Guide: AWS CloudWatch Metrics
What is AWS CloudWatch Metrics?
AWS CloudWatch Metrics is a scalable AWS service that allows you to collect, view, and analyze metrics for your AWS resources and applications in real-time. It helps you gain system-wide visibility into resource utilization, application performance, and operational health.
Why is AWS CloudWatch Metrics important?
AWS CloudWatch Metrics is important because it allows you to monitor your applications, collect and track metrics, collect and monitor log files, and respond to system-wide performance changes. You can set alarms to notify you when specific thresholds have been breached, and every metric data point can be broken down into a minute or even seconds of granularity.
How does AWS CloudWatch Metrics work?
AWS CloudWatch Metrics works by collecting raw data points from your AWS resources and applications, and turning them into actionable, easy-to-interpret graphs and statistics. It provides you with system-wide visibility into resource utilization, operational performance, and demand patterns-including detailed usage metrics for each service you are provisioned with whether it be EC2 instances, DynamoDB tables, or RDS DB instances.
Exam Tips: Answering Questions on Metrics
1. Make sure to understand the difference between standard and high-resolution metrics: Standard metrics have a minimum granularity of one minute while high-resolution metrics can go down to one second.
2. Keep in mind the different statistic types that CloudWatch provides including Average, Sum, Minimum, Maximum, and SampleCount.
3. Know the limits of CloudWatch such as the fact that data points with a period of less than 60 seconds are available for 3 hours.
4. Remember that metrics are kept for 15 months, so you can retrieve historical data.
5. Finally, understand how to set alarms based on metric thresholds to alert you of potential issues.

Metrics practice test
Metrics are the fundamental concept in Amazon CloudWatch that represents a time-ordered set of data points. They are used to track and monitor the performance and utilization of AWS resources, such as EC2 instances, EBS volumes, and RDS databases. You can use CloudWatch to collect and analyze these metrics, set alarms based on the metrics' values, and visualize them in the form of graphs. Metrics can either be predefined by AWS for their services, or custom metrics that you can define and collect from your applications and resources. Some common metrics that AWS services provide include CPU Utilization, Network Packets, and Disk Read/Write Ops.
