Hi,

I’m trying to use a perl handler to count the global number of GET/POST  
requests issued towards the server (the existing rate/connection limit  
modules are of no use to me as they are per-source).

The main problem I’m facing is not being able to reset the counter every  
second - I tried installing a timer function as the signal handler for  
SIGALRM, but when an alarm is received the worker process exists saying  
“worker process 73712 exited on signal 14”;

Is there a way to make the worker process pass SIGALRM handing to  
embedded perl?  
Are there any other ideas of how to achieve the same goal, of defining a  
function within that perl handler memory space that executes every 1  
second without blocking nginx?

Thanks!  
Yuri
