NGINX status page

The ngx_http_stub_status_module module provides access to basic status information. This is the default module active in the url /nginx_status in the status port (default is 18080).

This controller provides an alternative to this module using the nginx-module-vts module. To use this module just set in the configuration configmap enable-vts-status: "true".

To extract the information in JSON format the module provides a custom URL: /nginx_status/format/json
