cloudwatch alarm when aurora postgres failover event occurs

Question

Hello,

I'd like to get a cloudwatch alert setup when a failover event occurs. Does anyone know what I should be looking for in the postgresql.log or what cloudwatch metric I can use for this?

Thanks in advance!

It is better to use RDS event notification instead of CloudWatch.  
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_Events.html

Settings can be made in the following documentation methods.  
When setting up the system, select failover in the "Specific event categories" to be notified when a failover occurs.

Thank you both! I had no idea about event notifications like this. This is SO much better than figuring out how to do this via cloudwatch.
