Root cause of the Issue

This error is thrown when the ASP.NET is not installed as part of the IIS (WebServer).

Steps to Install ASP.NET

1. Select the IIS server
2. Click on Manage
3. Select Add Server Role
4. Below is the image to show the ASP.NET installation.

Post Installation

Once the ASP.NET version is installed properly the Element not Found Error will be gone automatically and you can verify the data.

1. Error disappears after installing the ASP.NET

2. net_clr data is processed and ingested into Elastic.

Next Steps

• Update document with ASP.NET installation link. This would help to get a view of what needs to be installed as a part of the IIS Setup.
• Include the Element not Found Error issue in innovations hub.
• Instrument to identify whether the data is getting ingested with the process metrics alone if the .netclr exception is thrown.
