Question

我正在使用Openstack Mitaka。在Django，我想为租户提供所有资源。（还行吧）之后我需要了解资源类型。例如，如果它是实例或浮动IP等，

def sync_resources():
    logger.info("Executing sync_resources")
    sync_tenants()
    tenants = Tenant.objects.all()
    managers = Manager.objects.filter(is_active=True)
    for manager in managers:
        services = manager.services.all()
        regions = manager.region_set.all()
        for region in regions:
            ceilometer_driver = CeilometerDriver(region_name=region.name, **manager.ceilometer_params)
            if ceilometer_driver.is_authenticated:
                for tenant in tenants:
                    queries = [ceilometer_driver.make_query("project_id", ceilometer_driver.EQUAL, tenant.tenant_id)]
                    resource_list = ceilometer_driver.get_resource_list(query=queries)

在此代码中，我获得了租户的所有资源。但是我不需要所有这些。我会根据类型列表过滤它们。例如＆＃34;实例，floating_ip，卷，快照等＆＃34;

以下是资源详细信息示例： sample resource floating_ip

从元数据

我可以看到它是一个floating_ip。但是我在细节中看不到它的类型浮动ip。元数据会针对不同类型的资源进行更改。

我还从终端检查了

$ ceilometer resource-list
$ ceilometer resource-show id-of-resource

再一次，细节没有帮助。

所以我需要一种方法来轻松理解资源类型并将它们与＆＃34;实例，浮动ip，卷，快照等匹配。＆＃34;

其他信息：

经过一番研究后，我意识到我可以从链接信息中获取类型。这不适用于＆＃34; ceilometerclient＆＃34;我在ceilometer_driver中使用。当我直接从REST API调用时，我可以获得额外的链接信息。

以下是调用单个项目资源的URL：

http://192.168.101.11:8777/v2/resources?q.field=project_id&q.value=63c40f56e11a4d24981710fd46285233

以下结果是一个例子。我删除了大部分链接。但是一个链接显示它是一个实例。

这是浮动ip的另一个：

"user_id": null,

    {
        "href": "http://192.168.101.11:8777/v2/resources/f61e437d-dce3-4562-bd48-e14a6f0604f3",

        "rel": "ip.floating"
    },
    {
        "href": "http://192.168.101.11:8777/v2/meters/ip.floating.create?q.field=resource_id&q.value=f61e437d-dce3-4562-bd48-e14a6f0604f3",
        "rel": "ip.floating.create"
    }
],

    "floating_ip_address": "192.168.103.132",
    "port_id": "None"
    }
}

所以实例有一个链接＆＃34; rel＆＃34;：＆＃34;实例＆＃34; 并且浮动的ip有一个链接＆＃34; rel＆＃34;：＆＃34; ip.floating＆＃34;

我想我可以通过REST API调用而不是使用驱动程序对它们进行排序。然而，这种所谓的解决方案在我看来并不是正确的方法。所以我仍然在寻找更好的方法。欢迎所有答案和意见。
