SCVMM Host Groups Test

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 SCVMM Host Groups 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.

Target of the test : SCVMM

Agent deploying the test : An internal agent

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

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the SCVMM server being monitored

Port

The port at which SCVMM listens. The default is 'null'.

Domain, Username, Password, and Confirm Password

The eG agent runs PowerShell scripts on SCVMM to pull metrics. To run these scripts, the eG agent requires the permission of an SCVMM administrator with 'read-only' privileges. In order to grant this permission to the eG agent, configure the Username and Password parameters of this test with the credentials of an SCVMM administrator with 'read-only' privileges. Confirm the password by retyping it in the Confirm Password text box. Then, specify the domain to which this user belongs against the Domain text box.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
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.

The detailed diagnosis of the Clusters measure lists the clusters that are part of a host group.

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

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