Description

Envoy has 2 logging management systems, the traditional one and the fine-grain file-based one.

https://www.envoyproxy.io/docs/envoy/latest/operations/admin#post--logging

The fine-grain logger provides the powerful file based logging management, but when we want to change the logging level, it is not user friendly like the traditional sub-system. One idea to improve it is to have a predefined map to achieve:

/logging?group=htttp:trace

so the group http will apply some log level setting to all the core http files in the predefined map to simplify the usage.

Research direction
Investigate the existing fine grain logging system in Envoy, particularly the admin handler for the /logging endpoint. Identify where the group mapping logic would be added and how to parse the 'group' query parameter. Review any comments or linked discussions for design constraints. Propose a predefined map and implement the parameter handling.
