Stop Service notifications when other services are down

I have a set of UPS that I monitor, and they have traps that i monitor though services. I’m trying to find a way to have it not send out notices when certain other services are down. For example,

Host A has Services 1, 2 and 3. Were service 1 is the most critical and service 3 is the least critical. Is there a way to setup the services so that it will only send out the most critical service.

if service 1, 2 and 3 fails only service 1 sends out notice.
if service 2 and 3 fails only service 2 is sent.
and lastly is only service 3 fails it sends out the notice.

Thanks in advance, Any same configs would be greatly appreciated.

i never used them but i think service dependencies are what you’re looking for.

Thanks, after reading up on that I believe it will do want I need.
