How can I get information on my template failing to start?

Question

I'm using Azure Labs Services (for classrooms), and I can't start my Template VM. The "start VM" trigger will work, but the VM will fail to start and return to a "stopped" state without any error message in the Labs environment or the Azure Portal. Is there a way I can pull more debugging information as to why my Template didn't start, or a possible troubleshooting option from someone who's experienced this problem before?

Answer 1

Yes of course, you can troubleshoot it further by checking the Activity logs of your Lab account from within the Azure portal as follows:

Expanding the failed event further, you should be able to see the Error code and the Message. Switching to the JSON representation, look for the statusMessage key within properties that has more details.

For example:

..
"properties": {
    "statusMessage": "{\"status\":\"Failed\",\"error\":{\"code\":\"ResourceOperationFailure\",\"message\":\"The resource operation completed with terminal provisioning state 'Failed'.\",\"details\":[{\"code\":\"ResourceGroupNotFound\",\"message\":\"Resource group 'MX-RG-xxxxx' could not be found.\"}]}}"
},
..

This should hopefully give you enough information to take the next steps.

There's an ongoing outage for Azure Lab Services. Please follow updates here.
