CloudWatch Agent
The CloudWatch Agent is a software that can be installed on your instances to collect system-level metrics and logs. This agent can be used on both EC2 instances and on-premises servers. It allows for more detailed monitoring and extends CloudWatch's functionality by collecting additional metrics such as memory usage, disk usage, and application logs. The CloudWatch Agent is essential for organizations that require in-depth monitoring of their AWS infrastructure and are looking to gain valuable insights about their system performance. Configuration of the CloudWatch Agent is done using a JSON file, which includes the specific metrics and logs to be collected. Once the data is collected, it is sent to Amazon CloudWatch for visualization, analysis, and alarm setup.
