[SR-Users] Kamailio invite counter

[Ali Taher]

Hi Alex,

 

I need to limit the number of requests received within 1 second, meaning that if the number of request during 1 second exceeds a certain limit(let’s say 1000 call per second), these requests must be blocked.

How can I reset the counter every one second to achieve this?

 

Thanks,

Ali

Ali,

 

$var variables do not persist outside the scope of the processing of a single SIP message. They live in the private memory of every receiver process.

 

Take a look at the 'htable' or 'statistics' modules.

Hello,

 

I want to define a counter  that increase in every invite.

I tried the below :

 

if (is_method("INVITE"))

                {      

$var(u)=$var(u)+1;

xlog("L_INFO","Counter : $var(u) " );

}

 

But the counter is reset to 1 randomly (even before restarting kamailio service)

 

How can have a proper counter that count invite messages.

 

Thanks

Ali
