Operation name not being sent to Application Insights.

[claudiopi]

Hi,

I am trying to use Serilog to centralize logging exceptions and for Application Insights I would like to use this project.

Although the exception does get logged in Application Insights it lacks the parent operation name

I attach here a project that demostrates the issue using both Microsoft.ApplicationInsights.AspNetCore and Serilog.Sinks.ApplicationInsights

When using Microsoft.ApplicationInsights.AspNetCore I correctly get the parent operation:

When using Serilog.Sinks.ApplicationInsights I only get the exception, but no parent operation:

To test, just replace in both application insights your instrumitation key / connection string, and then run the appropiate configuration

Thanks!

So analyzing the network call, I realized that ai.operation.name is not being sent to AI

when using Microsoft.ApplicationInsights.AspNetCore the following is being posted:

    "ai.application.ver": "1.0.0.0",
    "ai.cloud.roleInstance": "PC-MVD",
    "ai.operation.id": "540951cacb4095d87f89e8c00e62e3f1",
    "ai.operation.parentId": "ce1f02a301d748f7",
    "ai.operation.name": "GET Demo/TestExceptionLogging",
    "ai.location.ip": "::1",
    "ai.internal.sdkVersion": "il:2.22.0-997",
    "ai.internal.nodeName": "PC-MVD"

when using Serilog.Sinks.ApplicationInsights the following is being posted (which misses among other things the operation name):

   "ai.cloud.roleInstance": "PC-MVD",
    "ai.operation.id": "540951cacb4095d87f89e8c00e62e3f1",
    "ai.operation.parentId": "ce1f02a301d748f7",
    "ai.internal.sdkVersion": "dotnetc:2.22.0-997"

Hi, this issue is causing the azure function console to not display any logs beside executing / executed one

I've found a workaround until this issue is officially fixed

I've created a custom Trace converter that is adding the operation_Namevalue. Also note the true values when calling the base.FowardPropertiesToTelemetryProperties. The most important is the value of includeLogLevel without it "LogLevel" do not display in the azure invocation screen

public class MyTelemetryTraceConverter : TraceTelemetryConverter
{
    public override void ForwardPropertiesToTelemetryProperties(LogEvent logEvent, ISupportProperties telemetryProperties, IFormatProvider formatProvider)
    {
        base.ForwardPropertiesToTelemetryProperties(logEvent, telemetryProperties, formatProvider, true, true, true);
        if (telemetryProperties is ITelemetry telemetry 
            && string.IsNullOrWhiteSpace(telemetry.Context.Operation.Name)
            && logEvent.Properties.TryGetValue("AzureFunctions_FunctionName", out LogEventPropertyValue value))
        {
            telemetry.Context.Operation.Name = value.ToString().Trim('"');
        }
    }
}
