Video 1-Creating VDI Groups and SLAs
To find the workload chart, select “workload” in the menu bar. panel depicts the current state of your environment and shows the current number of VMs. The right panel displays the expected improvements after executing the first set of actions. The workload chart is a 10x10 cell grid with the X and Y axis considering all metrics which encompass hosts and data center utilization respectively. Therefore, each cell represents risks to the infrastructure quality of service. Instead of trying to graph an individual point for each entity we summarized all infrastructure with one centered ring. The rings represent any virtual machines running within the cell’s range. The size of the ring correlates with the # of VMs for a given cell. Rings are distributed proportionately by utilization, and its colors range from blue, indicating underutilized VMs to red, indicating critically over-utilized VMs.
Let’s direct our attention to the expected improvements chart, and compare with our current state chart. We can see that there are fewer VMs running on over utilized data stores and hosts.
You can hover over any ring to see a detailed explanation about virtual utilization represented by that ring. Utilization of consumer VMs will be listed by descending levels of utilization, as well as the utilization range of host and data store provider.
To gain even more insight of a ring of interest, click on the ring, or multi-select rings by clicking and dragging. This will populate a window of the left displaying all the VMs within those rings, as well as any associated actions of those VMs as seen in another to-do lists, on the right. The VMs in the selected rings as displayed by their UI values in descending order. The VMs hosts and data store and their UI values are also displayed. The background color represents their risk to QoS. You can click on the entity to show its details; which helps analyze the UI value as well as any actions for that entity.
To modify the workload chart to enhance your analysis, you may choose a set of prefixed axis from the dropdown menu. Once selected the axis adjust to represent your environment based on those metrics. Alternatively, click the gear icon on the upper right corner to select each axis individually. The rings will adjust to correlate with your changed axis and will reflect the utilization of the chosen metrics.
Lastly, another way to modify the workload chart is to use the chart controls on the left side of the page. You can decide to hide certain rings, or change the axis values from the default percentages to the utilization index. You can still determine the percentages by counting cells in increments of 10%. The percentages help you understand UI values when you see then in other views.
