2 WBEM Overview Web-Based Enterprise Management (WBEM) is a platform and resource independent DMTF standard that defines both a common model (i.e., description) and protocol (i.e., interface) for monitoring and controlling resources from diverse sources (e.g., different types of platforms or different types of resources on the same platform). How many processes are running on syste m1? How may users are logged on to syste m2? Ho w many processors are available on system3? system1 CIM Operations system2 System Administrator system3 Page 2

3 WBEM WBEM is defined by a set of standards that include: A Data Description: A description of management data that is not bound to a particular implementation. The CIM data description includes (1) the description of a meta-language for describing data (CIM Specification) and (2) a description of managed resources (DMTF CIM Schema + vendor extensions). An Encoding: A standard for encoding CIM data and operations. A Transport Protocol: The definition of a protocol for transporting CIM encoded requests and responses. Encoding Data Description CIM Specification CIM Schema Transport Specifications and Schema are available at: Page 3

4 CIM-XML WBEM Standard WBEM is defined by a set of standards that include: June San Jose, California A Data Description: A description of management data that is not bound to a particular implementation. The CIM data description includes (1) the description of a meta-language for describing data (CIM Specification) and (2) a description of managed resources (DMTF CIM Schema + vendor extensions). A CIM-XML Encoding: A standard for encoding CIM data and operations into XML. An HTTP Transport Protocol: The definition of a standard protocol for transporting CIM-XML encoded requests and responses over HTTP. CIM-XML Encoding Data Description CIM Specification CIM Schema Access HTTP Transport Specifications and Schema are available at: Page 4

5 CIM Data Model A CIM Schema contains a formal description of data, and actions on data, that is of interest to management applications. Oh Isee Nu mberofprocess is a Property of the class CI M_ OperatingSystem. Using CIM, WBEM provides a platform and resource neutral mechanism for management applications to describe a request to access a managed resource. CIM_ComputerSystem CIM_RunningOS CIM_OperatingSystem CreationClassName: string [key] Name: string [key] OSType: uint16 OtherTypeDescription: string Version: string LastBootUpTime: datetime LocalDateTime: datetime CurrentTimeZone: sint16 NumberOfLicensedUsers: uint32 NumberOfUsers: uint32 NumberOfProcesses: uint32 MaxNumberOfProcesses: uint32 TotalSwapSpaceSize: uint64 TotalVirtualMemorySize: uint64 FreeVirtualMemory: unit64 FreePhysicalMemory: uint64 TotalVisibleMemorySize: uint64 SizeStoredInPagingFiles: uint64 FreeSpaceInPagingFiles: uint64 MaxProcessMemorySize: uint64 Distributed: boolean MaxProcessesPerUser: uint32 Reboot(): uint32 Shutdown(): uint32 Page 5

6 Terminology A CIM Operation describes a management action (i.e., a monitor or control request) on a CIM modeled resource. A CIM Client sends CIM Operation requests and receives CIM Operation responses. CIM Client CIM Operation CIM Server A CIM Server receives CIM Operation requests and sends CIM Operation responses. System Administrator CIM Server CIM s CIM Server CIM s CIM Server CIM s A CIM Client can be used to monitor and control local and/or remote resources. CIM Client CIM Operations CIM Server CIM s CIM Server CIM s CIM Server CIM s Page 6

7 Terminology CIM Client CIM Server CIM s Managed CIM Client. Management application capable of (1) sending CIM Operation requests and (2) receiving CIM Operation responses. CIM Server. Management infrastructure capable of (1) receiving CIM Operation requests, (2) coordinating the processing of requests and responses among the CIM s and (3) sending CIM Operation responses. CIM. Management instrumentation capable of (1) translating CIM formatted requests into resource-specific operations and (2) translating resource-specific responses into CIM formatted responses. Managed Resource. A manageable entity (e.g., disk, process, system, application, network) plus the resource-specific instrumentation required to manage and control the entity. Page 7

8 CIM Operation Overview June San Jose, California The DMTF has defined a set of CIM Operations. Functional Group Basic read Basic Write Schema Manipulation Instance Manipulation Association Traversal Query Qualifier Declaration GetClass, EnumerateClasses, EnumerateClassNames, GetInstance, EnumerateInstances, EnumerateInstanceNames, GetProperty SetProperty CreateClass, ModifyClass, DeleteClass CreateInstance, ModifyInstance, DeleteInstance Associators, AssociatorNames, References, ReferenceNames ExecQuery Methods GetQualifier, SetQualifier, DeleteQualifier, EnumerateQualifier CIM Client A CIM Operation describes a management (i.e., monitor or control) action on a CIM modeled resource. CIM Server Page 8

9 CIM Operation Example June San Jose, California Ok, I'm interested How would I use WBEM to find how many processes are running on system1? system1 CIM Operations system2 System Administrator system3 Page 9

