A bit like this. If a trap is received sysmon goes out and checks
that device. There has to be some rules for how to check the device
and how to clear it. I believe that, if possible, these rules should
be defined by the user. Some obvious rules could be preprogrammed like

Right on. This is exactly what I'm after. One thing that would be nice
though is self defined variables like attack, decay and duration. But it
could be a bit to much with this.
If you need beta testers I'm one of them.
