Summary

The Summary tab displays performance details for the selected capacity pool. Using the Summary tab, you can:

  • View the Usage, Efficiency and Risk indicators in bar charts.
    Each indicator bar chart shows the overall indicator value (Usage, Risk or Efficiency) of the capacity pool,  calculated by combining the different resources of that capacity pool.
    For example, the Usage indicator for a VMware system indicates the overall usage of the capacity pool, calculated by combining the usage of CPU, Memory, Storage resources of the capacity pool.
    The bar chart for this indicator includes the following metrics:
    • CPU: CPU usage of the element, aggregated from the underlying VMware hosts.
    • Memory: Memory usage of the element, aggregated from the underlying VMware hosts.
    • Disk: Disk/storage usage of the element, aggregated from the underlying VMware hosts.

    Note

    The resources per indicator are based on the platform that is selected.

  • View utilization charts for essential metrics such as CPU, memory, total storage and total file size on an hourly and daily basis.

For more information on how to use the Usage, Risk and Efficiency indicators to gauge the health of you capacity pool, see  Using Usage, Risk,and Efficiency indicators.

  • View tooltips for each indicator, that is for Usage, Risk and Efficiency. When you hover over each individual resource bar (CPU, Memory, or Storage), a tooltip displays the score of the underlying element, in percentage, with a brief reasoning of the score. This information can help you quickly identify any problem area and determine any remedial action that may be required. For information on how these scores are calculated, see the Capacity Pool Indicator Computation PDF.
    For more information about how to use indicators, see Using Usage, Risk and Efficiency indicators.

Viewing virtualization details in the Capacity Optimization console

You can directly navigate from a capacity pool view in TrueSight Presentation Server to TrueSight Capacity Optimization, and further explore that capacity pool view's corresponding virtualization view, in the Capacity Optimization console.

Click  Launch in infrastructure-specific view in the contained element row for which you want to view the virtualization details in the Capacity Optimization console.

Tip

The  action menu is located to the left of the Name column.

The corresponding virtualization view opens in the Capacity Optimization console in a new tab of the browser.

If you click  Launch in infrastructure-specific view in another element row, the same browser tab that launched the Capacity Optimization console earlier, refreshes with the new content.

Note

Viewing a specific view page in TrueSight console depends on the access role privileges and permissions of the user that is logged into TrueSight Presentation Server. For example, if you are logged in with a capacity planner role in TrueSight Presentation Server, you will see only those details in the virtualization view in that your role has access rights to. For more information on access rights, see Adding and managing roles and Configuring user authentication.

Sorting and filtering columns

You can sort and filter the systems you want to display in the Contained Elements table.

  1. To sort systems, hover your cursor at the end of the Name column.
    A dropdown icon is displayed.
  2. Click to display the available options.
  3. Sort the container pool names alphabetically, or use the available filters to display the required container pools.

Similarly, you can sort each indicator column.
