CloudWatch Monitoring Supported AWS Services

  • CloudWatch offers either basic or detailed monitoring for supported AWS services.
  • Basic monitoring means that a service sends data points to CloudWatch every five minutes.
  • Detailed monitoring means that a service sends data points to CloudWatch every minute.
  • If the AWS service supports both basic and detailed monitoring, the basic would be enabled by default and the detailed monitoring needs to be enabled for details metrics

AWS Certification Exam Practice Questions

  • Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
  • AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
  • AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated
  • Open to further feedback, discussion and correction.

  2. The answer for question 5 is D.

    it can not be B., you said in your notes and as it is on AWS documentation, basic monitoring is enabled by default. You can only optionally for with more cost enable the Detailed monitoring at launch configuration using the EC2 console or later using CLI.

    Enabling Detailed Monitoring

    You can enable detailed monitoring on an instance as you launch it or after the instance is running or stopped.

    To enable detailed monitoring for an existing instance using the console

    Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

    In the navigation pane, choose Instances.

    Select the instance, choose Actions, CloudWatch Monitoring, Enable Detailed Monitoring.

    In the Enable Detailed Monitoring dialog box, choose Yes, Enable.

    Choose Close.

    To enable detailed monitoring when launching an instance using the console

    When launching an instance using the AWS Management Console, select the Monitoring check box on the Configure Instance Details page.

    To enable detailed monitoring for an existing instance using the AWS CLI

    Use the following monitor-instances command to enable detailed monitoring for the specified instances.

    1. From Auto Scaling Documentation
      By default, basic monitoring is enabled when you create a launch configuration using the AWS Management Console and detailed monitoring is enabled when you create a launch configuration using the AWS CLI or an API.

  3. Q1) What is the minimum time Interval for the data that Amazon CloudWatch receives and aggregates?
    As per below information, shouldn’t the minimum be 1 sec?

    Source: https://aws.amazon.com/cloudwatch/faqs/

    The minimum resolution supported by CloudWatch is 1-second data points, which is a high-resolution metric, or you can store metrics at 1-minute granularity. Sometimes metrics are received by Cloudwatch at varying intervals, such as 3-minute or 5-minute intervals. If you do not specify that a metric is high resolution, by setting the StorageResolution field in the PutMetricData API request, then by default CloudWatch will aggregate and store the metrics at 1-minute resolution.
