Infrastructure Monitoring with Amazon CloudWatch

By: Ewere Diagboya

Overview of this book

CloudWatch is Amazon’s monitoring and observability service, designed to help those in the IT industry who are interested in optimizing resource utilization, visualizing operational health, and eventually increasing infrastructure performance. This book helps IT administrators, DevOps engineers, network engineers, and solutions architects to make optimum use of this cloud service for effective infrastructure productivity. You’ll start with a brief introduction to monitoring and Amazon CloudWatch and its core functionalities. Next, you’ll get to grips with CloudWatch features and their usability. Once the book has helped you develop your foundational knowledge of CloudWatch, you’ll be able to build your practical skills in monitoring and alerting various Amazon Web Services, such as EC2, EBS, RDS, ECS, EKS, DynamoDB, AWS Lambda, and ELB, with the help of real-world use cases. As you progress, you'll also learn how to use CloudWatch to detect anomalous behavior, set alarms, visualize logs and metrics, define automated actions, and rapidly troubleshoot issues. Finally, the book will take you through monitoring AWS billing and costs. By the end of this book, you'll be capable of making decisions that enhance your infrastructure performance and maintain it at its peak.

Monitoring Amazon EBS volume metrics

IOPS is a measure of the speed at which a disk can read and write information. The full meaning of IOPS is input/output per second. This means that the speed of the read and the write is measured in seconds. The speed at which data is read and written to the EBS volume determines the speed at which the data will be received by the application running within the EC2 instance, thereby impacting the experience that users using the application will receive. IOPS is one of the many metrics we monitor to keep track of the behavior of an Amazon EBS volume. Amazon EBS volume has a dashboard of various metrics and data that is captured to enable us to understand other behaviors of our EBS volume. We already mentioned previously that an EBS volume is irrelevant without an EC2 instance, meaning that the behavior of the EBS volume will be directly proportional to the metrics we find within the EBS volumes (all things being equal).
