Measures reported by ScvmmHostGroupTest

A VMM host group is a logical entity that groups fabric resources together. You can group virtual machine hosts or clusters, or create nested host groups. After you have created host groups you assign and configure resources at the host group level. Those resources are then applied to all hosts and clusters in the group.

You can create host groups based upon different criteria. For example based on physical location, hardware capabilities, or specific workloads. You can assign permissions for host groups to the VMM admin, delegated administrators, and read-only admin user roles. Members of these user roles can view and manage the fabric resources that are assigned to them at the host group levels. When you create private clouds in VMM, you select which host groups will be included in the cloud, and then allocate resources in the host groups to the cloud.

At any given point in time, an administrator can use the ScvmmHostGroupTest test to know which are the groups that are managed by SCVMM, and how many services, clusters, hosts, and VMs are in each group. Detailed diagnostics also reveal which clusters, hosts, and VMs are in which group.

Outputs of the test: One set of the results for each group managed by SCVMM

Descriptor:Group

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Services Indicates the number of services in this group. Number

 

Clusters Indicates the number of clusters in this group. Number

The detailed diagnosis of this measure to know which clusters are part of this group.

Hosts Indicates the number of hosts in this group. Number

To know which hosts belong to the host group, use the detailed diagnosis of this measure.

Virtual_Machines Indicates the number of VMs in this group. Number

Using the detailed diagnosis of this measure, you can determine the hosts that are part of the group, and the count and state of VMs on each host.

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not DHCP guard is allowed for the port classification. In the graph of this measure however, the same is indicated using the numeric equivalents only.

enable_router_guard Indicates whether/not router guard is enabled for this port classification.  

This measure indicates whether router advertisement and redirection messages from authorized virtual machines pretending to be routers are dropped.

The values that this measure reports and their corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not router guard is allowed for the port classification. In the graph of this measure however, the same is indicated using the numeric equivalents only.

Enable_vmq Indicates whether/not virtual machine queue is enabled for this port classification.  

Virtual Machine Queue (VMQ) is a type of hardware packet filtering that delivers packet data from an outside virtual machine network directly to a virtualized host operating system.

The values that this measure reports and their corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not Virtual Machine Queue is enabled for the port classification. In the graph of this measure however, the same is indicated using the numeric equivalents only.

enable_IPsec_Off_load Indicates whether/not IPsec task offloading is enabled for this port classification.  

Another mechanism to offload network processing to hardware is IPsec task offloading. When large IPsec packets are used on the network, the IPsec task offloading feature can lower CPU utilizing on the Hyper-V host.

The values that this measure reports and their corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not IPSec task offloading is enabled for this port classification. In the graph of this measure however, the same is indicated using the numeric equivalents only.

Enable_iov Indicates whether/not single-root I/O virtualization enabled for this port classification.  

The single root I/O virtualization (SR-IOV) interface is an extension to the PCI Express (PCIe) specification. SR-IOV allows a device, such as a network adapter, to separate access to its resources among various PCIe hardware functions.

The values that this measure reports and their corresponding numeric values are listed in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not IPSec task single-root I/O virtualization is enabled for this port classification. In the graph of this measure however, the same is indicated using the numeric equivalents only.
