I try to modify our existing EC2-monitors (i want to change user alert groups), with a bulk action, but the modification doesn't seem to happen. I also tried the same with creating a rule, and replace the user alert groups that way, but also that fails. For our server monitors this works both ways, but on our windows-machine EC2 monitors nothing changes with a bulk action or rule.
Any idea what could cause this? Could something be blocked on windows-level? What's the mechanism behind the bulk actions and/or rules?
