Hobbit question for delaying warnings

Hi,

We have windows systems reporting to the hobbit server.  The memory test for them change frequently from green to yellow back to green, it does this all day throughout the day.

I was wondering if there is a way to sort of set a rule that states if the alarm has been, say yellow for 15minutes, then report it to the non-green hobbit page, if it is less then 15 minutes, then do not report it (show it) on the hobbit non-green page.

Thanks in advance for the help,
Dev Khemraj
