AMA extension installation to Arc enabled VM fails

Question

We are currently trying to install AMA extension through the Monitor DCR. Data collection rule is created fine, we can see the extensions are in "creating" status when we view Azure Arc VM overview page. But it gets stuck in creating status for hours then just disappears. Checking the local VM logs, I have found the following:

However, we are not seeing any connection failures on our proxy / firewalls. Anyone had any similar issues? I would like to point out that these VMs are running on Connected Machine Agent version 1.21, as pervious version had an issue with extension installation, but shouldn't be a problem with version 1.21

Answer 1

Are these Azure VM's? Asking because Arc is only for non-Azure systems. I assume these are on-prem VMs...I didn't think it was possible to put Arc on an Azure VM but just checking.

I would check the application event log for any related events. Maybe try manually deploying a different extension just to see if it is Arc or the extension. Reinstall Arc, reboot, check the Arc troubleshooting doc. https://learn.microsoft.com/en-us/azure/azure-arc/servers/troubleshoot-agent-onboard

Answer 2

@Sadik Karadag Thanks for reaching out. I understand that you are trying to install Azure Monitor Agent on an Azure Arc enabled VM. However, you are seeing an issue with the installation process; It keeps stuck at 'creating' and it doesn't complete the process.

I would suggest you upgrade Connected Machine Agent to latest Version 1.22 and follow the steps mentioned here to troubleshoot the issue and raise support ticket accordingly.

Answer 3

Did you ever find the cause of this?

Having the same issue as you describe except i'm using AZCMagent v1.22
