controller_log_client

Module

mod_logging

Controller to log UI errors and events.

The user-agent can post JSON events to this controller. The events will be logged in the admin-ui log and can be viewed in the admin interface.

Events are collected in a ring buffer with de-duplication and periodic draining to the admin-ui log to prevent overload.
