What is AWS Cloudwatch synthetics?<\/span><\/strong>AWS synthetics is a tool powered by AWS Cloudwatch which allows you to create and manage canaries. It is a real time monitoring tool which helps you to detect problems by mimicking a real user behaviour.<\/p>\n

What are canaries?<\/strong><\/p>\n

Canary in the context of AWS cloudwatch is a small script that runs at regular intervals and simulates real user interactions on your website, endpoints, API etc.<\/p>\n

How do canaries work?<\/strong><\/p>\n

These scripts are written in Node.js language and run in a managed lambda environment.<\/p>\n

Why is lambda required here?<\/strong><\/p>\n

1.It hosts canary code.
\n2.Run it on a regular interval.
\n3.Manage the runtime environment.
\n4.Capture the artifacts and send them to the cloudwatch.<\/p>\n

Lets see the architecture of a website monitoring by cloudwatch synthetic canaries.<\/p>\n

\"Flow

This proactive system ensures that the Admin is alerted about website issues even before end users notice, leading to faster response times and a more seamless experience for visitors.<\/p><\/div>\n

Steps to create the Heartbeat monitoring for a Website.<\/strong><\/p>\n

1.Navigate to Aws cloudwatch service.<\/p>\n

2.Navigate to the Application signals(APM) and look for the Synthetic Canaries.<\/p>\n

\"Cloudwatch\"

Step 2<\/p><\/div>\n

3.Click on Create canary.<\/p>\n

\"create

Step 3<\/p><\/div>\n

4.Choose use a Blueprint and heartbeat monitoring.<\/p>\n

\"Use

Step 4<\/p><\/div>\n

5.Give your canary a custom name in lower case only and provide the URL that you want to monitor and tick the check box for taking snapshots.<\/p>\n

\"Custom

Step 5<\/p><\/div>\n

6.Choose your Node.js version and also you can see your website URL that you are going to monitor in the script under const urls.<\/p>\n

\"Node

Step 6<\/p><\/div>\n

7.Now select the schedule that you want to run and timeout for the canary.<\/p>\n

\"Schedule

Step 7<\/p><\/div>\n

8.Select the retention period of the canary data and select the S3 bucket in which you want data to be stored.<\/p>\n

\"S3

Step 8<\/p><\/div>\n

9.Now create a new role for S3 and configure the AWS cloudwatch alarms and create a new SNS topic to trigger the notifications or you can use an existing one.<\/p>\n

\"cloudwatch

Step 9<\/p><\/div>\n

10.Put the required tag to identify the resources after creating them and hit create canary.<\/p>\n

\"Tag

Step 10<\/p><\/div>\n

Now your canary is ready to monitor the desired URL, ADMIN will get notified whenever there is an error or anomaly detected.<\/strong><\/p>\n

In the dashboard you can look for the canary check status and success percentage of the URL.<\/p>\n
