Overview

Ruby Client for Stackdriver Logging API (GA)

Stackdriver Logging API: Writes log entries and manages your Stackdriver Logging configuration.

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable the Stackdriver Logging API.
  3. Setup Authentication.

Installation

$ gem install google-cloud-logging

Preview

LoggingServiceV2Client

require "google/cloud/logging"

logging_service_v2_client = Google::Cloud::Logging::Logging.new
formatted_log_name = Google::Cloud::Logging::V2::LoggingServiceV2Client.log_path(project_id, "test-" + Time.new.to_i.to_s)
resource = {}
labels = {}
entries = []
response = logging_service_v2_client.write_log_entries(entries, log_name: formatted_log_name, resource: resource, labels: labels)

Class Method Details

.configure {|Google::Cloud.configure.logging| ... } ⇒ Google::Cloud::Config

Configure the Google::Cloud::Logging::Middleware when used in a Rack-based application.

The following Stackdriver Logging configuration parameters are supported:

  • project_id - (String) Project identifier for the Stackdriver Logging 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.
  • log_name - (String) Name of the application log file. Default: "ruby_app_log"
  • log_name_map - (Hash) Map specific request routes to other log. Default: { "/_ah/health" => "ruby_health_check_log" }
  • monitored_resource.type (String) Resource type name. See full list. Self discovered on GCP.
  • monitored_resource.labels -(Hash) Resource labels. See full list. Self discovered on GCP.
  • labels - (Hash) User defined labels. A Hash of label names to string label values or callables/Proc which are functions of the Rack environment.

See the Configuration Guide for full configuration parameters.

Yields:

Returns:

  • (Google::Cloud::Config) —

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

  Google::Cloud.configure.logging
end

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

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

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

Examples:

require "google/cloud/logging"

logging = Google::Cloud::Logging.new

entries = logging.entries
entries.each do |e|
  puts "[#{e.timestamp}] #{e.log_name} #{e.payload.inspect}"
end

Parameters:

  • project_id (String) —

    Project identifier for the Stackdriver Logging 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/logging.admin
  • 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)
