  • Hello Vikrantkale,

    An alert indicates that an abnormal rise in the failed request rate was detected. It's likely that there is some problem with your app or its environment.

    • The "See the analysis of this issue" button in the Notification email usually takes you to the Smart Detection blade of Application Insights in the Azure Portal, which gives you detailed information about the issue that raised the alert.
    • To investigate further, the links in each section will take you straight to a Search page filtered to the relevant requests, exception, dependency or traces.
    • Or you can open the Azure portal, navigate to the Application Insights resource for your app, and open the Failures blade, and diagnose Failures from there digging through Dependencies and other available Data.

    Please check if any of the above options help you in finding you the telemetry you need. I would also suggest you take a look at our detailed article covering various aspects of Smart Detection for Failure anomalies with alerting options.

    Additional Info:

    If you wish to receive more diagnostic information in the email itself, select "Get more detailed diagnostics" while configuring alerts. This way, you'll sometimes be able to diagnose the problem just from the data in the email.

    That being said, there's a slight risk that the more detailed alert could contain sensitive information, because it includes exception and trace messages. However, this would only happen if your code could allow sensitive information into those messages.

    If you still see issues however, please elaborate on what data you currently see in the Portal with relevant screenshots and information so we can assist you further.

    Hope this helps!
