A Solutions Architect is designing a new web application on Amazon EC2. The system must make application-specific metrics, such as application security events, available to the SysOps teams.
How should the Solutions Architect enable this in the design?
A. Install AWS SDK on the application instances. Design the application to use the AWS SDK to log events directly to an Amazon S3 bucket.
B. Install the Amazon Inspector agent on the application instances. Design the application to store events in application log files.
C. Install the Amazon CloudWatch Logs agent on the application instances. Design the application to store events in application log files.
D. Install AWS SDK on the application instances. Design the application to use AWS SDK to log sensitive events directly to AWS CloudTrail.
Correct Answer: C
Explanation/Reference:
The unified CloudWatch agent enables you to do the following:
Collect more system-level metrics from Amazon EC2 instances across operating systems. The metrics can include in-guest metrics, in addition to the metrics for EC2 instances. The additional metrics that can be collected are listed in Metrics Collected by the CloudWatch Agent.
Collect system-level metrics from on-premises servers. These can include servers in a hybrid environment as well as servers not managed by AWS.
Retrieve custom metrics from your applications or services using the StatsD and collectd protocols. StatsD is supported on both Linux servers and servers running Windows Server. collectd is supported only on Linux servers. Collect logs from Amazon EC2 instances and on-premises servers, running either Linux or Windows Server.
You can store and view the metrics that you collect with the CloudWatch agent in CloudWatch just as you can with any other CloudWatch metrics. The default namespace for metrics collected by the CloudWatch agent is CWAgent, although you can specify a different namespace when you configure the agent.
The logs collected by the unified CloudWatch agent are processed and stored in Amazon CloudWatch Logs, just like logs collected by the older CloudWatch
Logs agent.
