Overview

ErrorReporting

Stackdriver Error Reporting counts, analyzes and aggregates the crashes in your running cloud services. The Stackdriver Error Reporting Instrumentation client provides a simple way to report errors from your application.

For general information about Stackdriver Error Reporting, read Stackdriver Error Reporting Documentation.

The goal of google-cloud-ruby is to provide an API that is comfortable to Rubyists. Authentication is handled by the client. You can provide the project and credential information to connect to the Stackdriver Error Reporting service, or if you are running on Google Cloud Platform this configuration is taken care of for you. You can read more about the options for connecting in the Authentication Guide.

How to report errors

You can easily report exceptions from your applications to Stackdriver Error Reporting service:

require "google/cloud/error_reporting"

# Configure Stackdriver ErrorReporting instrumentation
Google::Cloud::ErrorReporting.configure do |config|
  config.project_id = "my-project"
  config.keyfile = "/path/to/keyfile.json"
end

# Insert a Rack Middleware to report unhanded exceptions
use Google::Cloud::ErrorReporting::Middleware

# Or explicitly submit exceptions
begin
  fail "Boom!"
rescue => exception
  Google::Cloud::ErrorReporting.report exception
end

See the Instrumentation Guide for more examples.

Class Method Details

.configure {|Google::Cloud.configure.error_reporting| ... } ⇒ Stackdriver::Core::Configuration

Configure the default Project client, allows the report public method to reuse these configured parameters.

See the Configuration Guide for full configuration parameters.

Examples:

# in app.rb
require "google/cloud/error_reporting"

Google::Cloud::ErrorReporting.configure do |config|
  config.project_id = "my-project-id"
  config.keyfile = "/path/to/keyfile.json"
  config.service_name = "my-service"
  config.service_version = "v8"
end

begin
  fail "boom"
rescue => exception
  # Report exception using configuration parameters provided above
  Google::Cloud::ErrorReporting.report exception
end

Yields:

Returns:

  • (Stackdriver::Core::Configuration) —

    The configuration object the Google::Cloud::ErrorReporting module uses.

def self.configure
  yield Google::Cloud.configure.error_reporting if block_given?

  Google::Cloud.configure.error_reporting
end

.new(project: nil, keyfile: nil, scope: nil, timeout: nil, client_config: nil) ⇒ Google::Cloud::ErrorReporting::Project

Creates a new object for connecting to the Stackdriver Error Reporting service. Each call creates a new connection.

For more information on connecting to Google Cloud see the Authentication Guide.

Examples:

require "google/cloud/error_reporting"

error_reporting = Google::Cloud::ErrorReporting.new
# ...

Parameters:

  • project (String) —

    Project identifier for the Stackdriver Error Reporting service.

  • keyfile (String, Hash) —

    Keyfile downloaded from Google Cloud. If file path the file must be readable.

  • scope (String, Array<String>) —

    The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

    The default scope is:

    • https://www.googleapis.com/auth/cloud-platform
  • timeout (Integer) —

    Default timeout to use in requests. Optional.

  • client_config (Hash) —

    A hash of values to override the default behavior of the API client. Optional.

.report(exception, service_name: nil, service_version: nil) {|error_event| ... } ⇒ Object

Provides an easy-to-use interface to Report a Ruby exception object to Stackdriver ErrorReporting service. This method helps users to transform the Ruby exception into an Stackdriver ErrorReporting ErrorEvent gRPC structure, so users don't need to. This should be the prefered method to use when users wish to report captured exception in applications.

This public method creates a default Stackdriver ErrorReporting client and reuse that between calls. The default client is initialized with parameters defined in configure.

The error event can be customized before reporting. See the example below and ErrorEvent class for avaiable error event fields.

Examples:

Basic usage

# in app.rb
require "google/cloud/error_reporting"

begin
  fail "boom"
rescue => exception
  # Report exception using configuration parameters provided above
  Google::Cloud::ErrorReporting.report exception
end

The error event can be customized if needed

require "google/cloud/error_reporting"

begin
  fail "boom"
rescue => exception
  Google::Cloud::ErrorReporting.report exception do |error_event|
    error_event.user = "johndoh@example.com"
    error_event.http_status = "502"
  end
end

Parameters:

  • exception (Exception) —

    The captured Ruby Exception object

  • service_name (String) —

    An identifier for running service. Optional.

  • service_version (String) —

    A version identifier for running service.

Yields:

  • (error_event)
