Create a Log Group in CloudWatch Logs
When you install the CloudWatch Logs agent on an Amazon EC2 instance using the steps in previous sections of the Amazon CloudWatch Logs User Guide, the log group is created as part of that process. You can also create a log group directly in the CloudWatch console.
To create a log group
Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.
In the navigation pane, choose Logs.
Choose Actions, Create log group.
Type a name for the log group, and then choose Create log group.
