Description

The following Application Insights tabs in Azure Portal might show no data: Overview, Application map, Failures, or Performance. The root cause of the issue is that the Application Insights metrics such as Requests and Performance Counters are not collected.

Solution

To resolve the issue, consider one of the following options:

• Upgrade Sitecore XP instance to Sitecore XP 9.2 or later.
• Proceed as follows:
  
  1. Download and install the hotfix compatible with the affected product version (carefully follow all the instructions from the readme.txt file):
     
     • For Sitecore XP 9.1.1: SC Hotfix 486708-1.zip
     • For Sitecore XP 9.1.0: SC Hotfix-313501-1 Application Insights 4.1.0.zip

     Be aware that the hotfixes were built for specific Sitecore XP versions, and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XP instance, send a request for a compatibility check to Sitecore Support.

     Note that the ZIP file contents must be extracted to locate installation instructions and related files inside. The hotfixes must be installed on a CM instance and then synced with other instances using standard development practices.

  2. Restart the Azure App Service instance.
