User-Level Traffic Statistics and Dynamic Rate Limiting
GOST's Observer component collects connection and traffic statistics. When configured, it periodically reports total input/output bytes as events. The Limiter component enforces connection and traffic limits.
Sometimes finer-grained traffic management is needed. For example, an authenticated proxy service may require per-user traffic statistics or rate limiting, possibly with dynamic adjustments based on real-time usage. Since different scenarios may have complex logic, GOST doesn't provide built-in user-level limiting — instead, it exposes a plugin interface for custom implementations.
