It is checked as an event... but pops up as an alert.  @Hank21 

Also I'm on the newest OC200 controller.  

Hi @KimcheeGUN 

Thanks for posting in our business forum.

Can you disable this? So it should spam in your log.

If it shows up in an incorrect Event or Alert, it could be a bug on the controller. @Hank21 Please take a record of this.

I'm on the newest beta controller on the oc200.  
 

I just upgraded my very large L3 hosted linux controller and it doesn't do this.  

I uploaded a pic of what I woke up too. 
 

I was wrong... I was looking at another setting that was set as an Event.  It was checked as an Alert, like yours did.  My bad.  

But again, My L3 hosted Linux controller didn't give me this spam.  BUT my OC200 controller did.  

I also changed it to a Event just now.  Let's see if that stops it.  

This has stopped the DHCP Spam alerts.

BUT this did not happen to my recently upgraded Linux L3 controller.

This did happen to another OC200 site that I have.  That I had to change.
