CloudWatch Container Insights collects, aggregates, and summarizes metrics and logs from your containerized applications and microservices. The metrics include utilization for resources such as CPU, memory, disk, and network. The metrics are available in CloudWatch automatic dashboards. For a full list of Amazon ECS Container Insights metrics, see Amazon ECS Container Insights Metrics in the Amazon CloudWatch User Guide.
Operational data is collected as performance log events. These are entries that use a structured JSON schema that enables high-cardinality data to be ingested and stored at scale. From this data, CloudWatch creates higher-level aggregated metrics at the cluster and service level as CloudWatch metrics. For more information, see Container Insights Structured Logs for Amazon ECS in the Amazon CloudWatch User Guide.
