I have many alerts but this issue with our new system is going to drive me crazy.
1. Alert on all nodes down. ( YES ) - tons of systems
2. Group A - 5 specific servers in a group --> If one of these five systems are down I don't want one from the all nodes and one from the specific group.
What came to my mind was something like firewall rules where your defining all the specific items first then a catch all at the bottom.
