This repository contains the Lambda function built with serverless application model(aka SAM) that monitors web URLs asynchronously, capture response times & response codes in cloud watch and enables slack notifications during 4XX & 5XX failures of the URLs and also a restoration notification once the service is restored.

Approx. AWS costs for lambda to monitor 10 URLs with the scheduled frequency of 5 mins. Kindly note that this is just an estimation. Actuals might differ and subject to the number of URLs that you add to monitor. Estimation is done through Link

• Maintains the state of the URL
• Slack Notifications when web URLs response code are not equal to 200
• Slack Notifications, once the URL is back online
• Response times of the web URLs are shipped to cloud watch. You can optionally enable custom metrics and log aggregation to elastic search(optional, might incur additional costs).
• Cloudwatch Alarms(optional, might incur additional costs).
• Easy to adjust the monitoring scheduled frequency
• Easy to add and remove URLs by just adding/removing them from config file(config.yaml) available in this repository
• Very Low cost monitoring solution
• Easy to customize the source code and CI/CD solution on Jenkins is already in place.
