🔹 Amazon CloudWatch is a powerful monitoring tool that helps track AWS resources and applications in real time. Setting up CloudWatch Alarms ensures you get notified before issues impact your system. Let’s dive into how to configure one! 👇
🛠 Steps to Create a CloudWatch Alarm:
1️⃣ Go to AWS CloudWatch → Open the CloudWatch Console in AWS.
2️⃣ Select “Alarms” → “Create Alarm”
3️⃣ Choose a Metric → Select an AWS service (e.g., EC2 CPUUtilization, RDS FreeStorageSpace, Lambda Errors).
4️⃣ Set Thresholds → Define when the alarm should trigger (e.g., CPU > 80% for 5 mins).
5️⃣ Configure Actions → Choose an SNS topic to send notifications via email, SMS, or Lambda function.
