Application Insights not tracking sql queries

Question

I'm trying to configure my own environment to send data to App Insight with Status Monitor and works fine except sql queries.

I have one environment on Azure VM with Azure Database and the SQL queries are been tracking well, but in my own VM against my own Databases not working.

The sql trace recorded on that environment is like that: "mssql-IP | database-name" instead of query content.

The application tested in both environment is the same, the SO version is the same.

I tryed configure my environment against Azure Databases, but still the same problem.

I installed .NET 4.6 and still the same problem.

Answer 1

NEW METHOD (Status Monitor v2 - PowerShell)

See these instructions for enabling the instrumentation engine.

OLD METHOD (Status Monitor v1)

After reviewing every scrap of documentation, GitHub issue, and blog post I could find on this problem, I believe I have the definitive answer for an IIS environment:

1. Status Monitor needs to be installed to collect dependency details. This configures the necessary .NET profiler. Even if you have Application Insights configured at build time (i.e. not having Status Monitor configure Application Insights for you at runtime) and are using .NET 4.6+, Status Monitor still needs to be present. (In my opinion, the Microsoft documentation does not make this clear.)

2. Correct permissions:

   CMD

   icacls %WINDIR%\Temp /t /c /grant IIS_IUSRS:(OI)(CI)M
   icacls %WINDIR%\System32\config\systemprofile\AppData\Local /t /c /grant IIS_IUSRS:(OI)(CI)M
   

   or

   PowerShell

   icacls $env:WINDIR\Temp /t /c /grant IIS_IUSRS:'(OI)(CI)M'
   icacls $env:WINDIR\System32\config\systemprofile\AppData\Local /t /c /grant IIS_IUSRS:'(OI)(CI)M'
   

3. Correct IIS service environment variables:

   Get-Item 'HKLM:\SYSTEM\CurrentControlSet\Services\W3SVC' | Remove-ItemProperty -Name Environment -ErrorAction SilentlyContinue
   Get-Item 'HKLM:\SYSTEM\CurrentControlSet\Services\W3SVC' | New-ItemProperty -Name Environment -Value "COR_ENABLE_PROFILING=1","COR_PROFILER={324F817A-7420-4E6D-B3C1-143FBED6D855}","MicrosoftInstrumentationEngine_Host={CA487940-57D2-10BF-11B2-A3AD5A13CBC0}" -PropertyType MultiString
   

4. Restart IIS:

   iisreset
   

Answer 2

You should verify Status Monitor-collected data is making its way to Application Insights.

In Analytics try the query:

dependencies | where timestamp > ago(1d) | summarize count() by cloud_RoleInstance, sdkVersion

If you see sdkVersion results prefixed with rddf instead of rddp, the SDK is sending data without the enhancements from Status Monitor (like SQL query content). If this is the case, check your installation of Status Monitor to ensure it's active for your application.

Answer 3

I finally solved this problem.

I grant modify access to IIS_IUSRS group for these paths:

• %WINDIR%\Temp
• %WINDIR%\System32\config\systemprofile\AppData\Local

Then, Application Insights started to record SQL queries.

You also can do this via the command line:

• icacls %WINDIR%\Temp /t /c /grant IIS_IUSRS:(OI)(CI)M
• icacls %WINDIR%\System32\config\systemprofile\AppData\Local /t /c /grant IIS_IUSRS:(OI)(CI)M
