RDS Proxy Metrics

Question

I am having a higher number of DatabaseConnectionRequests on the RDS proxy. I am not sure how should I interpret it? I tried the AWS documentation but it did not help:
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-proxy.monitoring.html

1) What is DatabaseConnectionRequests matric, what does it represent?
2) Does it represent connection Requests between proxy and database or between application and proxy?
3) What will be the impact on RDS if this metric will keep on getting higher and higher?

Answer

1.  How many connection request to have a connection from Proxy to your RDS
2. It represent connection Requests between proxy and database
3. The metric itself gives you an idea of how many connections per min you are trying to establish. Use with the metrics DatabaseConnections, DatabaseConnectionsSetupSucceeded, DatabaseConnectionsSetupFailed to give you a view of your capacity in the Database Connections.  RDS proxy can help you reuse connections set to your database to manage the Maximum database connections of your DB engine.
