使用Azure Web作业配置应用程序洞察

Posted 2023-02-25

我正在尝试为我的webjob配置Application Insights（Microsoft.Azure.Webjobs（v：2.3）

if (!string.IsNullOrEmpty(instrumentationKey))

    // Wire up with default filters; Filtering will be explained later.
    config.LoggerFactory = new LoggerFactory()
                .AddApplicationInsights(instrumentationKey, null)
                .AddConsole();

    config.Tracing.ConsoleLevel = TraceLevel.Off;

loggerFactory不可用。

我已经安装了以下这些包。

<package id="Microsoft.ApplicationInsights" version="2.4.0" targetFramework="net471" />
<package id="Microsoft.ApplicationInsights.Agent.Intercept" version="2.4.0" targetFramework="net471" />
<package id="Microsoft.ApplicationInsights.DependencyCollector" version="2.4.1" targetFramework="net471" />
<package id="Microsoft.ApplicationInsights.PerfCounterCollector" version="2.4.1" targetFramework="net471" />
<package id="Microsoft.ApplicationInsights.WindowsServer" version="2.4.1" targetFramework="net471" />
<package id="Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel" version="2.4.0" targetFramework="net471" />
<package id="Microsoft.Azure.WebJobs.Logging" version="3.0.6" targetFramework="net471" />
<package id="Microsoft.Azure.WebJobs.Logging.ApplicationInsights" version="2.3.0" targetFramework="net471" />

谢谢！

答案

您已安装以下NuGet包：

• Microsoft.Azure.WebJobs.Logging.ApplicationInsights
• Microsoft.Extensions.Logging
• Microsoft.Extensions.Logging.Console

看看here。

另一答案

似乎JobHostConfiguration缺少var config = new JobHostConfiguration();

否则，您可以像下面的代码段一样进行配置

var builder = new HostBuilder().ConfigureLogging((context, b) =>

    b.AddConsole();

    // If the key exists in settings, use it to enable Application Insights.
    var instrumentationKey = context.Configuration["APPINSIGHTS_INSTRUMENTATIONKEY"];
    if (!string.IsNullOrEmpty(instrumentationKey))
    
        b.AddApplicationInsights(o => o.InstrumentationKey = instrumentationKey);
    
)
