utils::statistics::Rate Struct Reference

#include <userver/utils/statistics/rate.hpp>

Detailed Description

Rate metrics (or "counter" metrics) are metrics that only monotonically increase or are reset to zero on restart. Some monitoring systems give them special treatment with regard to maintaining proper non-negative derivative.
