Example of configuration for RDS CloudWatch collection​

You must create the following default settings to monitor the RDS CloudWatch and collect the related data.

whatap.conf
cloud_watch=on
aws_region=ap-northeast-2

# Create roles in AWS IAM and then copy and paste the role ARN value.
aws_arn=arn:aws:iam::999999999999:role/UpdateApp
cloud_watch_metrics=CPUUtilization,FreeableMemory,FreeStorageSpace,NetworkTransmitThroughput,NetworkReceiveThroughput

#Example of the instance name
cloud_watch_instance=pg-rds
