iCap modes

iCap can run in the following modes:

  • Observe
    Observe mode does not require policies. In this mode, iCap collects data, monitors MSU usage, and displays data in views. 

    Tip

    If you are new to creating policies, the information you collect in observe mode can help you to build a policy. 

    You can also test out a policy by running iCap in observe mode. Although iCap doesn't manage the LPARs, you can see some information about the LPARs on the POLOVER view.

  • Message
    Message mode is similar to observe mode but does require a policy. In this mode, iCap messages display the DC or GCL values that the product would set if it were running in manage mode. You can use message mode to preview the effects of a policy without actually changing anything. 

    Important

    In message mode, iCap considers only the current data for each interval when specifying DC and GCL values. That is, since iCap doesn't actually change DCs and GCLs, you might receive multiple messages stating duplicate information.

  • Manage
    In manage mode, iCap applies the selected policy. That is, the product actively manages DCs and GCLs for LPARs and capacity groups defined in the policy, and ensures that their sum does not exceed the MSU limit and CPCMSU limit.
