Ray has traditionally used unstructured logs due to Python's built-in logging library, resulting in slow development time and integration challenges with existing log viewing solutions. To address these issues, Anyscale has introduced structured logging, which standardizes log entries in a JSON format, making them easier to handle and analyze. This enables seamless integration with tools like the ELK Stack or Datadog, and facilitates better indexing and querying of logs. Additionally, the new Log Viewer provides enhanced functionality, including automatically enhanced structured logging, centralized log viewing, scalability, filtering, and context, making application monitoring and debugging more efficient and effective.
