How can Envoy log specific HTTP request methods?

The correct answer is through access log settings in its configuration. Envoy provides a robust logging mechanism that allows users to configure access logs effectively. By utilizing access log settings, you can customize which specific HTTP request methods are logged, tailoring the output according to your application's monitoring and troubleshooting needs.

This configuration can include various details such as request path, status codes, response times, and specifically, the HTTP methods like GET, POST, PUT, DELETE, etc. The flexibility provided by Envoy's logging configuration is essential for developers and operators who want to gain insights into traffic patterns and diagnose issues related to specific request types.

In contrast, enabling default logging features only would not give the same level of detail or customization, as it typically logs all requests without filter options. Establishing a separate logging service is unnecessary because Envoy's built-in capabilities sufficiently handle logging. Direct integration with application code to manage logs presents more complexity and might not utilize Envoy’s efficient mechanisms for logging HTTP traffic.
