Iam using dhcp-4.1.0 and also playing a little bit with logging at DHCPDISCOVER stage.
I dont read the whole thread, but iam stuck at the same point.
In my config i have something like this:
if option dhcp-message-type = 1 {
log(info,"discover");
}
It seems that the log-statemant is only executed if there are free leases available.
If there are no free leases available, then i also only see a DHCPDISCOVER ... no free leases
and the log-statement is not executed.
Best Regards,
Andre
