Microsoft Cluster Service metrics

The Microsoft Cluster Service (MSCS) metric groups are available for Windows Server 2000 and 2003. Even though the metric groups are labeled as Windows 2000, they are common across Windows Server 2012 R2 or later versions.

Windows MSCS Cluster Configuration

A cluster is a group of independent computer systems working as a unified computing resource. A cluster provides a single name for clients to use and a single administrative interface, and it guarantees that data is consistent across nodes.

The following table describes the Windows 2000 MSCS Cluster Configuration metric group.

Metric	Description
Cluster Name	The name of the cluster.
Major Version	Major version number of Microsoft Cluster Services software. Used to determine whether node can join cluster. A node can join a cluster only if one of the following is true: NodeHighestVersion=ClusterHighestVersion NodeLowestVersion=ClusterHighestVersion NodeHighestVersion=ClusterLowestVersion
Minor Version	Minor version number of Microsoft Cluster Services software. Used to determine whether node can join cluster. A node can join a cluster only if one of the following is true: NodeHighestVersion=ClusterHighestVersion NodeLowestVersion=ClusterHighestVersion NodeHighestVersion=ClusterLowestVersion
Build Number	Build number of Microsoft Cluster Services software. Used to determine whether node can join cluster.
Quorum Resource	Describes the resource selected to maintain cluster data.
Administrator Extensions	Provides the class identifiers (CLSIDs) for the Cluster Administrator extensions that are associated with the cluster. Their purpose is to extend the functionality of clustering administration by being able to support new types of cluster objects that are treated as resources.
Default Network Role	Specifies the Role (how the network will be used: client and/or private communication) that the cluster automatically assigns to any newly discovered or created network.
Description	Stores administrative comments about the cluster.
Security	Stores the security descriptor of a cluster. The security descriptor contains information related to a securable object.

Description	Provides comments about the network interface.

Windows MSCS Resource Configuration

A resource is a physical or logical entity (such as a disk or application) that is capable of being owned by a node, brought on and off line and managed by a cluster server object. It can be managed in a cluster. It can be hosted (owned) by only one node at a time. A resource is an instance of a resource type.

The following table describes the Windows 2000 MSCS Resource Configuration metric group.

Metric	Description
Resource Name	Name of resource (for example, disk or application).
Resource Type	Type of resource (see next section).
State	Indicates the state of the cluster resource. Possible values are: ClusterResourceStateUnknown ClusterResourceInherited ClusterResourceInitializing, ClusterResourceOnline ClusterResourceOffline ClusterResourceFailed ClusterResourcePending ClusterResourceOnlinePending ClusterResourceOfflinePending
Group	The cluster group contains resources related to cluster administration. Adding more resources to the group can hinder the ability to administer the cluster. Failure of any additional resources within the cluster group may trigger failover or inability to successfully administer the cluster. For best results and higher availability of the cluster, do not add resources to the cluster group. Instead, create groups for the additional resources, or place the resources in other groups within the cluster.
Owner Node	Node that currently owns the resource.
Characteristics	One of the following: CLUS_CHAR_UNKNOWN CLUS_CHAR_QUORUM CLUS_CHAR_DELETE_REQUIRES_ALL_NODES
Cryptographic Key Checkpoints	Defined for the resource. Related to security and registry information.
Registry Key Checkpoints	Defined for the resource. Related to security and registry information.
Dependencies	A dependent resource requires, or depends on, another resource to operate. For example, if a Generic Application resource requires access to shared physical storage, it would depend on a Physical Disk resource.
Dependents	Some resources have required dependents.
Flags	Flag Value indicating how to create the resource. Flag can be set to: CLUSTER_RESOURCE_SEPARATE_MONITOR. This value indicates that a separate Resource Monitor should be assigned to the newly created resource.
Network Name Dependency	The CLUSCTL_RESOURCE_GET_NETWORK_NAME control code retrieves the name private property of a dependent Network Name resource. This control code is unsupported by the other default resource types. Applications can use this control code as a Cluster Resource Control parameter.
Possible Owner Nodes	Possible owner nodes of resource.
Resource Class	Resource class is one of the following: CLUS_RESCLASS_UNKNOWN CLUS_RESCLASS_STORAGE CLUS_RESCLASS_USER
Administrator Extensions	Provides the class identifiers (CLSIDs) for the Cluster Administrator extensions that are associated with the resource.
Debug Prefix	Specifies the path to the debugger used to debug the resource.
Description	Provides comments about the resource.
Is Alive Poll Interval	Provides the recommended interval in milliseconds at which the Cluster service should poll the resource to determine if it is operational. The polling occurs when the Resource Monitor calls the resource DLL's IsAlive entry point function.
Looks Alive Poll Interval	Provides the recommended interval in milliseconds at which the Cluster service should poll the resource to determine if it appears operational. The polling occurs when the Resource Monitor calls the resource DLL's LooksAlive entry point function.
Pending Timeout	Sets the number of milliseconds that a Resource Monitor will wait for a resource DLL to update the status of a resource in an OnlinePending or OfflinePending state before terminating the resource.
Persistent State	Specifies whether the resource should be brought online or left offline when the Cluster service is started.
Restart Action	Describes the action to be taken by the Cluster service if the resource fails.
Restart Period	Defines an interval of time, in milliseconds, during which a specified number of restart attempts can be made on a nonresponsive resource.
Restart Threshold	Property specifies the allowable number of restart attempts that can occur within the interval defined by RestartPeriod before the Cluster service initiates the action specified by the RestartAction property.
Retry Period On Failure	Specifies the interval of time (in milliseconds) that a resource should remain in a failed state before the Cluster service attempts to restart it.
Separate Monitor	Indicates whether the resource requires its own Resource Monitor.

Windows MSCS Resource Type Configuration

A resource type is a server cluster object used to characterize and manage resources sharing similar characteristics. A resource type is implemented and manages all the resources of that type in the cluster. Types of resources include: DHCP Service, Distributed Transaction Coordinator, File Share, Generic Application, Generic Service, IP Address, Message Queuing, Network Name, Physical Disk, Print Spooler, and WINS Service.

Metric	Description
Resource Type Name	Name of resource type.
Characteristics	Characteristics of the resource type. This metric has one of the following values: CLUS_CHAR_UNKNOWN. These resources have no known characteristics. CLUS_CHAR_QUORUM. These resources can be the quorum resource type for a cluster. CLUS_CHAR_DELETE_REQUIRES_ALL_NODES. These resources cannot be deleted unless all nodes are active.
Possible Owner Nodes	List of possible owners of the resource.
Administrator Extensions	Provides the class identifiers (CLSIDs) for the Cluster Administrator extension DLLs that are associated with the resource type.
Description	Comments about the resource type.
Debug Control Functions	Indicates whether the Cluster service should create a separate Resource Monitor to use for debugging the control functions of a resource type.

Dll Name	The name of the dynamic-link library (DLL) for the resource type.
Is Alive Poll Interval	The recommended interval in milliseconds at which a Resource Monitor should poll resources of the particular resource type to determine if they are operational. The polling occurs when the Resource Monitor calls a resource DLL's IsAlive entry point function.
Looks Alive Poll Interval	The recommended interval in milliseconds at which the Cluster service should poll resources of the particular resource type to determine if they appear operational. The polling occurs when the Resource Monitor calls a resource DLL's LooksAlive entry point function.
