在应用程序中,如果Application Insights未记录或未处理异常,可以按照以下步骤来解决这个问题。
添加Application Insights SDK到你的项目中,可以通过NuGet包管理器或手动下载安装SDK。
在应用程序的启动代码中,初始化Application Insights。这可以在Global.asax.cs文件的Application_Start
方法中完成,或者在ASP.NET Core应用程序的Startup.cs文件的ConfigureServices
方法中完成。
// For ASP.NET WebForms
protected void Application_Start()
{
// Initialize Application Insights
TelemetryConfiguration.Active.InstrumentationKey = "Your-Instrumentation-Key";
TelemetryConfiguration.Active.TelemetryChannel.DeveloperMode = true;
TelemetryConfiguration.Active.TelemetryChannel.Flush();
}
// For ASP.NET Core
public void ConfigureServices(IServiceCollection services)
{
// Initialize Application Insights
services.AddApplicationInsightsTelemetry("Your-Instrumentation-Key");
}
try-catch
块来实现,将异常信息记录到Application Insights。try
{
// Your code that may throw an exception
}
catch (Exception ex)
{
// Log the exception to Application Insights
TelemetryClient telemetry = new TelemetryClient();
telemetry.TrackException(ex);
}
// For Serilog
Log.Logger = new LoggerConfiguration()
.WriteTo.ApplicationInsights(TelemetryConfiguration.Active, TelemetryConverter.Traces)
.CreateLogger();
// For NLog
var config = new LoggingConfiguration();
var applicationInsightsTarget = new ApplicationInsightsTarget
{
InstrumentationKey = "Your-Instrumentation-Key",
Name = "ApplicationInsights"
};
config.AddTarget("applicationInsights", applicationInsightsTarget);
config.LoggingRules.Add(new LoggingRule("*", LogLevel.Debug, applicationInsightsTarget));
LogManager.Configuration = config;
通过以上步骤,你可以确保Application Insights记录和追踪未处理的异常,并将其集成到你的应用程序中以进行监视和分析。
