You can monitor your Amazon ECS resources using Amazon CloudWatch, which collects and processes raw data from Amazon ECS into readable, near real-time metrics. These statistics are recorded for a period of two weeks so that you can access historical information and gain a better perspective on how your clusters or services are performing. Amazon ECS metric data is automatically sent to CloudWatch in 1-minute periods. For more information about CloudWatch, see the Amazon CloudWatch User Guide.
Amazon ECS provides free metrics for clusters and services. For an additional cost, you can turn on Amazon ECS CloudWatch Container Insights for your cluster for per-task metrics, including CPU, memory, and EBS filesystem utilization. For more information about Container Insights, see Monitor Amazon ECS containers using Container Insights.
CloudWatch Container Insights collects, aggregates, and summarizes metrics and logs from your containerized applications and microservices.
Container Insights will discover all the running containers in a cluster and collect performance data at every layer of the performance stack. Operational data is collected as performance log events. These are entries that use a structured JSON schema for high-cardinality data to be ingested and stored at scale. From this data, CloudWatch creates higher-level aggregated metrics at the cluster, service, and task level as CloudWatch metrics. The metrics include utilization for resources such as CPU, memory, disk, and network. The metrics are available in CloudWatch automatic dashboards. For information about the available metrics, see Amazon ECS Container Insights metrics in the Amazon CloudWatch User Guide.
Metrics collected by CloudWatch Container Insights are charged as custom metrics. For more information about CloudWatch pricing, see CloudWatch Pricing. Amazon ECS also provides monitoring metrics that are provided at no additional cost. For more information, see Monitor Amazon ECS using CloudWatch.
