What is it
Cloud Logging is a fully managed log management product, supporting both real-time operations and long-term analytics use cases.
When to use it
Use Cloud Logging to investigate issues and get insight into the operation of your backend service, by analyzing the application logs and request logs.
If you have used the Cloud Runner SDK, your service should already have logging and tracing configured. This enables you to, for example, filter on all logs for a specific request trace.
