Hi Tejaswi,
Thank you for reaching out and sharing your question on the Q&A portal. I appreciate the details you provided about the issue with the Azure VM agent status changing to "not ready" and the impact on VM availability for users.
To troubleshoot the Azure VM agent status, you can start by checking the agent logs located in the C:\WindowsAzure\Logs\WaAppAgent.log directory on the affected VM. This log often provides insights into why the agent might be failing. Additionally, verifying network connectivity between the VM and Azure services is crucial, as interruptions can cause the agent to go into a "not ready" state.
Another helpful step is to ensure the VM agent is up to date. You can manually update it by downloading the latest version from the Azure portal or redeploying the VM, which often resolves underlying agent issues.
For more detailed guidance, I recommend reviewing these Microsoft articles:
