4 4 vfoglight Cartridge for Capacity Planning About vfoglight vfoglight helps IT organizations understand the virtual infrastructure by managing the relationships and interaction between all the components in the environment, including data centers, data stores, clusters, resource pools, hosts and virtual machines. With vfoglight Cartridge for Capacity Planning, administrators can quickly determine the root-cause of an incident or problem, track virtual machine (VM) movements and understand their impact, and identify contention for resources between virtual machines. About this Cartridge The vfoglight Cartridge for Capacity Planning provides projected consumption metrics of virtual and physical machines for CPU, network, memory, and storage requirements. Hosts can be selected and metrics can be compared. Charts are generated showing what happens when new physical or virtual machines are added to an ESX server.

13 1 Cartridge for Capacity Planning Views The vfoglight Cartridge for Capacity Planning ships with predefined views allowing you to forecast the projected capacities of Elastic Sky X (EXS) servers. This chapter contains the following sections: Why You Use the Cartridge for Capacity Planning...14 Accessing the Capacity Planning Dashboards...15 Using the Capacity Planner Dashboards...16 Capacity Planning Reports...23

14 14 vfoglight Cartridge for Capacity Planning Why You Use the Cartridge for Capacity Planning A host is a computer which can be a physical or virtual machine. Virtual machines (VMs) are quickly becoming the industry norm in IT infrastructures. Planning the addition of virtual machines to an Elastic Sky X (ESX) server can be a challenge for IT administrators. They lack the required metrics to properly forecast projected CPU, memory, network consumption, and storage requirements. Monitoring virtual machine environments with the vfoglight Cartridge for Capacity Planning simplifies the planning process and allows administrators to obtain projected, accurate metrics for virtual or physical machine capacity planning. Hosts can be selected and metrics can be compared. Charts are generated showing what happens when new physical or virtual machines are added to an ESX server. The Cartridge for Capacity Planning allows you select any number of VMs and predict their combined impact on the target ESX host s resources. You can also select an ESX host to see the resource impact caused by all of its resident VMs. One of the views excludes the disk consumption in situations where you want to focus on the ESX host itself and excludes the impact on external shared storage. The other view includes disk storage. The Cartridge for Capacity Planning thresholds are user configurable. You can change the hardware configuration of the physical ESX host (e.g., what if I had four more

15 Cartridge for Capacity Planning Views 15 Accessing the Capacity Planning Dashboards CPUs? What if I had 3.6 GHz CPUs? What if I had twice as much memory?, etc.). You can create and model what the VM loads look like on a hypothetical ESX server. Accessing the Capacity Planning Dashboards After installing the Cartridge for Capacity Planning, the VM Capacity Planning dashboard displays in the vfoglight Dashboards navigation panel. Note If the Capacity Planning dashboard is not present in the tree view of the navigation panel, see the vfoglight Administration and Configuration Guide or the vfoglight Installation and Setup Guide for installation procedures before continuing.

16 16 vfoglight Cartridge for Capacity Planning Using the Capacity Planner Dashboards The Cartridge for Capacity Planning provides the following dashboards: VM Capacity Planner Dashboard (See page 16.) VM Capacity Planner (No Storage) Dashboard (See page 22.) For detailed information about the workflow of Capacity Planning dashboards, see the vfoglight Cartridge for Capacity Planning User Guide. VM Capacity Planner Dashboard You use the VM Capacity Planner dashboard to build capacity planning usage scenarios and view graphs detailing consumption of projected: CPU capacity Memory capacity Network bandwidth Available storage

17 Cartridge for Capacity Planning Views 17 Using the Capacity Planner Dashboards From the VM Capacity Planner Dashboard you: Create Usage Scenarios you create capacity planning scenarios to project the CPU capacity, memory capacity, network bandwidth, and total available storage based on the actual system that will be used to host the virtual machines. Open Usage Scenarios after creating capacity planning usage scenarios, you may want to change the properties originally entered. Open Usage Scenarios allows you to open and reuse a host list for capacity analysis.

18 18 vfoglight Cartridge for Capacity Planning Edit Usage Scenario Properties after opening a usage scenario, you can make changes to tailor a scenario to meet your capacity planning needs, then save those changes. Select Hosts after creating the usage scenario, you assign and select the hosts you want to include.

19 Cartridge for Capacity Planning Views 19 Using the Capacity Planner Dashboards Select Target after selecting the hosts, you select the ESX server you want to use in the capacity planning analysis. Modifying Time Range Criteria prior to moving a VM to a new ESX host, it is recommended to look at a longer historical timeframe (e.g., Last Month, This Year, All Time) to a broader view of ESX host resource availability rather than using the default of the last four hours. If you end up with a large list of excluded

20 20 vfoglight Cartridge for Capacity Planning hosts, or VMs with insufficient data, you can experiment with shorter time intervals. After creating capacity planning usage scenarios, the following projected consumptions graphs and storage requirements are provided: Projected CPU Consumption (See page 20.) Projected Network Consumption (See page 21.) Projected Memory Consumption (See page 21.) Projected Storage Requirements (See page 21.) Projected CPU Consumption This view presents the total projected CPU consumption in gigahertz for the host(s) and time range selected. Hovering over an individual host displays a popup of CPU data for that host.

21 Cartridge for Capacity Planning Views 21 Using the Capacity Planner Dashboards Projected Network Consumption This view presents the total projected network consumption in megabytes per second for the host(s) and time range selected. Hovering over an individual host displays a popup of projected network consumption data for that host. Projected Memory Consumption This view presents the total projected memory consumption in gigabytes for the host(s) and time range selected. Projected Storage Requirements This view presents the total projected storage requirements in gigabytes for host(s) and the time range selected.

22 22 vfoglight Cartridge for Capacity Planning Viewing the Included and Excluded Hosts Pane The lower portion of the Capacity Planning dashboard provides a table view of projected consumption. It contains the following tabs: Included Hosts lists those hosts which had enough data to produce a projected consumption. Excluded Host - Insufficient Data lists those hosts which did not have enough data to project capacity planning data. You can do advanced searches from this view by clicking the Advanced button to search for an individual host. VM Capacity Planner (No Storage) Dashboard The VM Capacity Planner (No Storage) dashboard has the same views and functionality as the VM Capacity Planner dashboard. The only difference is that the Projected Storage Requirements view chart is not displayed. Virtual hard disk storage is usually separate from the ESX server. By not displaying the projected storage, a separate view of the projected metrics can be given, providing a clearer view of ESX server capacity.

23 Cartridge for Capacity Planning Views 23 Capacity Planning Reports Capacity Planning Reports The Cartridge for Capacity Planning provides the following report templates: ESX Host Capacity Trending this template is used to generate a report that shows projected CPU, memory and network usage values for the next 90 days for each ESX Host in the service. The projected values are calculated based on data observed for the past three months. Datastores Capacity Trending this template is used to generate a report that shows the capacity trending (used space, total space, growth rate per week, and time to full) for each datastore of each ESX host in the service. The projected values are calculated based on data observed for the past three months. For procedures on generating Capacity Planning reports, refer to the Managing Virtualized Environments User Guide.
