Operazione per recuperare gli URI di firma di accesso condiviso dei log di diagnostica di avvio per una macchina virtuale in un set di scalabilità di macchine virtuali.

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}/virtualMachines/{instanceId}/retrieveBootDiagnosticsData?api-version=2025-04-01

Con parametri facoltativi:

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}/virtualMachines/{instanceId}/retrieveBootDiagnosticsData?api-version=2025-04-01&sasUriExpirationTimeInMinutes={sasUriExpirationTimeInMinutes}

Parametri dell'URI

Nome	In	Necessario	Tipo	Descrizione
instanceId	path	True	string	ID istanza della macchina virtuale.
resourceGroupName	path	True	string minLength: 1 maxLength: 90	Nome del gruppo di risorse. Il nome è insensibile alle maiuscole e minuscole.
subscriptionId	path	True	string minLength: 1	ID della sottoscrizione di destinazione.
vmScaleSetName	path	True	string	Nome del set di scalabilità di macchine virtuali.
api-version	query	True	string minLength: 1	Versione dell'API da usare per questa operazione.
