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.
  • quota_project - (String) The project ID for a project that can be used by client libraries for quota and billing purposes.
  • timeout - (Integer) Default timeout to use in requests.
  • endpoint - (String) Override of the endpoint host name, or nil to use the default endpoint.
  • 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.
  • on_error - (Proc) A Proc to be run when an error is encountered on a background thread, such as report or Middleware. The Proc must take the error object as the single argument. If ErrorReporting is being used to report errors using Google::Cloud::cofigure.on_error, then this on_error should be configured to report errors raised when reporting through ErrorReporting.

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.

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

  Google::Cloud.configure.error_reporting
end

.default_reporter(&block) ⇒ #report

Returns the global default reporter used by middleware and the report convenience method.

If the default reporter is already defined, returns it. Otherwise, if a block is given, it is called and the result is set as the default reporter. Otherwise, if no block is given, a reporter is constructed from the default project and credentials.

Returns:

.new(project_id: nil, credentials: nil, scope: nil, timeout: nil, endpoint: 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) (defaults to: nil)

    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) (defaults to: nil)

    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>) (defaults to: nil)

    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) (defaults to: nil)

    Default timeout to use in requests. Optional.

  • endpoint (String) (defaults to: nil)

    Override of the endpoint host name. Optional. If the param is nil, uses the default endpoint.

  • project (String) (defaults to: nil)

    Alias for the project_id argument. Deprecated.

  • keyfile (String) (defaults to: nil)

    Alias for the credentials argument. Deprecated.

.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) (defaults to: nil)

    An identifier for running service. Optional.

  • service_version (String) (defaults to: nil)

    A version identifier for running service.

Yields:

  • (error_event)
