Once ingested, data points can be aggregated into statistics—such as average, minimum, maximum, and sum—over specific time windows. Teams should also ensure that alarms trigger runbooks or automation, transforming a simple notification into a remediated workflow that stabilizes the environment without manual intervention.
CloudWatch Metric Structure Components Overview
For low-level system visibility, such as CPU, memory, and disk activity, the CloudWatch Agent must be installed on the instance. Visualization and Alarming The value of collected data is realized through CloudWatch dashboards and alarms.
Standard resolution operates on a one-minute interval, while high-resolution metrics can be pushed at one-second intervals for near-real-time analysis. For instance, an alarm on `CPUUtilization` is useful, but an alarm on `HealthyHosts` directly correlates with user experience.
CloudWatch Metric Structure Components Breakdown
For example, a namespace might be `AWS/EC2`, while dimensions would differentiate between a specific instance ID. This flexibility allows teams to balance cost with operational needs, as high-resolution storage incurs higher fees.
