I sent the test requests from only one client.

I thought the rate is per IP address, not for whole server.

I configured as below:
limit_req_zone "all" zone=all:100m rate=2000r/s;
limit_req zone=all burst=100 nodelay;
but when testing,I use tool to send the request at: Qps:486.1(not reach 2000) I got the many many 503 error,and the error info as below:

2017/12/01 11:08:29 [error] 26592#37196: *15466 limiting requests, excess: 101.000 by zone "all", client: 127.0.0.1, server: localhost, request: "GET /private/rush2purchase/inventory/aquire?productId=product1 HTTP/1.1", host: "localhost"

Why excess: 101.000? I set it as 2000r/s ?

Hi there,

> what is the same "key " for all requests from different client ips for limit_conn_zone/limit_req_zone? I have no idea on this.

Any $variable might be different in different connections. Any fixed
string will not be.

So:

limit_conn_zone "all" zone=all...

for example.
