This can happen after an upgrade

stop your "Events Monitor" task.

You can do this from the server tab, then go to the point "Server tasks" on the left side. Right mouse click - stop task, and then look in your console.

Chances are your console will now show a proper compact, run  "load compact -c -v -n" without a target, if this works, then your DDM/Events config is either corrupt or just wrong.

The fix is easy, just go to the "Configuration" tab in your admin client.

On the left there is a point for "Monitoring configuration", open it.  There is an under point "Log Filters", just delete the contents of the view. There are other methods to do this too, but this is the most simple.

Now start your Events task using the server tab, tools on the side then "Start", "Event Monitor".
