The Capacity Planning Summary card gives you a quick visual indication of usage and estimates when a meter, representing physical equipment or resources, will run out of capacity. This helps ensure that you have enough to run your workloads, and alerts you to take action when needed, to prevent a shortage from becoming an outage.
You can display the full Capacity Planning page in your HPE GreenLake Central dashboard. You can filter by the account displayed (if you have access to more than one), and by service. You can also group by available options by service, and change the past and future date ranges for forecasting.
Please note the following with respect to the Capacity Planning summary card:
- Capacity planning only applies to HPE services, not to public cloud services.
- The actual usage in the capacity planning chart is based on the billed usage, not the actual physical resource usage. Actual usage may exceed the installed capacity if the physical hardware resource consumption is less than the allocation, due to hypervisor and storage optimization technologies.
- Enhancements to the data presentation for aaS capacity planning are in process. Meantime you can enter a value in Installed Capacity for VMaaS and other standard services in the Manage Rates page, for the purpose of showing capacity planning for these services.
- Azure Stack Services are consumption-based, not allocation-based. Capacity planning is not applicable to this service.
Azure Stack Compute is similar to other HPE GreenLake core services; HPE Consumption Analytics gets both Installed Capacity and Actual Usage, and supports capacity planning against this hardware.
Understanding the summary chart
Meter capacity is calculated based on actual usage against installed capacity (typically requested capacity plus a buffer of 10%). Installed capacity can vary on a day-to-day basis, as hardware is brought in and out of service for maintenance purposes.
The card chart display varies depending on whether the selected tenant has one account with meters that support capacity planning, or more than one account with meters that support capacity planning.
For tenants that have only one account with meters that support capacity planning, the card shows the meters in a stacked bar chart, in descending order by percentage of installed capacity used:
For tenants that have more than one account with meters that support capacity planning, the chart shows a table:
The table has a row for each billing account, and a column for each status. The numbers in a row indicate the number of services in each status:
- Critical means available meter capacity is running out (based on actual usage between requested and installed, not by percentage of installed capacity used)
- Low means meter usage is below its committed capacity
- Forgotten means usage is a very low percentage of installed capacity
- Optimal means the meter is using the installed capacity at an optimal rate.
Meters for which usage is decreasing are hidden.
You can navigate to the full report in your dashboard by clicking the Details link in the bottom right hand corner of the card, or by clicking any row.
Viewing the Capacity Planning report
The full page view shows more detail, on a per meter basis, for the selected account. Next to each meter name, the percentage of installed capacity used is displayed. The detail for the first meter in the list is expanded by default. You can expand or collapse the detail for any meter, to view the actual usage and anticipated charges for the meter, and compare those to the corresponding requested, installed, and committed capacities.
Understanding the Capacity Planning chart
The charts shown for capacity planning show consumption trends for actual usage and forecast data over a period of time based on the forecast filters. The charts will show installed capacity and actual/forecast usage over a period of time, and colored bands may be shown based on contractual values (requested capacity and committed capacity).
Depending on the Group by selection, the charts may show colored bands to indicate where the actual usage falls with regard to the contractual values Requested Capacity and Committed Capacity.
- Critical – Range between Requested Capacity and Installed Capacity
- Optimal – Range between Committed Capacity and Requested Capacity
- Low – Range from 10% of Committed Capacity to Committed Capacity
- Forgotten – Range from zero to 10% of Committed Capacity
The units on the y axis of the charts are based on the configuration in the billing account. The height of the bands is also determined by configuration, since the committed and requested capacities are input values, and the installed capacity is calculated based on the requested capacity..
In the charts, actual usage is shown as a solid line. When you hover the mouse pointer over a past date, a tooltip shows you installed capacity, actual usage, requested capacity, and committed capacity for that date:
In the chart, forecast usage is shown as a dotted line. When you hover the mouse pointer over a future date, a tooltip shows you the installed capacity, forecasted usage, requested capacity, and committed capacity for that date:
Understanding the Capacity Planning table
The report also shows the values for the selected meter in a table; while the chart shows values by day, the table shows values by month.
This accounts for small variations in usage values between the tooltip and table, as in the examples shown above.
For the selected meter, the table shows rows for usage, installed capacity, requested capacity, and committed capacity, and columns for each month (future months' usage values are forecast, as shown in the column headings). Increases or decreases in installed capacity and actual usage from the previous month are shown to the left of the actual values (in green and red, respectively).
You can scroll to view all months, or resize the columns in the table.
Filtering, grouping, and setting forecast date ranges
You can filter by the account displayed (if you have access to more than one), and by service. You can also group by available options by service, and change the past and future date ranges for forecasting:
This example shows the grouping options for the VM service:
If you group by a level for which Requested Capacity and Committed Capacity values don't apply, you'll see the following warning:
If you see this warning, select a different option from the Group by pulldown list.
