Application Insights configuration web API

Question

我创建了一个库项目，用于将日志写入ApplicationInsights和表存储，并正在使用我的其他不同WebAPI项目。但由于某些原因，这些日志没有记录在Application Insights中，但它可以用于表存储。

private void AddTelemetryTarget(string instrumentationKey, LoggerEnumerations.LogLevel minLogLevel, LoggingConfiguration config)
{
try
{           ConfigurationItemFactory.Default.Targets.RegisterDefinition("ApplicationInsightsTarget", typeof(ApplicationInsightsTarget));
ApplicationInsightsTarget aiTarget = new ApplicationInsightsTarget();
aiTarget.InstrumentationKey = instrumentationKey;
aiTarget.Name = "ai";
var wrapper = new AsyncTargetWrapper(aiTarget, 5000, AsyncTargetWrapperOverflowAction.Grow);
config.AddTarget("TelemetryAsyncWrapper", wrapper);
//Applying logging rules.
LoggingRule rule = new LoggingRule("*", ConvertLogType(minLogLevel), aiTarget);
config.LoggingRules.Add(rule);
}
catch
{ }
}
private LogLevel ConvertLogType(LoggerEnumerations.LogLevel type)
{
switch (type)
{
case LoggerEnumerations.LogLevel.Error: return LogLevel.Error;
case LoggerEnumerations.LogLevel.Info: return LogLevel.Info;
case LoggerEnumerations.LogLevel.Warn: return LogLevel.Warn;
default: return LogLevel.Trace;
}
}

public async Task Log(string message, LoggerEnumerations.LogLevel type, Dictionary<string, string> customParams, Exception ex = null, bool isPayload = false)
{
LogEventInfo eventInfo = PopulateEventInfo(message, type, customParams, ex);
if (!isPayload)
{
_logger.Log(eventInfo);
}
else
{
_payloadLogger.Log(eventInfo);
}
}
private LogEventInfo PopulateEventInfo(string message, LoggerEnumerations.LogLevel type, Dictionary<string, string> customParams, Exception ex = null)
{
LogEventInfo eventInfo = new LogEventInfo();
eventInfo.Level = ConvertLogType(type);
eventInfo.Message = message;
eventInfo.LoggerName = this.GetType().ToString();
if (ex != null)
{
eventInfo.Exception = ex;
}
else if (eventInfo.Level == LogLevel.Error)
{
eventInfo.Exception = new Exception(message);
}
//Adding custom properties to LogEventInfo to display in Application insight 
if (customParams != null)
{
foreach (KeyValuePair<string, string> param in customParams)
{
eventInfo.Properties.Add(param.Key, param.Value);
}
}
return eventInfo;
}

Nuget软件包的版本是

Microsoft.ApplicationInsights.NLogTarget:2.13.1NLog:4.6.8

我将Application Insights添加为Connected Services，并从ApplicationInsights.config文件中删除了Instrumentation Key，在注册nlog目标时，我使用了web.config文件中的Instrumentation密钥，它开始工作。
