What is the Expiry date of CloudWatch Logs Agent?

Question

EC2实例使用CloudWatch Logs Agent在CloudWatch日志中生成的日志文件是否有有效期限？

Answer 1

By default, log data is stored indefinitely. However, you can configure how long you want to store log data in a log group. Any data older than the current retention setting is automatically deleted. You can change the log retention for each log group at any time.
