=head1 NAME

ngx_http_stub_status_module - Module ngx_http_stub_status_module




=head1



The C<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
C<--with-http_stub_status_module>
configuration parameter.




=head1 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

B<context:> I<server>


B<context:> I<location>





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

the directive syntax required an arbitrary argument, for example,
“C<stub_status on>”.
