Data exceptions in the Virtual Planner

If the page displays less data than expected after Selecting-data-for-a-virtualization-study, follow the steps given below before beginning a Creating-a-new-virtualization-study:

• Verify that the following data request parameters are correct:
  • Domain
  • Entity filter
  • Time range: Ensure that the time range defaults to last 30 days. If required, update the range using the calendar icon.
• Verify data exists for the systems in the domain/entity filter during the Time Period displayed at the top of the New Study page.
  • View systems and metrics in Workspace to ensure that data exists for the systems.

Viewing data exceptions on the first screen of a study

If data is not displayed after verifying the above details, and No computers available is displayed, click on Consolidate to Virtual or any other study to view the Exceptions section in the first screen.

The Exceptions table shows computers, grouped by platform and exception category, with issues that prevent them from being included in the study. A brief description of the issue is included in the table. Use the platform list to view exceptions for each platform. The most common reason that a computer appears in this table is that there is no collected data for the specified time period.

To view a detailed list of the computers not available for the study, click the magnifying glass icon in the upper right corner. The Computer Exceptions page provides a more detailed list of the requested computers with exceptions.

Some of the common exceptions are listed below:

• No CPU utilization information present for computer(s) within the time period requested: Use the Workspace to find a time range for the system where the metric CPU_UTILMHZ has valid values. Use the calendar icon on the New Study screen to select the new time range
• Benchmark capacity cannot be retrieved: Indicates that Performance Rating Basis specified in Virtual-Planner-Settings is not available for the system. Use the Workspace to view the Reference Benchmark section of the Summary information for the system to identify which benchmark values are defined for the system. If alternate benchmark values are available for the system and are valid for your study, use Settings to change the Performance Rating Basis to the defined benchmark
• No performance rating used information available: Indicates that the absolute amount of CPU used by the guest or partition, expressed in the Performance rating basis specified in Settings, could not be determined. This can be due to the inability to link a guest or partition to a valid virtual host or a host with a Reference Benchmark value matching the Performance Ratings Basis. The latter may be addressed as described under “Benchmark capacity cannot be retrieved”
• No memory configured information available: Indicates the value for the TOTAL_REAL_MEMORY metric is not valid. A valid value must be supplied for this metric. This needs to be done manually, through the Workspace, or by correcting the data population process.
