Resource Planning

CPU, memory and disk resources are allocated according to the Resource Plan within the configuration.

Resource Planning nodes are top-level Application Groups or User Groups that define how the overall system resources are allocated. Each Resource Planning node contains one or more sub-nodes to match specific Application Groups or User Groups. Each sub-node then contains one or more rules match application attributes.

In this section:

Evaluation Order

Performance Manager evaluates items in the following order to apply the Resource Plan:

  1. Resource Planning nodes in descending order.
  2. Resource Planning sub-nodes in descending order.
  3. Resource Planning sub-node rules in descending order.

The arrows in the navigation pane and work area show the order of precedence.

In the above example, the Development node is evaluated first. If the user matches the User Group, then the sub-nodes under Development are evaluated.

Resource Planning Nodes

Resource Planning nodes are top-level User Groups or Application Groups. Resources are first allocated to the Resource Planning nodes. Finer control can be applied by adding sub-nodes for specific Application Groups or User Groups.

Add Resource Planning Nodes Based on User Groups

  1. Select the Resource Configuration navigation button.
  2. Select Resource Planning from the navigation tree.

  3. On the Resources Setup ribbon, click Add Users/Groups and select Select User/Group.

    The Select User/Group dialog displays.

  4. Choose a user or group using one of the following methods:

    • Enter the name of a user or group in the Name field.
    • Click the percent sign (%) and add an environment variable.
    • Click the ellipses (...) and browse to the user or group.

The User Group is added as a Resource Planning node to enable its resources to be managed.

  1. Select a Resource Planning node from the navigation tree.
  2. Select either Move Up or Move Down from the Resources Setup ribbon.

The Resource Planning node is moved up or down in the list.

CPU Share Factor

CPU Share Factor allows the CPU resource to be split between Resource Planning nodes.

It allocates User Groups or Application Groups a greater or lesser proportion of CPU time.

The pie chart in the work area provides a visual representation of the CPU allocation between the nodes. In the above example, the pie chart represents the relative CPU share between the Resource Planning nodes entitled Development, HR, Sales and <Other Users>.

To set CPU Share Factor:

  1. Select a Resource Planning node in the navigation tree.
  2. In the work area, select the CPU tab.

  3. In the CPU Share Factor section, adjust the share factor by either using the slider or entering a value into the box.

    As the CPU Share Factor is adjusted, the pie chart updates to provide a visual representation of the resource allocation between the Resource Planning nodes.

The CPU Share Factor of the Resource Planning node, relative to the other Resource Planning nodes, is set and the processor time is split accordingly on endpoints.

Resource Planning Sub-nodes

Sub-nodes allow a finer level of control to be applied for specific Application Groups or User Groups. Rules within a Resource Planning sub-node allow resources to be allocated based upon attributes of the application window, such as whether it is maximized or minimized.

Add Resource Planning Sub-nodes Based on Application Groups

  1. Select a Resource Planning node from the navigation tree.
  2. On the Resources Setup ribbon, click Add Applications and select an Application Group for which to create a Resource Plan.
