How to setup a Cloud Watch Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report Amazon CloudWatch a key component of Amazon Web Services (AWS) is a service for real-time monitoring. Designed to empower users with vital data and actionable insights. It facilitates the continuous monitoring of applications, and performance adjustments across systems. It collects operational data in the form of logs, metrics and events. It also offers users a perspective on AWS resources, applications, and services operating within the AWS environment. Table of ContentComponents Of Cloud Watch Installing and Configuring AWS CloudWatch Agent on EC2 Instances Using AWS CLIHow To Setup AWS Cloud Watch AWS Configuration for CloudWatch LogsHow to Setup AWS CloudWatch AlarmsConclusionFrequently Asked Questions (FAQs) On Cloud Watch Components Of Cloud Watch EC2 (Elastic Compute Cloud): Before starting with CloudWatch we must know what is EC2 It is the Amazon Web Service we use to create and run virtual machines in the cloud (we call these virtual machines 'instances').To set CloudWatch we must have one EC2 instance running on your machine. If you don't know how to launch an EC2 instance you can refer to this article. Resource Groups: AWS Resource Groups lets us organize all the resources such as EC2 instances, RDS database, and S3 buckets into groups using tags that we define while launching/creating instances services. It is a collection of resources that match the resource types specified in a query, and share one or more tags or portions of tags.Cloudwatch Logs: CloudWatch Logs allows us to see all of our logs, regardless of their source, as a single and consistent flow of events ordered by time with the help of Graphs.Cloudwatch Alarms: CloudWatch Alarms allow us to set different types of alarms which notify us if any Matric goes above the threshold (will be set while creating an alarm).Installing and Configuring AWS CloudWatch Agent on EC2 Instances Using AWS CLIFor detailed steps and best practices on installing and configuring the AWS CloudWatch agent on EC2 instances using the AWS CLI please refer to our comprehensive guide on Installing and Configuring AWS CloudWatch Agent on EC2 Instances Using AWS CL How To Setup AWS Cloud Watch In this architecture we illustrate the essential components involved in setting up AWS CloudWatch for monitoring and alerting your AWS resources effectively The architecture for setting up AWS CloudWatch starts with the user accessing the AWS Management Console. From there, the user can manage various AWS services, including CloudWatch, to monitor their resources effectively. In this setup an Amazon EC2 instance acts as the primary resource being monitored. This instance continuously generates performance metrics such as CPU utilization and network traffic which are then sent to CloudWatch. Step 1: Go to https://aws.amazon.com/ and Sign in.Step 2: In the Search Bar, search for EC2 as shown below.EC2Step 3: After clicking on EC2 from search bar you will land on EC2 dashboard where all the stuff about EC2 is displayed.
