Handling Azure CDN Failures

Question

Hello everyone!

I am currently using Azure CDN to accelerate the delivery of static content for our website. Recently, we have encountered some issues where the CDN service seems to be experiencing failures, resulting in slow loading of static resources and negatively impacting user experience.

CDN Failure Detection: What are the best methods to effectively monitor and detect when the CDN is down? Are there any recommended tools or methods?

Hi qy.product,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

Here are some recommended methods and tools:

Azure Monitor: Set up alerts for key metrics like Byte Hit Ratio, Request Count, Response Size, and Total Latency. This helps you detect issues early and respond quickly.

Diagnostic Logs: Enable diagnostic logs for your CDN endpoint. These logs provide detailed information about every request that the CDN receives1. You can export these logs to Azure Storage, Event Hubs, or Log Analytics for further analysis.

Azure Resource Health: Use Azure Resource Health to monitor the health of your CDN resources. It provides actionable guidance to troubleshoot problems and can alert you to any ongoing issues with the CDN service.
