Question

What is the reason for Azure virtual machine agent status not ready error?

Shreya Sanghavi 1

Hi,
I have a VM of type Standard D4s v3 (4 vcpus, 16 GiB memory) running in azure with Linux (centos 8.2.2004) operating system. It is my development instance that is running 24 * 7. But the problem is randomly my site is unreachable and when I check the portal I am seeing the following error
"azure vm agent status not ready"

The instance is not accessible with SSH as well. The only solution is to restart the machine and start all our services again. That is not an ideal solution. Why this behaviour? can somebody help me with this?

Hello @Shreya Sanghavi ,

Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

The most common reasons for guest agent status to go "Not ready" are:

The Linux VM guest agent(WALA) is out of the date/corrupted
Guest agent is not communicate with WireServer IP (Host IP).

We have a detailed troubleshooting guide for this issue which covers both the above cases https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/linux-azure-guest-agent

Hope this helps.

Thank you @Prrudram-MSFT for response.

I have gone through many azure-guest-agent documents including the one you have provided. But to perform the checks as shown in the document, I need to connect to VM using SSH. But I am not able to connect with VM after this error so could not follow that guide.

@Shreya Sanghavi ,

In most cases, you will see these 2 issues in parallel. First you need to fix the SSH connection problem. You can follow the guidance provided in this TSG here https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/troubleshoot-ssh-connection
Once the SSH issue is resolved. You can try fixing the agent issue.

If you already have tried the steps to fix SSH and still no go, then this issue needs deeper investigation. Azure technical support team will be able to check and help on this. I would recommend you to open an azure support case. If you don't have the ability to open a technical support ticket, please let me know I can help you further on this.
