Hi support,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
Let me help you with the steps
1.Check Log Analytics Workspace Connection: Make sure your VM is connected to the correct Log Analytics Workspace. Run this command to check
az vm extension show --resource-group <your-resource-group> --vm-name <your-vm-name> --name AzureMonitorLinuxAgent --query 'Settings.workspaceId'
2. Verify DCR Configuration: Ensure that the Data Collection Rule (DCR) is applied to the VM and set to send heartbeat data. In the Azure portal, go to Monitor > Data Collection Rules and check if the VM is listed under the DCR's scope.

3.Check Agent Logs: Look for any errors in the Azure Monitor Agent (AMA) logs on the VM. Logs can be found here:

Windows: C:\ProgramData\AzureMonitorAgent\Log

Linux: /var/opt/microsoft/azuremonitoragent/log

4. Check Time Synchronization: Ensure your VM’s time is synced properly, as incorrect time settings can prevent the heartbeat from being sent.
   5.Once Re-install and Install AMA.
