Hi, sometimes I see that Windows Azure Guest Agent Service has went to disabled state which cause few issues like backup failing. What, how or where is best place to investigate issue? Does Windows Azure Guest Agent generate logs and if yes, we can I find it? Agent has been installed by .msi file (migrated machine) if it has anything to do with this issue.

Hi @Bombbe - It's possible that the Guest Agent may be outdated, running into errors, or is being force Disabled by other services. You'll want to make sure that Auto-Update is enabled in the config. You can also manually reinstall the Agent if needed. Common troubleshooting steps can be located here: https://learn.microsoft.com/en-us/azure/virtual-machines/troubleshooting/windows-azure-guest-agent Starting point should be to review the Logs. The Windows Guest Agent Logs can also be located here by default: C:\WindowsAzure\Logs\WaAppAgent.log C:\WindowsAzure\Logs\TransparentInstaller.log

Hi,
is is possible to enable Auto-Update if Guest Agent has been installed manually with .msi or is that feature only available if vm has been made with marketplace image?

I will check out those logs, but do you know what is difference between TransparentInstaller.log and WaAppAgent.log?

Manual install, or pre-installed should be the same. The Auto-Update Feature for the Windows Guest Agent should actually be automatic now. Previous versions, and Linux can be manually set. If the Auto-Update doesn't work, then make sure the Guest Agent is updated, or clean reinstalled.

The WaAppAgent.log shows Informational and Error logging for the Azure Guest Agent. TransparentInstaller.log shows historical monitor and health data.

Thank you for the answers. Last question, do you know how agent update if vm has not internet access? Like using Azure ip-addresses 168.63.129.16?

Exactly, the 'WireServer' is 168.63.129.16, and just needs to be open in the Firewall in the VM. This goes for a lot of other VM to Host communications like DNS. https://learn.microsoft.com/en-us/azure/virtual-network/what-is-ip-address-168-63-129-16
