CloudWatch Logs resources and operations
In CloudWatch Logs the primary resources are log groups, log streams and destinations. CloudWatch Logs does not support subresources (other resources for use with the primary resource).
Understanding resource ownership
The AWS account owns the resources that are created in the account, regardless of who created the resources. Specifically, the resource owner is the AWS account of the principal entity (that is, the root account, an IAM user, or an IAM role) that authenticates the resource creation request. The following examples illustrate how this works:
Managing access to resources
A permissions policy describes who has access to what. The following section explains the available options for creating permissions policies.
Specifying policy elements: Actions, effects, and principals
For each CloudWatch Logs resource, the service defines a set of API operations. To grant permissions for these API operations, CloudWatch Logs defines a set of actions that you can specify in a policy. Some API operations can require permissions for more than one action in order to perform the API operation.
Specifying conditions in a policy
When you grant permissions, you can use the access policy language to specify the conditions when a policy should take effect. For example, you might want a policy to be applied only after a specific date. For more information about specifying conditions in a policy language, see Condition in the IAM User Guide .
CloudWatch Logs IAM Policy
Before your jobs can send log data to CloudWatch Logs, you must create an IAM policy to allow your container instances to use the CloudWatch Logs APIs, and then you must attach that policy to ecsInstanceRole .
Installing and configuring the CloudWatch agent
After you have added the ECS-CloudWatchLogs policy to your ecsInstanceRole, you can install the CloudWatch agent on your container instances.
Viewing CloudWatch Logs
After you have given your container instance role the proper permissions to send logs to CloudWatch Logs, and you have configured and started the agent, your container instance should be sending its log data to CloudWatch Logs. You can view and search these logs in the AWSManagement Console.
