nginx и его status page

Стандартная страница статус nginx выглядит примерно так:

Active connections: 291
server accepts handled requests
  16630948 16630948 31070465
Reading: 6 Writing: 179 Waiting: 106

Описание, что для чего:

active connections -- number of all open connections including connections to backends
server accepts handled requests -- nginx accepted 16630948 connections, handled 16630948 connections (no one was closed just it was accepted), and handles 31070465 requests (1.8 requests per connection)
reading -- nginx reads request header
writing -- nginx reads request body, processes request, or writes response to a client
waiting -- keep-alive connections, actually it is active - (reading + writing)
