Nginx Nginx status Waiting requests?

pamamolf · Jul 6, 2014

Hi

On Nginx stats i can see :
Code:
server      accepts    handled requests
 5719           5719            14106
Reading: 0 Writing: 1 Waiting: 8
Waiting 8?

Why?

read official docs at http://nginx.org/en/docs/http/ngx_http_status_module.html

and http://wiki.nginx.org/HttpStubStatusModule

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)

keepalive_timeout
http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout

Syntax:keepalive_timeout timeout [header_timeout];
Default:
keepalive_timeout 75s;
Context:http, server, location
The first parameter sets a timeout during which a keep-alive client connection will stay open on the server side. The zero value disables keep-alive client connections. The optional second parameter sets a value in the “Keep-Alive: timeout=time” response header field. Two parameters may differ.

The “Keep-Alive: timeout=time” header field is recognized by Mozilla and Konqueror. MSIE closes keep-alive connections by itself in about 60 seconds.
