The ngx_http_stub_status_module module provides access to basic status information.

This module is not built by default, it should be enabled with the --with-http_stub_status_module configuration parameter.

Example Configuration

location /basic_status {
    stub_status;
}

This configuration creates a simple web page with basic status data which may look like as follows:

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

Directives

The basic status information will be accessible from the surrounding location.

In versions prior to 1.7.5, the directive syntax required an arbitrary argument, for example, “stub_status on”.

Data

The following status information is provided:

Active connections

The current number of active client connections including Waiting connections.

accepts

The total number of accepted client connections.

handled

The total number of handled connections. Generally, the parameter value is the same as accepts unless some resource limits have been reached (for example, the worker_connections limit).

requests

Reading

The current number of connections where nginx is reading the request header.

Writing

The current number of connections where nginx is writing the response back to the client.
