-To discover the codes for other test locations, or to automate the creation of more complex web tests, create an example manually and then parameterize the code from [Azure Resource Manager](https://resources.azure.com/).
+To automate availability tests consult the [metric alerts template article](https://docs.microsoft.com/azure/azure-monitor/platform/alerts-metric-create-templates#template-for-a-availability-test-along-with-availability-test-alert).
