack trace. Opt-in to receive email and mobile alerts on new errors.

Quick Start

Install the gem directly:

$ gem install google-cloud-error_reporting

Or install through Bundler:

1. Add the google-cloud-error_reporting gem to your Gemfile:

gem "google-cloud-error_reporting"

1. Use Bundler to install the gem:

$ bundle install

Alternatively, check out the stackdriver gem that includes the google-cloud-error_reporting gem.

Enable Stackdriver Error Reporting API

The Stackdriver Error Reporting library needs the Stackdriver Error Reporting API to be enabled on your Google Cloud project. Make sure it's enabled if not already.

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 integration is enabled, it automatically reports exceptions captured from the application's Rack stack.

With Ruby on Rails

You can load the Railtie that comes with the library into your Ruby on Rails application by explicitly requiring it during the application startup:

# In config/application.rb
require "google/cloud/error_reporting/rails"

If you're using the stackdriver gem, it automatically loads the Railtie into your application when it starts.

With other Rack-based frameworks

Other Rack-based frameworks, such as Sinatra, can use the Rack Middleware provided by the library:

require "google/cloud/error_reporting"
use Google::Cloud::ErrorReporting::Middleware

Reporting errors manually

Manually reporting an error is as easy as calling the report method:

require "google/cloud/error_reporting"
begin
  fail "boom!"
rescue => exception
  Google::Cloud::ErrorReporting.report exception
end

Configuring the library

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

Running on Google Cloud Platform

The Stackdriver Error Reporting library for Ruby should work without you manually providing authentication credentials for instances running on Google Cloud Platform, as long as the Stackdriver Error Reporting API access scope is enabled on that instance.

App Engine

On Google App Engine, the Stackdriver Error Reporting API access scope is enabled by default, and the Stackdriver Error Reporting library for Ruby can be used without providing credentials or a project ID.

Container Engine

On Google Container Engine, you must explicitly add the cloud-platform OAuth scope when creating the cluster:

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

You may also do this through the Google Cloud Platform Console. Select Enabled in the Cloud Platform section of Create a container cluster.

Compute Engine

For Google Compute Engine instances, you must explicitly enable the cloud-platform access scope for each instance. When you create a new instance through the Google Cloud Platform Console, you can do this under Identity and API access: Use the Compute Engine default service account and select "Allow full access to all Cloud APIs" under Access scopes.

Running locally and elsewhere

To run the Stackdriver Error Reporting outside of Google Cloud Platform, you must supply your GCP project ID and appropriate service account credentials directly to the Stackdriver Error Reporting. This applies to running the library on your own workstation, on your datacenter's computers, or on the VM instances of another cloud provider. See the Authentication section for instructions on how to do so.

Authentication

The Instrumentation client and API use Service Account credentials to connect to Google Cloud services. When running on Google Cloud Platform environments, the credentials will be discovered automatically. When running on other environments the Service Account credentials can be specified by providing in several ways.

The best way to provide authentication information if you're using Ruby on Rails is through the Rails configuration interface:

# in config/environments/*.rb
Rails.application.configure do |config|
  # Shared parameters
  config.google_cloud.project_id = "your-project-id"
  config.google_cloud.keyfile = "/path/to/key.json"
  # Or Stackdriver Error Reporting specific parameters
  config.google_cloud.error_reporting.project_id = "your-project-id"
  config.google_cloud.error_reporting.keyfile = "/path/to/key.json"
end

Other Rack-based applications that are loading the Rack Middleware directly or using the manually reporting interface can leverage the configration interface:

require "google/cloud/error_reporting"
Google::Cloud.configure do |config|
  # Shared parameters
  config.project_id = "your-project-id"
  config.keyfile = "/path/to/key.json"
  # Or Stackdriver Error Reporting specific parameters
  config.error_reporting.project_id = "your-project-id"
  config.error_reporting.keyfile = "/path/to/key.json"
end

This library also supports the other authentication methods provided by the google-cloud-ruby suite. Instructions and configuration options are covered in the Authentication Guide.

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Stackdriver Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end

Supported Ruby Versions

This library is supported on Ruby 2.3+.

Google provides official support for Ruby versions that are actively supported by Ruby Core—that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. Currently, this means Ruby 2.3 and later. Older versions of Ruby may still work, but are unsupported and not recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.

Versioning

This library follows Semantic Versioning.

It is currently in major version zero (0.y.z), which means that anything may change at any time and the public API should not be considered stable.
