Amazon CloudWatch is AWS's monitoring service designed specifically for collecting and tracking metrics from AWS resources like RDS and EC2 instances.
Key capabilities of Amazon CloudWatch:
- Collects and tracks metrics from AWS services
- Monitors log files from applications and services
- Sets alarms to notify when metrics reach certain thresholds
- Automatically reacts to changes in AWS resources
- Provides a centralized view of resource performance
Why other options are incorrect:
- A. Amazon CloudFront: This is a content delivery network (CDN) service, not a monitoring service
- B. Amazon CloudSearch: This is a managed search service, not designed for metrics collection
- D. Amazon Config: This service tracks configuration changes and compliance, not performance metrics
CloudWatch is the primary AWS service for monitoring resource performance and collecting operational data.
