Everything is working as expected here. You should have been able to see an active alert about 192.168.4.201 being down in the Status tool of the web interface, between 11:24:40 and 11:36:15 on the 17th (unless you have filtered out these types of alerts from your status tool preferences).
So what does `alertengine.log` say in the same time period?
