[OpenSIPS-Users] E_ACC_EVENT Question

[Ben Newlin]

If I’m understanding correctly, acc_extra variables are only used during message processing; they are not visible in event routes. Parameters passed to event routes are accessed using the $param() notation [1].

Per the ACC module docs [2]:


  *   Events accounting - log_name will be the name of the parameter in the event raised.

So I believe in your config it would be:

        #Extra Params
        $var(src_ip) = $param(source_ip);

        $var(dst_ip) = $param (destination_ip);

Note that the param name is the log name, not the tag.

As an additional note, your reference to the $si variable as a sanity check is not valid as that variable is also only available in a message processing route. Its value is not defined in an event route.

Hi Bogdan.  Thank you for getting back to me.  When we take a look at what populates, they are either incorrect (for example, src_ip is always 0.0.0.0, but we see it correct in the route block), or they are null.

Let me know if this helps.

Thank you,
Alex

Hi Alexander.

When you say "they don't seem to populate correctly", you mean they are NULL val, or wrong value?

Hi All. We are working on implementing the E_ACC_EVENT so we may use that for accounting purposes instead of the DB.  Now, most things appear to work as they should.  However, when we attempt to access the extra accounting fields, they don't seem to populate correctly (I've highlighted the extra variables).  Here is the config:

modparam("acc","extra_fields","evi: src_ip -> source_ip; dst_ip -> destination_ip)

event_route [E_ACC_EVENT]
{
        #log on entry
        xlog("L_INFO","entered event_route\n");

        #Default Params
        $var(method) = $param(method);

        #Extra Params
        $var(src_ip) = $acc_extra(src_ip);

        $var(source_test) = $si;

        $var(dst_ip) = $acc_extra(dst_ip);

        #log vars to test
        xlog("L_INFO","heres the ER variable: $var(source_test) and $var(src_ip)\n");

}

What am I missing?  Can someone point me in the right direction?  Any help is really appreciated.

Thank you,
Alex Perkins
