I have around 100 Target Groups.
I want to get alerted when any target group's hosts are unhealthy.
I don't want to create 100 CloudWatch alarms (1 per Target Group).
Is there a way to create a SINGLE CloudWatch alarm that will alert me ANY host behind ANY target group is unhealthy?
@marcin suggested Math Metrics, but no love. AWS has a max of 10 things you can do math on... I have more than 10 Target Groups :(
