If the incidents aren't showing up there are several things to check.
On the detection server check the incidents folder to see if the incidents are queuing up there. If they are, open a support case to determine the cause.
In the GUI check the system -> overview -> enforce and make sure the monitor controller is running. If it isn't, start it.
If the monitor controller was runing, restart it.
If that doesn't fix the problem, restart all the servers.
If that doesn't fix the problem, open a support case.
