Cloud Logging API - Module Google::Cloud::Logging (v2.6.0)

Reference documentation and code samples for the Cloud Logging API module Google::Cloud::Logging.

Stackdriver Logging

The Stackdriver Logging service collects and stores logs from applications and services on the Google Cloud Platform, giving you fine-grained, programmatic control over your projects' logs. You can use the Stackdriver Logging API to:

• Read and filter log entries
• Export your log entries to Cloud Storage, BigQuery, or Cloud Pub/Sub
• Create logs-based metrics for use in Cloud Monitoring
• Write log entries

For general information about Stackdriver Logging, read Stackdriver Logging Documentation .

See Stackdriver Logging Overview .

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
• 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.
• 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.
• set_default_logger_on_rails_init - (Boolean) Whether Google Cloud Logging Logger should be allowed to start background threads and open gRPC connections during Rails initialization. This should only be used with a non-forking web server. Web servers such as Puma and Unicorn should not set this, and instead set the Rails logger to a Google Cloud Logging Logger object on the worker process by calling <a href="Google-Cloud-Logging-Railtie#Google__Cloud__Logging__Railtie_set_default_logger_class" title="Google::Cloud::Logging::Railtie.set_default_logger (method)">Railtie.set_default_logger at the appropriate time, such as a post-fork hook.
• on_error - (Proc) A Proc to be run when an error is encountered on a background thread. The Proc must take the error object as the single argument. (See AsyncWriter#on_error .)

See the Configuration Guide for full configuration parameters.
