SL 中自动缩放的详细信息

Question

我正在使用 Java API 实现自动缩放的详细信息。如何获取会员配置的详细信息。请参考附图中红框内的字段。我可以获得详细信息。例如，我可以得到操作参考代码，它是CENTOS_6_64，但是我如何得到像CentOS 6.x - Minimal Install (64bit) 这样的长类型描述。

Answer 1

尝试使用此对象遮罩

mask[id, name, status[name, keyName], regionalGroup[id, name, description], suspendedFlag, terminationPolicy, cooldown, regionalGroupId, minimumMemberCount, maximumMemberCount, balancedTerminationFlag, networkVlans[ id, networkVlan[ id, name, vlanNumber, networkSpace, primaryRouter[id,hostname,datacenter[name,longName]],localDiskStorageCapabilityFlag,sanStorageCapabilityFlag]],virtualGuestMemberTemplate[hostname,domain,fullyQualifiedDomainName,startCpus,maxMemory,hourlyBillingFlag,localDiskFlag,operatingSystem,datacenter,privateNetworkOnlyFlag,networkComponents.maxSpeed,sshKeys,operatingSystemReferenceCode,blockDevices[device,diskImage.capacity],blockDeviceTemplateGroup.globalIdentifier,postInstallScriptUri],policies[id,cooldown,name,scaleActions[id,type[id,keyName,name],amount,scaleType],triggers[id,type],triggers(SoftLayer_Scale_Policy_Trigger_OneTime)[date],triggers(SoftLayer_Scale_Policy_Trigger_Repeating)[schedule],triggers(SoftLayer_Scale_Policy_Trigger_ResourceUse)[watches[id,algorithm,metric,operator,period,value]]],loadBalancers[id,port,healthCheck[id,attributes[value,type.keyname],type[id,keyname,name]],virtualServer[id,port,virtualIpAddress.ipAddress.ipAddress,virtualIpAddress.id,serviceGroups.routingType.name]],virtualGuestMemberCount]

这里是一个使用 python 的例子：

但如果你尝试复制与传送门相同的信息，你真的会玩得很开心:)。

关于OS无法通过SoftLayer_Scale_Group服务获取信息，需要使用SoftLayer_Virtual_Guest::getCreateObjectOptions方法。如果您看到该方法的结果，您将看到：

{
            "itemPrice": {
                "hourlyRecurringFee": "0",
                "recurringFee": "0",
                "item": {
                    "description": "CentOS 6.x - Minimal Install (64 bit)"
                }
            },
            "template": {
                "id": null,
                "operatingSystemReferenceCode": "CENTOS_6_64"
            }
        }

正如你所看到的结果包含 "operatingSystemReferenceCode" 和你想要的描述，所以只需要查找与你使用 "operatingSystemReferenceCode" 值匹配的记录 SoftLayer_Scale_Group::getObject方法。

关于网络私有或者public，这里只能有以下场景： 1.- public 并且已设置私有。 2.- 只设置了私有。

确定您必须检查"privateNetworkOnlyFlag" 属性： 1.- 如果属性为真，网络是私有的 2.- 如果未设置属性（默认值为 false），则网络为 public 且私有。

为了获得与门户相同的描述，您需要使用 SoftLayer_Virtual_Guest::getCreateObjectOptions 方法，这是您获得的结果：

"networkComponents": [
        {
            "itemPrice": {
                "hourlyRecurringFee": "0",
                "recurringFee": "0",
                "item": {
                    "description": "10 Mbps Public & Private Network Uplinks"
                }
            },
            "template": {
                "id": null,
                "networkComponents": [
                    {
                        "maxSpeed": 10
                    }
                ],
                "privateNetworkOnlyFlag": false
            }
        }

如您所见，这个想法与操作系统相同。

关于数据中心 "First Available"，我猜当你调用 SoftLayer_Scale_Group::getObject 我猜 virtualGuestMemberTemplate.datacenter 属性是空的或不存在，如果你看到您可以将值显示为 "First Available".

此致

Answer 2

这是获取网络标志的测试代码。标志 returns "true"，但门户显示 "Public & Private Network"。

private void getPrivateNetwork() {

    Group.Service groupSrv = Group.service(client, 1046365L);
    groupSrv.withMask().virtualGuestMemberTemplate().privateNetworkOnlyFlag();

    Group result = groupSrv.getObject();
    System.out.println(
            "private Network flag : " + result.getVirtualGuestMemberTemplate().getPrivateNetworkOnlyFlag());

}
