Nov 08, 2022, is the publication date of an article discussing Amazon CloudWatch, a service that monitors AWS resources and can trigger alarms when metrics exceed certain thresholds. The author suggests using Lumigo to set up multiple CloudWatch Metric Alerts in less time than reading Amazon's documentation. Lumigo allows for easier setup of alerts with built-in integrations sending notifications to workflow tools without manual integration. The article creates an Amazon Lambda function that occasionally throws an error message and sets up a rule to run it periodically, creating a metric alert to notify when the error rate exceeds a specific threshold. The author demonstrates how to generate worlds and squirrels with AWS EventBridge, which triggers the Lambda on a regular schedule, and how to create a CloudWatch Metric Alert in Lumigo to send an email notification when the error rate spikes above a certain threshold.
