    Study Notes

    Amazon CloudWatch Overview

    • Monitoring service for AWS cloud resources and applications hosted on AWS.
    • Collects and tracks metrics, monitors log files, and sets alarms to alert users.

    Access and Metrics

    • Accessed via API, AWS Management Console, command-line interface, and SDKs.
    • Metrics are time-ordered sets of data points; users can publish custom metrics.
    • Custom metrics can be categorized as either standard or high resolution.

    High-Resolution Metrics

    • High-resolution metrics have a resolution of 1 second, suitable for monitoring sub-minute activities.
    • Charged per call to PutMetricData; more frequent updates on high-resolution metrics incur higher costs.
    • Alarms can be set for high-resolution metrics with specific periods (10 or 30 seconds) or standard periods (multiples of 60 seconds).

    Namespaces and Dimensions

    • Metrics in different namespaces are isolated; prevents data aggregation from different applications.
    • Up to 10 dimensions can be defined for a single metric, specified as name-value pairs.
    • Different command formats required for dimension specification in put-metric-data versus get-metric-statistics.

    Command Examples

    • Command examples illustrate how to publish and retrieve metrics with specific dimensions and names.
    • For multi-dimensional metrics, all defined dimensions must be specified when retrieving statistics.

    Publishing Data Points

    • Use put-metric-data command to publish individual data points with a value and timestamp.
    • Multiple actions can publish sequential data points for a metric.

    Statistics and Alarms

    • Statistics represent aggregations of metric data over defined time periods.
    • Alarms can trigger actions based on metric values relative to defined thresholds, such as notifications to SNS or auto-scaling policies.

    CloudWatch Logs

    • Enables monitoring and troubleshooting of systems using existing logs from various sources, including EC2 instances and CloudTrail.
    • CloudWatch Logs allows for real-time monitoring and long-term log retention.
    • Metric filters can evaluate logs for specific terms or values.

    CloudWatch Events

    • Provides a near real-time stream of system events reflecting changes in AWS resources.
    • Enables the scheduling of automated actions using cron or rate expressions.
    • Can route events to target functions or services based on specific conditions.

    Developer Associate Exam Preparation

    • Understanding key API actions relevant to Amazon CloudWatch is essential for exam success.
    • Familiarity with commands, metric management, and log handling is crucial.
