Monitoring
AWS provides multiple services to monitor and manage your infrastructure and
applications on AWS. You can use services like Amazon CloudWatch
CloudWatch provides ready-to-use key performance indicators (KPIs) that you can use to monitor both CPU and disk utilization.
You can also create custom metrics
With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. AWS CloudTrail is enabled on all AWS accounts and records your account activity upon account creation. You can view and download the last 90 days of your account activity for create, modify, and delete operations of supported services without the need to manually set up CloudTrail.
