Not really a Devops person but trying to learn on the go. Looking to create a datadog monitor if conditions are not met in the logs. Conditions are if A triggers and after 4 hours B doesnt trigger, then alert. Is this possible?

I looked through all the datadog docs but didnt find them helpful. Want to do logs("host:RANDOM service:Processor content:YYY) not sure how to continue.

logs("host:RANDOM service:Processor content:YYY) Then duration 4 hours logs("host:RANDOM service:Processor content:XXX) Alert is A triggers and after 4 hours B doesnt trigger then alert.
