Watching the number of requests made to an Azure App Service can help you know when downstream errors are occurring and help you prevent your app service from being overwhelmed. Blue Matador automatically watches the Requests metric for anomalous request counts.


    By itself, higher request count is probably not a cause for concern. However, when correlated with other issues in your infrastructure, you may see the following effects:

    • Increased error rates in downstream services
    • Degraded application performance for your app service when it receives too many requests



    Abnormal request count is often a symptom of issues in downstream services that rely on your app service. To troubleshoot, follow these steps:

    1. If you see performance degradation in the affected app service or any other app service using the app service plan, temporarily scale out (or scale up if you are at the limits of your pricing tier) while you fix the issue.
    2. Enable and check the diagnostic logs for your app service to find which endpoints are being affected. Once you’ve found the problem endpoints, check the client that is calling them for errors.
