Hyper-V Cluster Monitoring
Overview
A Failover Cluster is a group of independent computers that work together to increase the availability and scalability of Hyper-V Virtual Machines (VMs). Failover clusters also provide Cluster Shared Volume (CSV) functionality that provides a consistent, distributed storage that clustered roles can use to access shared storage from all nodes.
Applications Manager's Hyper-V Cluster Monitoring tool can discover your entire Hyper-V clusters and its underlying components through Hyper-V VMs. The Hyper-V Cluster group allows you to discover virtual resources and categorize them into Nodes, Storage, Network, Clustered VMs, etc.
Monitored Parameters
Hyper-V cluster groups will be listed among monitor groups and can be accessed from the 'Monitor Group' view under the Monitors tab. Within the Hyper-V cluster group,
- Summary tab provides an overall view of the components of the Hyper-V cluster and their health status. It shows you the cluster details along with the number of Nodes, Storage, Network, and Clustered VMs present in the Hyper-V cluster.
- Business View tab allows you to configure business views that help you visualize the inter dependencies between your Hyper-V clusters as well as view their health status.
- Dashboards tab lets you create your own custom pages by adding widgets into your dashboards. By using the Custom Dashboards feature, you can create dashboards of your choice - like Status View of all the Databases, Status view of all Web Applications deployed in the Tomcat Server, etc. If you create a dashboard as a template, the same dashboard can be reused across various Monitor Groups.
Below are the list of parameters that are monitored in the Summary tab:
Cluster Details
| Parameter | Description |
|---|
| Cluster Details |
| Number of Nodes | The total number of nodes in a cluster. |
| Max Nodes | The maximum number of nodes that can participate in a cluster. |
| Number of Networks | The number of networks used by the server cluster for communication. |
| Disks in Use | The number of disks currently in use in the cluster. |
| Quorum Owner Node | The node name, which currently owns the Quorum Resource. |
| Quorum Type | The current quorum type. The following are the possible values:- InputObject
- Cluster
- DiskOnly
- NodeAndDiskMajority
- NodeAndFileShareMajority
- NodeMajority
|
| Quorum Path | The path to the quorum files. |
Nodes
| Parameter | Description |
|---|
| Nodes |
| Node Name | Specifies the label by which the node is known. |
| CPU Utilization | The amount of CPU currently being used by the node (in percentage). |
| Memory Utilization | The amount of memory currently being used by the node (in percentage). |
Storage
| Parameter | Description |
|---|
| Storage |
| Disk Name | The name of the disk partition. |
| Volume Label | The volume label of the disk partition. |
| State | Current state of the disk partition. |
| Owner Node | The name of the node owning the disk partition. |
| Mount Points | The path of the disk partition. |
| Path | The absolute path (including the drive letter if present) of the disk partition. |
| Disk Space Details |
| Disk Name | Name of the disk space. |
| Disk Size (MB) | The total size of disk space (in MB). |
| Disk Used (MB) | The total used space in the disk (in MB). |
| Disk Free (MB) | The total free space available in the disk (in MB). |
| Disk Used Percentage (%) | The total percentage of used disk space in a cluster. |
| Disk Free Percentage (%) | The total percentage of free disk space in a cluster. |
Network
| Parameter | Description |
|---|
| Network |
| Network Name | Specifies the name of the network. |
| Address | Provides the IP address for the entire network or subnet. |
| Role | Provides access to the network's role property i.e, the role of the network in the cluster. The following are the possible values:- None - The network is not used by the cluster.
- Cluster - The network is used to carry internal cluster communication.
- Client - The network is used to connect client systems to the cluster.
- Both - The network is used to connect client systems and to carry internal cluster communication.
|
| Network State | Specifies the current state of the network. The following are the possible values:- Unknown - The operation was not successful.
- Unavailable - All of the network interfaces on the network are unavailable, which means the nodes that own the network interfaces are down.
- Down - The network is not operational; none of the nodes on the network can communicate.
- Partitioned - The network is operational, but two or more nodes on the network cannot communicate. Typically a path-specific problem has occurred.
- Up - The network is operational; all of the nodes in the cluster can communicate.
|
Clustered VMs
| Parameter | Description |
|---|
| Clustered VMs |
| Name | The name of the VM cluster. |
| Owner Node | The name of the node owning the VM cluster. |
| CPU Utilization | The amount of CPU currently being used by the VM cluster (in percentage). |
| Memory Utilization | The total amount of memory currently being used by the VM cluster (in MB). |