10 GetProperty Example The GetProperty operation can be used to retrieve a single property value from a CIM Instance in the target Namespace. GetProperty <propertyvalue> GetProperty ( [IN] <instancename> InstanceName, [IN] <string> PropertyName ) I understand that (1) the value of PropertyName will be "NumberOfProcesses" and (2) the actual value will be returned as a 32-bit unsigned integer But what is InstanceName? And what's a Namespace? M O F Frag ment Describing Nu mberofprocesses Property [Description ( "Number of process contexts currently loaded or " "running on the OperatingSystem."), Gauge, MappingStrings {"MIF.DMTF Host System 001.5", "MIB.IETF HOST-RESOURCES-MIB.hrSystemProcesses"} ] uint32 NumberOfProcesses; Page 10

11 Namespaces A Namespace provides a context for grouping together the definitions of classes that describe the objects of interest in a managed environment. Managed System Na m espace Inheritance EnabledLogicalElement Association w Association with WEAK reference Aggregation w Aggregation with WEAK reference equivalent to : 0.. n System FileSystem OperatingSystem Key Fact: All CIM Operations are associated with a target namespace. Ok So Ialso need to know the Namespace that contains the definition of CI M_ OperatingSystem class. (See System Page (System) ComputerSystem (See System Page (System) InstalledOS See System Model page (File Systems)) BootOSFromFS 0..1 RunningOS w CreationClassName : string {key} Name : string {override, key} OSType : uint16 {enum} OtherTypeDescription : string Version : string LastBootUpTime : datetime LocalDateTime : datetime CurrentTimeZone : sint16 NumberOfLicensedUsers : uint32 NumberOfUsers : uint32 NumberOfProcesses : uint32 MaxNumberOfProcesses : uint32 TotalSwapSpaceSize : uint64 {units} TotalVirtualMemorySize : uint64 {units} FreeVirtualMemory : unit64 {units} FreePhysicalMemory : uint64 {units} TotalVisibleMemorySize : uint64 {units} SizeStoredInPagingFiles : uint64 {units} FreeSpaceInPagingFiles : uint64 {units} MaxProcessMemorySize : uint64 {units} Distributed : boolean MaxProcessesPerUser : uint32 Reboot() : uint32 Shutdown() : uint32 Page 11

12 Instance Names An <instancename> uniquely identifies a CIM Instance within a Namespace. It is comprised of a class name and the key properties defined for that class. [Propagated ("CIM_ComputerSystem.CreationClassName"), Key, MaxLen (256), Description ( "The scoping ComputerSystem's CreationClassName.") ] string CSCreationClassName; [Propagated ("CIM_ComputerSystem.Name"), Key, MaxLen (256), Description ("The scoping ComputerSystem's Name.") ] string CSName; The class name is easy.it's CI M_ OperatingSystem. But what do I use forthe key values? [Key, MaxLen (256), Description ( "CreationClassName indicates the name of the class or the " "subclass used in the creation of an instance. When used " "with the other key properties of this class, this property " "allows all instances of this class and its subclasses to " "be uniquely identified.") ] string CreationClassName; [Override ("Name"), Key, MaxLen (256), Description ( "The inherited Name serves as key of an OperatingSystem " "instance within a ComputerSystem."), MappingStrings {"MIF.DMTF Operating System 001.2"} ] string Name; Page 12

13 Parameters GetProperty <propertyvalue> GetProperty ( [IN] <instancename> InstanceName, [IN] <string> PropertyName ) An <instancename> uniquely identifies a CIM Instance within a Namespace.

21 Port Numbers 5988 (HTTP) 5989 (HTTPS) CIM Client CIM Server The DMTF recommends the use of the following well-known IP ports for use in compliant CIM Servers. This is a recommendation only and not a requirement for compliance with this specification. These port addresses have been acquired from IANA by the DMTF and are registered with IANA so are for the exclusive use for DMTF functions, in particular CIM Servers.

24 Architecture Components June San Jose, California A CIM Client issues CIM Operation requests and receives and processes CIM Operation responses. A CIM Server receives and processes CIM Operation requests and issues CIM Operation responses. A CIM Server consists of a CIM Object Manager and a variable set of additional components The CIM Object Manager (CIMOM) is the component of the CIM Server responsible for the implementation of the "protocol independent" semantics of CIM Operations. A CIM is responsible for the actual processing of CIM requests for one or more managed resources. It provides the mapping between the CIM interface and a resource-specific interface.

In addition, in some implementations, the CIM Repository may also contain instance data. However, as a general rule, management data (i.e., the information contained in CIM Instances) is owned and managed by the resource-specific management instrumentation. A CIM Server receives and processes CIM Operation requests and issues CIM Operation responses. A CIM Server consists of a CIMOM and a variable set of additional components The CIM Object Manager (CIMOM) is the component of the CIM Server responsible for the implementation of the "protocol independent" semantics of CIM Operations. The CIM Repository is a persistent store managed by the CIM Server. Page 29
