An AWS CLI command to tail a CloudWatch log group
Command that tails a CloudWatch Logs group directly into your terminal. Useful command to watch CloudWatch log groups without needing to go into the console. By default, the command returns logs from all associated CloudWatch Logs streams during the past ten minutes. Note that there is no guarantee for exact timestamp ordering of logs.
AWS CLI Command (You will need AWS CLI v2)
aws logs tail {LogGroupName} --follow --format json
