 Useful for traffic accounting based on NGINX config logic (by location / server / user-defined-variables).

 ## How it works?

+This module keeps a list of **metrics** identified by `accounting_id` in its context.
 
 When a new **request** hits the server, the module will try to find its `accounting_id`, calculate statistics, and **aggregate** them into the corresponding metrics by `accounting_id`.
 
-For every period (defined by `interval`), a timer event is triggered, those metrics are rotated and exported to log files or sent to remote log servers.
