Folder Monitor - file count condition question

I want to use the folder monitor/file count monitor to watch a folder on several remote servers. The folders should be empty if everything is okay, and if there is a problem on the server some files will be generated and the folder will no longer be empty. I've added a folder monitor with the folder path I want to keep an eye on, and the rule tests okay. I set the file count threshold to >=1 and rearm value to <=0. When the monitor checks the status it generates an alarm because it says "...does not contain any files which matches with the wildcard"

So it seems the folder monitor won't work the way I need to it. Unless I'm doing something wrong or there is a better way to keep tabs on this folder. Any ideas or suggestions?
