Monitoring CDN Performance in Azure

Question

"Hello Team,

We have recently implemented the CDN, and I would like to understand if there are any ways to monitor its performance effectively. Are there any existing dashboards or monitoring tools available in Azure that we can use to track key performance metrics, such as latency, request handling, and overall impact on application performance?

Please let me know if there are any recommended approaches or tools for this. Appreciate your guidance.

Thank you!"

Hi @Srinadh Reddy Meegada,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

Azure provides several effective tools and dashboards for monitoring CDN performance. You can utilize Azure Monitor, which integrates with Azure CDN to track key performance metrics such as latency, request handling, and overall application performance.

The Azure CDN offers several metrics that can be monitored, including:

• Total Latency: This metric measures the total time from when a client request is received by the CDN until the last response byte is sent from the CDN to the client.
• Request Count: This indicates the number of client requests served by the CDN.
• Response Size: This shows the number of bytes sent as responses from the CDN edge to clients.
• Bytes Hit Ratio: This percentage reflects the egress from the CDN cache against the total egress.

Additionally, you can access the Edge Performance Analytics dashboard, which tracks current and historical CDN traffic. This dashboard includes an interactive chart for visualizing key metrics and trends, as well as statistical information on CDN performance.

To set up alerts based on these metrics, you can navigate to the Monitoring section in the Azure portal and create new alert rules for the metrics you wish to track.
