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 is to provide an API that is comfortable to Rubyists. Your authentication credentials are detected automatically in Google Cloud Platform environments such as Google Compute Engine, Google App Engine and Google Kubernetes Engine. In other environments you can configure authentication easily, either directly in your code or via environment variables. Read more about the options for connecting 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

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| ... } ⇒ Google::Cloud::Config

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

The following Stackdriver ErrorReporting configuration parameters are supported:

  • project_id - (String) Google Cloud Platform project identifier for the Stackdriver Error Reporting service you are connecting to. (The parameter project is considered deprecated, but may also be used.)
  • credentials - (String, Hash, Google::Auth::Credentials) The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials) (The parameter keyfile is considered deprecated, but may also be used.)
  • scope - (String, Array) The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access.
  • timeout - (Integer) Default timeout to use in requests.
  • client_config - (Hash) A hash of values to override the default behavior of the API client.
  • service_name - (String) Name for the application.
  • service_version - (String) Version identifier for the application.
  • ignore_classes - (Array) Array of exception types that should not be reported.

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"
  config.credentials = "/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:

  • (Google::Cloud::Config) —

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

  Google::Cloud.configure.error_reporting
end

.new(project_id: nil, credentials: nil, scope: nil, timeout: nil, client_config: nil, project: nil, keyfile: 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_id (String) —

    Google Cloud Platform project identifier for the Stackdriver Error Reporting service you are connecting to. If not present, the default project for the credentials is used.

  • credentials (String, Hash, Google::Auth::Credentials) —

    The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials)

  • 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.

  • project (String) —

    Alias for the project_id argument. Deprecated.

  • keyfile (String) —

    Alias for the credentials argument. Deprecated.

Returns:

Raises:

  • (ArgumentError)

.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)
