Generate a Capacity Forecast for an application by picking a workload mix and entering a growth plan. The forecast shows how the application’s capacity KPIs will trend at the projected volume.

Open the forecast generator

1. Open the Application Summary page. See Application Summary.

2. Click Generate Capacity Forecast in the Growth Plan-Based Forecast section.

What’s on the screen

1. Select Workload Mix. Two ways to build the mix:

• From a Week. Lists the top “taxing” transactions for the selected week.
• For a Capacity Metric. Lists the top transactions putting the most stress on the selected Capacity KPI.

2. Enter Growth Plan. Enter a growth plan for any listed transaction, or set an overall percentage increase for all transactions.

3. Transaction. The list updates based on the selected Workload Mix. If workload data is unavailable, you see the instances in the transactions instead.

4. Peak Throughput. The highest transaction volume in the analyzed period.

5. Analysed Growth Trend. A sparkline of the daily volume of each transaction for the selected week.

6. Growth Plan. A slider that goes up to 1000 percent.

7. Projected Peak Throughput. Calculated from the current volume and the projected percentage increase.

8. Generate Capacity Forecast. Click Generate Capacity Forecast for this Growth Plan to load the heat map.
