CloudWatch Agent helps collect metrics and logs and push them to CloudWatch
Default namespace for metrics collected by the CloudWatch agent is CWAgent, although a different namespace can be configured
Logs collected by the unified CloudWatch agent are processed and stored in CloudWatch Logs
CloudWatch agent helps to
Collect internal system-level metrics from EC2 instances across operating systems. The metrics can include in-guest metrics, in addition to the metrics for EC2 instances.
Collect system-level metrics from on-premises servers. These can include servers in a hybrid environment as well as servers not managed by AWS.
Retrieve custom metrics from the applications or services using the StatsD and collectd protocols. StatsD is supported on both Linux servers and servers running Windows Server. collectd is supported only on Linux servers.
Collect logs from EC2 instances and on-premises servers, running either Linux or Windows Server.
Collect metrics for individual processes using the procstat plugins, which are stored in the procstat namespace.
CloudWatch agent can be installed, on Amazon Linux 2 and on all supported operating systems, manually or using AWS Systems Manager
CloudWatch agent needs to write metrics to CloudWatch, and IAM role for EC2 instances or IAM user for the on-premises server should be assigned.
AWS Certification Exam Practice Questions
Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated
