Foglight Capacity Manager 5.8 - User Guide

Projected Memory Usage view

This embedded view is part of the Resource Utilization > Clusters view. To display this view, click the Clusters tab in the Resource Utilization view, and select a cluster from the Cluster Name table.

Table 2. Projected Memory Usage view
Description

This view displays memory utilization metrics on the selected cluster.

NOTE: Unless otherwise indicated, the units of measurement for the following metrics are automatically converted for better plotting.
Data displayed
•
Utilization: This chart shows the actual memory usage.
•
Capacity: This chart shows the total memory capacity.
•
HA Capacity: If the HA policy is enabled on the selected cluster, this chart is plotted to show the actual memory usage.
•
Consume: Shows the current memory usage.
•
Growth Rate Per Week: Shows the growth rate of memory capacity per week.
•
R-squared: Indicates the accuracy of the forecasting data. This value is ranged from 0 to 1, and a higher value indicates that the forecasting data of utilization is more accurate.
•
Capacity: Shows the current memory capacity.
•
Time To Full:
HA enabled: Shows the period when the actual memory usage (the Utilization metric) exceeds the HA capacity metric. This metric is calculated based on the Growth Rate Per Week.
HA disabled: Shows the period when the actual memory usage (the Utilization metric) exceeds the total memory capacity (the Capacity metric). This metric is calculated based on the Growth Rate Per Week.
•
P-value: Indicates the dependency between the utilization and history time. This value is ranged from 0 to 1, and a lower value indicates that the utilization has a more significant dependency with the history time.

Projected Storage Usage view

This embedded view is part of the Resource Utilization > Clusters view. To display this view, click the Clusters tab in the Resource Utilization view, and select a cluster from the Cluster Name table.

Table 3. Projected Storage Usage view
Description

This view displays storage utilization metrics on the selected cluster.

NOTE: Unless otherwise indicated, the units of measurement for the following metrics are automatically converted for better plotting.
Data displayed
•
Utilization: This chart shows the actual storage usage.
•
Capacity: This chart shows the total storage capacity.
•
Consume: Shows the current Storage usage.
•
Growth Rate Per Week: Shows the growth rate of storage capacity per week.
•
R-squared: Indicates the accuracy of the forecasting data. This value is ranged from 0 to 1, and a higher value indicates that the forecasting data of utilization is more accurate.
•
Capacity: Shows the current Storage capacity.
•
Time To Full: Shows the period when the actual storage usage (the Utilization metric) exceeds the total storage capacity (the Capacity metric). This metric is calculated based on the Growth Rate Per Week.
•
P-value: Indicates the dependency between the utilization and history time. This value is ranged from 0 to 1, and a lower value indicates that the utilization has a more significant dependency with the history time.

Projected Storage IOPs Usage view

This embedded view is part of the Resource Utilization > Clusters view. To display this view, click the Clusters tab in the Resource Utilization view, and select a cluster from the Cluster Name table.

Table 4. Projected Storage IOPS Usage view
Description

This view displays storage IOPS) utilization metrics on the selected cluster.

Data displayed
•
iops: This chart shows the actual storage IOPs in the unit of connections per second (c/s).
•
Usage Changes: storage
•
Consumed: Shows the current storage IOPs (in c/s).
•
Growth Rate Per Week: Shows the growth rate of storage IOPs usage per week.
•
R-squared: Indicates the accuracy of the forecasting data. This value is ranged from 0 to 1, and a higher value indicates that the forecasting data of utilization is more accurate.
•
Capacity: This metric is not collected for the Projected Storage IOPs Usage view.
•
Time To Full: This metric is not collected for the Projected Storage IOPs Usage view.
•
P-value: Indicates the dependency between the utilization and history time. This value is ranged from 0 to 1, and a lower value indicates that the utilization has a more significant dependency with the history time.

 

 

Migration Modeler Tab

The Migration Modeler view uses historical data to simulate what would have happened if a specific Virtual Machine was running on a specific Host during that time period. This can be useful to predict what impact the virtual machine would have on the Host if it were moved to it. It includes the following elements:

•
VirtualCenter: Lists available VirtualCenters in the selected virtual center or datacenter.
•
Virtual Machine: Lists available virtual machines in the selected VirtualCenter.
•
Target Host: Lists available target hosts in the selected virtual center or datacenter.
•
Resource utilization related views: Projected CPU Consumption view, Projected Network Consumption view, Projected Memory Consumption view, and Projected Storage Consumption view. These views are automatically refreshed after selecting a VirtualCenter or a virtual machine.
To access the Migration Modeler view:
1
On the navigation panel, under Dashboards, click VMware > VMware Environment or Hyper-V > Hyper-V Environment.
The VMware Environment or Hyper-V 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
Click the Migration Modeler tab.
The Migration Modeler view appears at the bottom of the VMware Environment or the Hyper-V Environment dashboard.
