c# - Application Insights - 异常添加信息

Question

实际上，我在 ASP.NET Web API 2 中设置了应用程序见解，以按照步骤 Diagnose exceptions in your web apps with Application Insights 记录错误，一切工作正常，但是，我想为每个异常添加信息，例如 CustomerId、JobId 等。

因此，我希望通过 Azure Application Insights ( see this image ) 查看异常中的数据(调用堆栈或其他属性)。该信息可以帮助我检测应该使用哪些记录来尝试复制错误场景。

你能告诉我什么建议吗？

谢谢!

据我所知，TelemetryClient.TrackException 可以添加自定义属性。

添加这些属性后，您可以在 Azure Insights 门户中找到值。

更多关于如何在Web api中添加自定义属性的详细信息，您可以引用以下代码:

  public class AiExceptionLogger : ExceptionLogger
        {
            public override void Log(ExceptionLoggerContext context)
            {
                if (context != null && context.Exception != null)
                {//or reuse instance (recommended!). see note above
                    var ai = new TelemetryClient();
                    //Here you need get the CustomerId, JobId, and other. For example get the current user id
                    string re = HttpContext.Current.User.Identity.Name;

                    // Set up some properties:
                   //Here you need get what you need and add them to the properties
                    var properties = new Dictionary<string, string> {{ "Users", "vvvvv" } };
                        // Send the exception telemetry:
                    ai.TrackException(context.Exception, properties);
                }
                base.Log(context);
            }
        }

您可以在“查看所有属性”中找到它，如下所示:

But I have other question, How can I do to send data from my controller to "AiExceptionLogger". i.e: I have my controller a POST method Post(user, jobId), I want to add jobId to TrackException. Note: I don't want to use try{} catch(){} for every method in my controller, If I can add that information to context, it will be grat!. Thanks!

根据您的描述，我建议您可以尝试其他方式注册过滤器并覆盖 OnActionExecuted 方法。

在此方法中，您可以首先检查异常是否为空。如果异常不为 null，您可以从 HttpActionExecutedContext 获取 ActionArguments。

然后您可以在属性中添加此参数并将它们发送到 azure Application Insights。

更多详细信息，您可以引用以下代码:

WebApi配置:

public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services   

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            //config.Services.Add(typeof(IExceptionLogger), new AiExceptionLogger());

            config.Filters.Add(new AAA());
        }

        public class AAA : ActionFilterAttribute
        {

            public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
            {
                if (actionExecutedContext.Exception != null)
                {
                    var ai = new TelemetryClient();
                     //here get the arguments
                    string d1 = (string)actionExecutedContext.ActionContext.ActionArguments["id"];
                    var properties = new Dictionary<string, string> { { "Users", d1 } };
                    ai.TrackException(actionExecutedContext.Exception, properties);
                }
                base.OnActionExecuted(actionExecutedContext);
            }
        }

结果:
