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.
