Good day Guys

I just implemented rate limiting.

Could someone please explain what

*42450 is / means

109154#109154 is / means

and what also

10.195 (I take it 10 is the size my bucket, but its the 195 I dont 

Here is the log entry:

2016/09/01 10:06:29 [error] 109154#109154: *42450 limiting requests, 
excess: 10.195 by zone "req_limit_per_ip", client:, 
server: default, request: "GET

Many thanks
