Producing Graphs and Reports

HP Capacity Advisor can generate both graphical and tabular data for presentation.

The Profile Viewer presents data for one entity at a time within a browser-based application that allows you to manipulate the data view, including panning through graphical presentations, changing utilization limit values, and instantly collecting more data or selecting a different period of data to view.

Utilization reports are produced as HTML pages that can be viewed immediately or downloaded in a compressed file for viewing offline in a web browser. Full reports can be obtained for all utilization resource types (CPU, memory, network I/O, disk I/O, and power usage) for one scenario at a time or for one or more systems or complexes and their associated workloads.

A scenario comparison report helps you to compare key values for 2–4 scenarios at a time in a format that makes it easier to look across the scenarios at one time. Comparison reports are also produced in HTML format and are available in a downloadable compressed file for later viewing in a web browser.




	NOTE: When measuring CPU utilization of virtual machines, it is possible for the reported utilization to be greater than the number of virtual CPU cores (vCPU cores) associated with the virtual machine. While the number of virtual machine host threads allocated to the process for the virtual machine is restricted to the number of virtual CPU cores, the virtual machine host threads used to implement virtual hardware, such as I/O cards, are not restricted. Under certain load conditions, this can result in CPU utilization of more than 100% being reported for a virtual machine. (For information on how utilization is calculated for each resource, see Appendix B .)

Utilization Reports Overview

Capacity Advisor Utilization Reports provide valuable summaries and details of resource usage for CPU, memory, network and disk I/O bandwidth, and power consumption and costs. These reports are useful for understanding current resource utilization or planning for future requirements. Reports can present resource utilization for a scenario, or for one or more complexes, systems, or workloads.

A fundamental difference exists between reports based on scenarios and those generated by directly specifying systems, complexes, and workloads. All metrics reported in scenario-based reports rely on summing the workload data to create a simulated perspective. When generated based on direct specification of systems, complexes, and workloads, reports rely on collected data from real systems for each resource type, which may differ from the sum of the workloads used in simulations.

Reports based on scenarios provide the easiest way to simulate a combination of systems and workloads. Complexes cannot be specified as components in a scenario, so reports on complexes must be generated by direct selection of the complex option.

Prerequisites

To generate a report:

You must be logged in to HP Systems Insight Manager. (See “Accessing Capacity Advisor”.)
You must have already collected data on the systems of interest (see “Gathering Data for Capacity Advisor”).
You must be authorized and licensed on all systems you wish to include in the report (see VSE Management Software Version 4.0 Getting Started Guide ).

Note the available date range of all collected data, which appears above the date range selector, and the default date range (30 days prior to the current day).
If the default date range is acceptable, click Next.
If a different data set is desired, change the date and time, then click Next.
The Select Details screen opens.

Procedure 5-20 Select Details Specific to Report Type

Select one or more types of resources for which you want to see data from among CPU, memory, network I/O, disk I/O, and power by clicking the appropriate check boxes.
Select the type of scale for data presentation: percentage of allocated resource, absolute numbers, or both by clicking the appropriate radio button.
Check the default graph size. The default size fits just within a letter-size page for printing.
If you prefer dimensions smaller or larger, use the drop-down to change width (in pixels).
If you prefer a different width-to-height proportion, use the Aspect Ratio drop down.
If you chose trend report details,
1. Select the Business Interval (default: 1 week).
  Requiring higher percentages of valid points can make the business intervals analyzed more meaningful, but can also reduce the number of business intervals available for the analysis, making the overall analysis less useful.
2. Select the minimum percentage of valid data points that must be present within the period (default: 95%), called the Valid Threshold.
3. Choose the data aggregation type (default: average), called Compute Trending of.
If you chose power report details,
1. Designate the currency label to use in power report tables.
2. Designate a typical cost for power per kilowatt-hour.
3. Optionally, designate a cooling cost multiplier.
  See “Scaling Multipliers”.
4. Designate a time interval for display of results (default: by day).
Click Finish.
The Report Created screen opens.
Click the appropriate link to browse the report in a web browser or to save the report to the location that you designate.
