我正在尝试从VMware ESXi服务器中的DataStores获取典型属性(容量,可用空间,名称)。我无法获得TraversalSpec,ObjectSpec和PropertySpecs。
有人可以告诉我我做错了吗?
public void GetDataStoreValues()
{
PropertyFilterSpec spec = GetDataStoreQuery();
ObjectContent[] objectContent = _service.RetrieveProperties(_sic.propertyCollector, new[] { spec } );
foreach (ObjectContent content in objectContent)
{
if (content.obj.type == "DataStore")
{
//... get values
}
}
}
private PropertyFilterSpec GetDataStoreQuery()
{
try
{
// Traversal to get to the host from ComputeResource
TraversalSpec tSpec = new TraversalSpec
{
name = "HStoDS",
type = "HostSystem",
path = "dataStore",
skip = false
};
// Now create Object Spec
var objectSpec = new ObjectSpec
{
obj = _sic.rootFolder,
skip = true,
selectSet = new SelectionSpec[] { tSpec }
};
var objectSpecs = new[] { objectSpec };
// Create PropertyFilterSpec using the PropertySpec and ObjectPec
// created above.
// Create Property Spec
string[] propertyArray = new[] {
"summary.capacity"
,"summary.freeSpace"
,"summary.name"
};
var propertySpec = new PropertySpec
{
all = true,
pathSet = propertyArray,
type = "DataStore"
};
var propertySpecs = new[] { propertySpec };
var propertyFilterSpec = new PropertyFilterSpec
{
propSet = propertySpecs,
objectSet = objectSpecs
};
return propertyFilterSpec;
}
catch (Exception)
{
}
return null;
}
此外,对象类型名称是否区分大小写?当我看样品时,我似乎看到了各种各样的情况。
感谢您的任何建议。

第一个问题:您可以使用以下代码获取DataStore的属性。我在vCenter 5.1上测试了这段代码
public void Test()
{
var properties = GetProperties(
new ManagedObjectReference { type = "Datastore", Value = "<your_datastore_key>" },
new[] {"summary.capacity", "summary.freeSpace", "summary.name"});
}
private List<DynamicProperty> GetProperties(ManagedObjectReference objectRef, string[] properties)
{
var typesAndProperties = new Dictionary<string, string[]> { { objectRef.type, properties } };
var objectContents = RetrieveResults(typesAndProperties, new List<ManagedObjectReference> { objectRef });
return ExtractDynamicProperties(objectRef, objectContents);
}
private List<ObjectContent> RetrieveResults(Dictionary<string, string[]> typesAndProperties, List<ManagedObjectReference> objectReferences)
{
var result = new List<ObjectContent>();
var tSpec = new TraversalSpec { path = "view", skip = false };
var oSpec = new ObjectSpec { skip = true, selectSet = new SelectionSpec[] { tSpec } };
oSpec.obj = service.CreateListView(serviceContent.viewManager, objectReferences.ToArray());
tSpec.type = "ListView";
var fSpec = new PropertyFilterSpec
{
objectSet = new[] { oSpec },
propSet = typesAndProperties.Keys.Select(typeName => new PropertySpec { type = typeName, pathSet = typesAndProperties[typeName] }).ToArray()
};
PropertyFilterSpec[] pfs = { fSpec };
var retrieveResult = service.RetrievePropertiesEx(serviceContent.propertyCollector, pfs, new RetrieveOptions());
if (retrieveResult != null)
{
result.AddRange(retrieveResult.objects);
while (!String.IsNullOrEmpty(retrieveResult.token))
{
retrieveResult = service.ContinueRetrievePropertiesEx(serviceContent.propertyCollector, retrieveResult.token);
result.AddRange(retrieveResult.objects);
}
service.DestroyView(oSpec.obj);
}
return result;
}
private static List<DynamicProperty> ExtractDynamicProperties(ManagedObjectReference objectRef, IEnumerable<ObjectContent> objectContents)
{
var result = new List<DynamicProperty>();
foreach (var objectContent in objectContents)
{
if (objectContent.propSet == null) continue;
if (objectContent.obj == null) continue;
if (objectContent.obj.type != objectRef.type || objectContent.obj.Value != objectRef.Value) continue;
result.AddRange(objectContent.propSet);
}
return result;
}
如何运行示例:
service
类的对象初始化VimService
,按serviceContent
类的对象初始化ServiceContent
。service
登录vCenter或ESX。<your_datastore_key>
替换为您的数据存储区的密钥。您可以使用Managed Object Browser查找其数据存储区的密钥。要获取数据存储区对象的描述,请转到MOB中的以下链接:content - &gt; rootFolder - &gt; childEntity - &gt; datastoreFolder - &gt; childEntity。页面顶部的“托管对象ID”值是正确的密钥(如datastore-46
)。第二个问题:是的,ManagedObjectReference的类型区分大小写。
