Topic 1 Question 452
A company needs to monitor its website’s availability to end users. The company needs a solution to provide an Amazon Simple Notification Service (Amazon SNS) notification if the website's uptime decreases to less than 99%. The monitoring must provide an accurate view of the user experience on the website.
Which solution will meet these requirements?
Create an Amazon CloudWatch alarm that is based on the website's logs that are published to a CloudWatch Logs log group. Configure the alarm to publish an SNS notification if the number of HTTP 4xx errors and 5xx errors exceeds a specified threshold.
Create an Amazon CloudWatch alarm that is based on the website's published metrics in CloudWatch. Configure the alarm to publish an SNS notification that is based on anomaly detection.
Create an Amazon CloudWatch Synthetics heartbeat monitoring canary. Associate the canary with the website's URL for end users. Create a CloudWatch alarm for the canary. Configure the alarm to publish an SNS notification if the value of the SuccessPercent metric is less than 99%.
Create an Amazon CloudWatch Synthetics broken link checker monitoring canary. Associate the canary with the website's URL for end users. Create a CloudWatch alarm for the canary. Configure the alarm to publish an SNS notification if the value of the SuccessPercent metric is less than 99%.

Heartbeat scripts load the specified URL and store a screenshot of the page and an HTTP archive file (HAR file). They also store logs of accessed URLs.
You can use the HAR files to view detailed performance data about the web pages. You can analyze the list of web requests and catch performance issues such as time to load for an item.
If your canary uses the syn-nodejs-puppeteer-3.1 or later runtime version, you can use the heartbeat monitoring blueprint to monitor multiple URLs and see the status, duration, associated screenshots, and failure reason for each URL in the step summary of the canary run report.
