Name

ngx_req_status - Request status in nginx

Synopsis

http {
    req_status_zone server_name $server_name 256k;
    req_status_zone server_addr $server_addr 256k;

    req_status server_name server_addr;

    server {
        location /req-status {
            req_status_show on;

            allow 10.0.0.0/8;
            allow 127.0.0.1;
            deny all;
        }
    }
}

Directives

req_status_zone

syntax: req_status_zone name string size

default: None

context: http

Define a request status zone. Requests are grouped by the value of string specified in the second paramter.

req_status_zone server_addr "$server_addr:$server_port" 256k;

req_status

syntax: req_status zone1[ zone2]

default: None

context: http, server, location

Enables request status in this location. You can specify as many zones as needed.

req_status_show

syntax: req_status_show on

default: None

context: location

Enables the request status handler in this location. For example:

location /req-status {
    req_status_show on;

    allow 10.0.0.0/8;
    allow 127.0.0.1;
    deny all;
}

Then you can see the page by

curl http://127.0.0.1/req-status

It is plain text information like:
