Cloud Logging API - Class Google::Cloud::Logging::Entry (v2.5.0)

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

Entry

An individual entry in a log.

Each log entry is composed of metadata and a payload. The metadata includes standard information used by Stackdriver Logging, such as when the entry was created and where it came from. The payload is the event record. Traditionally this is a message string, but in Stackdriver Logging it can also be a JSON or protocol buffer object. A single log can have entries with different payload types.

A log is a named collection of entries. Logs can be produced by Google Cloud Platform services, by third-party services, or by your applications. For example, the log compute.googleapis.com/activity_log is produced by Google Compute Engine. Logs are simply referenced by name in google-cloud. There is no Log type in google-cloud or Log resource in the Stackdriver Logging API.

Examples

require "google/cloud/logging"

logging.write_entries entry
