ILogger is not logging exceptions to the app insights. .Net Framework 4.8


I have written a error handling framework using ILoggerFactory in .Net Framework 4.8
It supports multiple providers including Application Insights.

Recently I checked the Application Insights Logs and observed that none of my logs are not logging into the app insights.

  1. I was in the correct directory
  2. I have set data sampling to 100%
  3. I have configured the correct connection string
  4. I have installed Fiddler and checked if the request is hitting the Ingestion Endpoint and it does, but it had no response body.Image 1
  5. When called the IngestionEndpoint via powershell, it appeared in the portal.and it had a response body. Image 2
  6. My Code
public AbcExceptionLogger(string categoryName)
{
    _categoryName = categoryName;
    var minimumLogLevelSetting = ConfigurationManager.AppSettings["MinimumLogLevel"];
    if (!Enum.TryParse(minimumLogLevelSetting, true, out _minimumLogLevel))
    {
        _minimumLogLevel = LogLevel.Warning; // Default to Warning if the setting is not a valid LogLevel
    }

    // Create a new logger factory instance
    _loggerFactory = new LoggerFactory();
    var loggerProviderKey = ConfigurationManager.AppSettings["LoggerProvider"];

    if (loggerProviderKey == "ApplicationInsights")
    {
        var appInsightsConnectionString = ConfigurationManager.AppSettings["ApplicationInsights:ConnectionString"];
        //if (!string.IsNullOrEmpty(appInsightsConnectionString))
        //{
        //    IOptions<TelemetryConfiguration> telemetryConfigurationOptions = Options.Create(new TelemetryConfiguration()
        //    {
        //        ConnectionString = appInsightsConnectionString,
        //        TelemetryInitializers = { new AbcTelemetryInitializer() }
        //    });

        //    IOptions<ApplicationInsightsLoggerOptions> applicationInsightsLoggerOptions = Options.Create(new ApplicationInsightsLoggerOptions());


        //    // Add the ApplicationInsightsLoggerProvider to the logger factory
        //    _loggerFactory.AddProvider(new ApplicationInsightsLoggerProvider(
        //        telemetryConfigurationOptions,
        //        applicationInsightsLoggerOptions));
        //}

        var telemetryConfiguration = TelemetryConfiguration.CreateDefault();
        telemetryConfiguration.ConnectionString = appInsightsConnectionString;

        var telemetryInitializer = new AbcTelemetryInitializer();
        telemetryConfiguration.TelemetryInitializers.Add(telemetryInitializer);

        var telemetryConfigOptions = Options.Create(telemetryConfiguration);

        var options = new ApplicationInsightsLoggerOptions();
        var appInsightsLoggerOptions = Options.Create(options);


        telemetryConfiguration.TelemetryChannel = new InMemoryChannel
        {
            DeveloperMode = true
        };

        var aiLoggerProvider = new ApplicationInsightsLoggerProvider(telemetryConfigOptions, appInsightsLoggerOptions);

        _loggerFactory.AddProvider(aiLoggerProvider);


    }

    else if (loggerProviderKey == "Serilog")
    {
        // Create a new logger that enriches log events with the category name
        var serilogLogger = SerilogLoggerSingleton.Instance.ForContext("CategoryName", _categoryName);

        _loggerFactory.AddProvider(new Serilog.Extensions.Logging.SerilogLoggerProvider(serilogLogger));
    }
    else if (loggerProviderKey == "Log4Net")
    {
        //Add Log4Net provider to the logger factory
        _loggerFactory.AddProvider(new Log4NetProvider());
    }
    else
    {
        // Add the default logger provider to the logger factory

    }

    // Create a new logger instance using the logger factory
    _logger = _loggerFactory.CreateLogger(_categoryName);

}
public void Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter)
{
    
    if (!IsEnabled(logLevel))
    {
        return;
    }

    // Create a new logger instance using the logger factory
    //var logger = _loggerFactory.CreateLogger(_categoryName);

    // Log the message using the logger instance
    _logger.Log(logLevel, eventId, state, exception, formatter);

}

My AbcTelemetryInitializer

public class AbcTelemetryInitializer: ITelemetryInitializer
{
    public void Initialize(ITelemetry telemetry)
    {
        var httpContext = HttpContext.Current;
        if (httpContext != null)
        {
            var request = httpContext.Request;

            // Add context data from HttpContext
            telemetry.Context.GlobalProperties["HttpMethod"] = request.HttpMethod;
            telemetry.Context.GlobalProperties["Url.Scheme"] = request.Url.Scheme;
            telemetry.Context.GlobalProperties["Url.Host"] = request.Url.Host;
            telemetry.Context.GlobalProperties["Url.AbsolutePath"] = request.Url.AbsolutePath;
            telemetry.Context.GlobalProperties["Url.AbsoluteUri"] = request.Url.AbsoluteUri;
            telemetry.Context.GlobalProperties["Url.Query"] = request.Url.Query;
            telemetry.Context.GlobalProperties["Url.IsDefaultPort"] = request.Url.IsDefaultPort.ToString();
            telemetry.Context.GlobalProperties["DomainName"] = request.Url.Host;

            // Add session ID if available
            var sessionId = httpContext.Session?.SessionID;
            if (sessionId != null)
            {
                telemetry.Context.GlobalProperties["SessionId"] = sessionId;
            }

            //Add browser info
            var browser = request.Browser;
            telemetry.Context.GlobalProperties["User.Browser"] = string.Format("{0} {1}", browser.Browser, browser.Version);
            telemetry.Context.GlobalProperties["User.Platform"] = browser.Platform;
            telemetry.Context.GlobalProperties["User.Agent"] = request.UserAgent;
            telemetry.Context.GlobalProperties["User.IsMobile"] = browser.IsMobileDevice.ToString();

        }

        // Add module id if available
        var moduleID = ConfigurationManager.AppSettings["ModuleID"];
        if (!string.IsNullOrEmpty(moduleID))
        {
            telemetry.Context.GlobalProperties["ModuleId"] = moduleID;
        }
        // Add module name if available
        var moduleName = ConfigurationManager.AppSettings["ModuleName"];
        if (!string.IsNullOrEmpty(moduleName))
        {
            telemetry.Context.GlobalProperties["ModuleName"] = moduleName;
        }

        // Add trace ID if available
        var traceId = System.Diagnostics.Trace.CorrelationManager.ActivityId;
        if (traceId != Guid.Empty)
        {
            telemetry.Context.GlobalProperties["TraceId"] = traceId.ToString();
        }

        telemetry.Context.GlobalProperties["MachineName"] = Environment.MachineName.ToString();
    }
}

Solution

  • Need to have Tls12 in order to communicate with the ingestion end point. After setting this it worked

      System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
