Creating a time forecasting model

Use a time forecasting model to predict the future behavior of one or more performance metrics by observing their past behavior captured over time, by observing their time series.

This topic describes how to create a time forecasting model, which is part of Working-with-time-forecasting-models.

You can create other types of models using the same Wizard. Some of the steps may change depending on the model type, but the sequence remains the same.

The following video (2:27) illustrates the steps to create a time forecasting model to display resources that are likely to saturate in a given time.

To create a time forecasting model

1. In the Capacity Optimization console, click Workspace > All Domains> domainName  > Works folder.
2. In the working area at the right, at the top of the Works table, from the Add list, select Add model.
   
   In the TrueSight Capacity Optimization Wizard, follow the instructions on each page.
3. On the Model type page, select Forecast trends of system or business driver metrics (TIME FORECASTING MODEL) and click Next.
   

4. On the Scope page, specify the components you want to include in the model:

   1. Type: Select whether you want to include Systems or Business Drivers in the model
   2. Selection mode: To specify the entities to include in the model, select one of the following:

   • 
     
     • Entity Filter: If you select this option, from the Scope list, select a predefined entity filter for the model (see Filters).
     • Select list: If you select this option, for Systems or Business Drivers, select one or more systems or business drivers from Source and click  to add them under Selection. You can also drag and drop systems and business drivers from Source to Selection , or double-click them to move them from Source to Selection.
5. Click Next.
6. On the Template page, to specify a template to use for the model, select one of the following:
7. On the Template page, to specify a template to use for the model, select one of the following:

   • Predefined model template: If model templates exist for the selected entities for the model, select the Template group and the Template from the lists. The description of the selected template is displayed in the Template description box.

     Warning

     Note

     The Virtualization template group includes templates that are specific only to VMware virtualization. If your virtualization environment is VMware, you can select either the VMWare Virtualization or the Virtualization template group.

     If you select a model template, continue with Step 12.
     If no model templates are available for the current entities selection, the wizard informs you and the Custom model option is selected by default.

     Success

     Tip

     You can use a system template to simulate the commissioning or decommissioning of hosts and virtual machines. For more information about system templates, see Working-with-system-templates.

   • Custom model: Select this option if you do not want to use a template to create this time forecasting model.

8. On the Metrics page, select the metrics to include in the model and click Next.

   Warning

   Note

    If you selected a template for the model, the template defines the metrics, series, and thresholds, and this task is not relevant. Continue with Step 12.

9. On the Thresholds page, to specify which type of threshold to apply to the selected metrics, select one of the following:
   
   • No threshold: Thresholds are not applied.
   • Use Optimizer thresholds: The predefined Optimizer thresholds are applied.
   • Manual thresholds: Values are selected in the scenario.
   • Manual thresholds given by other metrics: For each resource included in the model, select the metric from which to copy the threshold.
     When you select this option, the Metrics list becomes available, select the metrics from this list from which to copy the threshold.
10. Click Next.
11. On the Name page, for Name and Description, type a name and description for the model.
    A default name based on the selected metrics, is displayed. You can change it as required. You can also click  to select the parameters you want to include in the model name.
12. Click Next.
13. On the Summary page, click Finish.
    The time forecasting model detail page is displayed, listing the systems to be consolidated and the available scenarios.
