Azure Application Insights not working on Sitecore 9.1 PaaS

Question

I've provisioned a Sitecore 9.1 PaaS, and for some odd reason the Application Insights is not loading graphics except in Live Metrics Stream for Process CPU data

I went through the existing post Accessing log files in application insights for Sitecore 9 in Azure app service and did the following

1. Check appinsights.instrumentationkey ConnectionStrings.config

2. Check the Daily Cap It was 0.33, then I raised to 2GB for testing purposes

Another thing is that the Search shows results from Sitecore

3. Check showconfig.aspx

4. Enable Live Metrics Stream - Only shows CPU data

5. Enable Application map - I removed the comment line, and restart the Application, waited for 5 minutes and still no data

6. Querying Application Insights - It works

Answer 1

This is also a bug in Sitecore 9.1 update 1. I have raised it as a ticket with Sitecore support and they have provided a bug reference 291373. Development of the hotfix is in progress.

I note that in the hotfix mentioned above, 2 of the files are not present in the /bin folder of 9.1.1. The missing files are:

• /bin/Microsoft.AspNet.TelemetryCorrelation.dll
• /bin/System.Diagnostics.DiagnosticSource.dll

Answer 2

We have raise this problem to the Sitecore Support which generated a ticket #527731 (Please use this ticket# if you have the same issue)

IMPORTANT: The following approach does not work without the hotfix provided by Sitecore, don't give a shot by simply changing the files specified in the step"after the hotfix has been installed"

Accordingly to the Sitecore response

Be aware that the hotfix was built specifically for Sitecore XP 9.1 Initial Release, and you should not install it on other Sitecore versions or in combination with other hotfixes, unless explicitly instructed by Sitecore Support.

Note that you need to extract ZIP file contents to locate installation instructions and related files inside it.

Unless stated differently in the installation instructions, the hotfix should be installed on CM instance and then synced with other instances using your regular development practices

The hotfix should be installed as a package, and will replace the following DLL libraries:

• /bin/Microsoft.AI.Web.dll

• /bin/Microsoft.ApplicationInsights.dll

• /bin/Microsoft.ApplicationInsights.TraceListener.dll

• /bin/Microsoft.AspNet.TelemetryCorrelation.dll

• /bin/System.Diagnostics.DiagnosticSource.dll

After the hotfix has been installed these steps must be taken

1. Edit ApplicationInsights.config. Under the ApplicationInsights\TelemetryModules paste the following line at the bottom of the section

   <Add Type="Microsoft.ApplicationInsights.Web.AspNetDiagnosticTelemetryModule, Microsoft.AI.Web" />

   2. Edit web.config. Under the configuration/system.webServer/modules after <remove name="ApplicationInsightsWebTracking"/>, insert the following string:

<add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" preCondition="integratedMode,managedHandler"/>

Once you modify the files, restart the App Services and try to access it again to generate data for the Application Insights

Answer 3

It's a bug in 9.1.

To fix this you need:

Add telemetry module to ApplicationInsights.config

<Add Type="Microsoft.ApplicationInsights.Web.AspNetDiagnosticTelemetryModule, Microsoft.AI.Web"/>

Add module to web.config under system.webserver

<add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" 
        preCondition="integratedMode,managedHandler" />
