# Container Insights performance log events for Amazon ECS
<a name="Container-Insights-reference-performance-logs-ECS"></a>

The following are examples of the performance log events that Container Insights collects from Amazon ECS.

These logs are in CloudWatch Logs, in a log group named `/aws/ecs/containerinsights/CLUSTER_NAME/performance`. Within that log group, each container instance will has a log stream named `AgentTelemetry-CONTAINER_INSTANCE_ID`.

You can query these logs using queries such as `{ $.Type = "Container" }` to view all container log events. 

**Type: Container**

```

	"Version":"0",
	"Type":"Container",
	"ContainerName":"sleep",
	"TaskId":"7ac4dfba69214411b4783a3b8189c9ba",
	"TaskDefinitionFamily":"sleep360",
	"TaskDefinitionRevision":"1",
	"ContainerInstanceId":"0d7650e6dec34c1a9200f72098071e8f",
	"EC2InstanceId":"i-0c470579dbcdbd2f3",
	"ClusterName":"MyCluster",
	"Image":"busybox",
	"ContainerKnownStatus":"RUNNING",
	"Timestamp":1623963900000,
	"CpuUtilized":0.0,
	"CpuReserved":10.0,
	"MemoryUtilized":0,
	"MemoryReserved":10,
	"StorageReadBytes":0,
	"StorageWriteBytes":0,
	"NetworkRxBytes":0,
	"NetworkRxDropped":0,
	"NetworkRxErrors":0,
	"NetworkRxPackets":14,
	"NetworkTxBytes":0,
	"NetworkTxDropped":0,
	"NetworkTxErrors":0,
	"NetworkTxPackets":0
}
```

**Type: Task**

Even though the units for `StorageReadBytes` and `StorageWriteBytes` are in Bytes/Second, the values represent the cumulative number of bytes read from and written to storage, respectively.
