AWS CloudWatch Basics
Amazon CloudWatch is a web service that provides real-time monitoring to Amazon’s EC2 customers on their resource utilization such as CPU, disk and network. CloudWatch does not provide any memory, disk space, or load average metrics without running additional software on the instance.
With CloudWatch, you can monitor your AWS resources and the applications you run on AWS in real time. CloudWatch Events can send system events from AWS resources to AWS Lambda functions, Amazon SNS topics, streams in Amazon Kinesis, and other target types. CloudWatch Logs can monitor, store, and access your log files from Amazon EC2 instances, AWS CloudTrail, or other sources.
