How to control the total requests in Ngnix

[tongshushan at migu.cn]

Hi there,

I have combined the client ip concurrency and cluster concurrency(total requests) together as below ,seems it works as expected.

limit_req_zone $binary_remote_addr zone=one:10m rate=10r/s; # one client ip concurrency
limit_req_zone "all" zone=all:20m rate=2000r/s; #cluster concurrency
server {
location /private/rush2purchase/ {                  
                            proxy_pass http://my_server/private/rush2purchase/;
                            proxy_set_header Host $host:$server_port;    
                            limit_req zone=one burst=15 nodelay;
                            limit_req zone=all burst=3000 nodelay;
         }
} 

Thanks all guys.

Yes.

Yes.
 
The server can control how long it waits before starting to process a
request (rate) and how many requests it will process quickly (burst). It
cannot control when the requests are sent to it.
