Hi,

This is an example of an entry in the log, left by HttpLimitReqModule:

2013/10/27 10:00:11 [error] 1402#0: \*313355 limiting requests, excess:  
0.580  
by zone “zone1”, client: 20.147.43.103, server: [api.acme.com](http://api.acme.com), request:  
“GET  
/location/locate-ip?key=xxxx&ip=85.210.42.204 HTTP/1.1”, host:  
“[api.acme.com](http://api.acme.com)”

What does “excess: 0.580” mean exactly? What is the unit of that value?  
Requests? Requests per second?  
There is no information in the documentation, as far as I know.

Thanks in advance,

Brian
