Foglight Capacity Manager 5.7.1 - User Guide

Calculating Slot Size Using Custom Size

To recalculate the slot size based on a custom size:
1
In the Overview pane, select Custom Size from the Slot Size drop-down list.
The Edit Slot Size button appears on the right side of the Slot Size drop-down list.
2
Click Edit Slot Size.
The Enter custom values dialog box appears.
3
Specify the values for CPU, Memory, Storage, and Throughput for the custom virtual machine.
4
Click Save.
The Enter custom values dialog box closes and the Clusters/Hosts pane is updated to reflect this change.

Clusters/Hosts pane

The Clusters/Hosts pane displays the details related to the selected virtual center or datacenter. This information is automatically updated when the Slot Size settings are modified. For more information, see Calculating Slot Size Based on VM. and Calculating Slot Size Using Custom Size .
The Clusters/Hosts pane includes the following capacity data:
•
Cluster Name (Clusters) or Name (Hosts): Name of the selected cluster or host
•
ESX Hosts (Clusters only): Number of ESX hosts in the selected cluster
•
Slot Size: CPU, Memory, Storage, and Throughput resources available on the virtual machine
•
VMs: Number of running virtual machines in the selected cluster or host
•
Slots Available: Number of available slots in the selected cluster or host
•
Constraint: Available constraint in the selected cluser or host
•
HA (Clusters only): If the HA policy is enabled for a cluster, Foglight Capacity Manager calculates the cluster resources and reserve the cluster resources that are required to satisfy the HA policy. A green check mark appears in the HA column when the HA policy is enabled.
 
 

Resource Utilization Tab

The Resource Utilization view displays information about the resource utilization of a selected virtual center or datacenter. It includes the following two panes:
•
Clusters/Hosts and Workload pane: Consists of the following two tabs:
•
Clusters: Provides detailed information about clusters that are available in the selected virtual center or datacenter.
•
Hosts and Workload: Provides detailed information about hosts that are available in the selected cluster.
To access the Resource Utilization view:
1
On the navigation panel, under Dashboards, click VMware > VMware Environment.
The VMware Environment dashboard opens.
2
Use the Group selector located at the top of the dashboard to select the virtual environment that you want to monitor.
3
On the Menu bar, click the Current Management tab, and click the Resource Utilization tab.
The Resource Utilization view appears at the bottom of the VMware Environment dashboard.
 
* 
NOTE: Enabling or disabling the HA policy, which is configured in vCenter®, is applicable for both the Clusters tab and the Hosts and Workload tab in the Resource Utilization view. If the HA policy is enabled for a cluster, Foglight Capacity Director calculates the cluster resources and reserve the cluster resources that are required to satisfy the HA policy. A green check mark appears in the HA column when the HA policy is enabled.

Clusters/Hosts and Workload pane

The Clusters tab and the Hosts and Workload tab display the details related to the selected virtual center or datacenter. This information is automatically updated after selecting a cluster.
The Clusters tab includes the following data:
•
Select a Cluster: Lists available clusters in the selected virtual center or datacenter
•
Resource Utilization
•
Current Capacity: Displays the current capacity of the selected cluster.
•
Peak CPU Performance: Displays the current CPU data of the selected cluster.
•
Recommendations: Displays recommendations on the resources to be added in the future to ensure that the resource utilization is balanced. Use the Settings dialog box to edit the Time Frame. For more information, see Analysis.
•
Resource utilization views: CPU Usage, Memory Usage, Storage Usage, and Storage IOPs Usage. The metric line in the white area is the history data, while the metric line in the gray area is the predicted data. For more information, see Resource Utilization view.
The Hosts and Workload tab includes the following data:
•
Select a Cluster: Lists available clusters in the selected virtual center or datacenter
•
Overview: Summarizes the host capacity of the selected cluster. Use the Settings dialog box to edit the Time Frame. For more information, see Analysis.
•
Host Requirement - Average Host Size view: Displays the number of Required Hosts and Available Hosts, if the existing server is used as the calculation benchmark.
•
Required Hosts: Indicate how many hosts to be required to support the usage of virtual machines. This number is populated based on the Average Host Size.
•
Available Hosts: Indicate the number of existing available hosts in the selected cluster
