Description: The status information includes the number of active connections, the total number of user requests that the server accepts has accepted, and the number of connections that the server handled has handled (typically server accepts and server handled are the same. That is, the number of user requests that have been accepted is the same as the number of connections that Nginx has processed, and the total amount of requests from the server requests users.

This module is not installed by default and can be configured when it is installed through the source code./configure Command plus --with-http_stub_status_module 这个参数这种方式启用该模块。

Second, about the module of the relevant configuration instructions

Configuration instance

1 location/basic_status {2    stub_status; 3 }

Location Configuration

This configuration can be enabled in the configuration module of HTTP or in a specific virtual host, and is typically enabled in a specific virtual host to count the actual access to the corresponding site. Specific where to turn on, see the actual situation
This configuration creates a simple Web page with basic status data which could look like as follows:

Active connections:291 Server accepts handled requests 16630948 16630948 31070465 reading:6 writing:179 waiting:10 6
instruction Description:
Syntax:stub_status;
default:-
Context:server, location
In versions prior to 1.7.5, the directive syntax required a arbitrary argument, for example, " stub_status on ".
before the 1.7.5 version, the syntax of the instruction requires an arbitrary parameter, such as " stub_status on "
