An AWS-hosted application on EC2 instances with Aurora database is encountering DECRYP_ERROR issues, only identified post-failure in automated tests. Implement a solution for real-time monitoring of these errors with minimal operational impact.
An AWS-hosted application on EC2 instances with Aurora database is encountering DECRYP_ERROR issues, only identified post-failure in automated tests. Implement a solution for real-time monitoring of these errors with minimal operational impact.
Explanation:
The correct answer is C. This solution employs Amazon CloudWatch Logs to create a metric filter with a pattern for the DECRYP_ERROR. By setting a CloudWatch alarm on this metric with a threshold >=1 and configuring it to send notifications via Amazon SNS, the company can achieve real-time monitoring and alerting with minimal operational overhead. Options A and B do not provide real-time monitoring, and option D involves more setup and maintenance. Thus, option C is the most efficient and straightforward solution.
