Exceptions in web applications can be reported to Application Insights. You can associate failed requests with exceptions and other points in time, both on the client and on the web, to quickly evaluate the causes. In this article, you’ll learn how to set up exception reporting, explicitly report exceptions, diagnose crashes, and more.

Configure Exception Reporting

You mentioned that new exceptions can be added to Application Insights, which usually occur on the server or client. Depending on the platform your application is primarily running on, you will need an appropriate proxy or SDK.

Server-side

For the server application to report exceptions, select the following scenarios:

Client Side

The JavaScript SDK allows you to generate malicious client-side reporting of exceptions thrown in web browsers. To configure an exception when sending customer reports, see Application Insights for Web.

Frameworks

Some People Frameworks applications require additional configuration, consider the following technologies:

Diagnosing Exceptions With Visual Studio

Open the mobile app solution in Visual Studio. Run someone’s application either on your server or on your development machine using F5. Rethrow the exception.

Open the Application Insights search telemetry window in Visual Studio. While debugging, select the Application Insights drop-down menu.

Select the exception report if you want to view its stack trace. To open the corresponding code file, select the line link in the add trace.

Diagnose Errors Using The Azure Portal

Application Insights includes an Application Performance Management (APM) feature designed to help diagnose errors in monitored computer software. First, in the Bugs section, select your own option from the Application Insights Blog menu under Exploration.
You’ll see the types of error rates for your requests, how they fail, and a lot of information about the impact on users. In the overview, you can see some of the most useful distributions specific to the selected failed operation, including the main different response codes, the three most common examples of exceptions, and the three types of dependencies that most often fail.

Choose the appropriate link to get representative validation samples for each of these subsets.Operations. Typically, as an example of diagnosing exceptions, you can choose the number of a specific exception, which is displayed on the tab “Cross-cutting details”:

Alternatively, instead of viewing exceptions for a specific failed process, you can start by viewing global exceptions, preferably by turning off the Exceptions tab. Here you can see all exceptions thrown for your monitored application.

Custom Tracking And Registration Data

To get historical diagnostics for your application, anyone can inject code to send their own telemetry. Your business telemetry or log data is in a visible diagnostic search along with the request, form submission, and other automatically retrieved data.

To view these events, use Search to open the remaining menu, select the “Event Types” drop-down menu, then select “Custom Event”, “Track”, or “Exception”.

How To Get POST Data

Request not enabled. You see the data sent to your application during the POST call. Reported excellent data on this occasion:

Capturing Exceptions And Related Diagnostic Data

Won’t you first see all the downgrades that cause errors in your software package in the portal? You will see all browser terms (if you use the JavaScript SDK on all your web pages). But most web exceptions are caught by IIS and you need to write a small piece of code to see them.

Easiest Way To Explicitly Report Exceptions

The way is to put a big trackException() call in the diff handler.

Try

var telemetry = brand new TelemetryClient();

To attempt

    // ...

capture (exclusion for example)

    var is immovable t=new line>
 dictionary
    
        ["user"] = currentgame.user.count
    ;

    // send exception telemetry:
    telemetry.TrackException (e.g. properties, telemetry metrics);

Dim equals New TelemetryClient

To attempt
    MDR...
Catch your ex as an exception
    'Set up some properties:
    DimProperties means new dictionary (from string, string)
   Properties .Add("game", currentgame.name)

    Dim Measures = New dictionary (double)
 string, measurements.Add("user", currentgame.user.count)

    do not send telemetry:
 Exception telemetry. TrackException (e.g. properties, metrics)
Try Final Properties

Open Lesson ExampleController: ApiController

    hidden _telemetryClient read-only;

 telemetryclient public ExampleController(TelemetryClient telemetryClient)
    
        _telemetryClient is telemetryClient;
