 To remove always ready instances, use the [`az functionapp scale config always-ready delete`](/cli/azure/functionapp/scale/config/always-ready#az-functionapp-scale-config-always-ready-delete) command, as in this example that removes all always ready instances from both the HTTP triggers group and also a function named `hello_world`:
 
 ```azurecli
-az functionapp scale config always-ready delete --resource-group <RESOURCE_GROUP> --name <APP_NAME> --setting-names http hello_world
+az functionapp scale config always-ready delete --resource-group <RESOURCE_GROUP> --name <APP_NAME> --setting-names http function:hello_world
 ```
