Data presentation and analysis

Edit online

The two major functions of IBM Z IntelliMagic Vision are performance monitoring and analysis, and tracking trends in workload and response time.

Performance monitoring and analysis

Run the IBM Z IntelliMagic Vision daily to ensure that outputs like health charts are accurate and precise.
Note: If you do not use trending reports regularly then you can run IBM Z IntelliMagic Vision only when necessary to investigate specific issues. Retain 7 days of information in the details table while using trending reports.

Tracking trends

The IBM Z IntelliMagic Vision trending function is used based on the assumption that IBM Z IntelliMagic Vision is run daily. These daily runs help ensure that the historical trend information can be loaded and maintained daily.

To enable the use of trending support, you must follow these steps:
  1. Create a project on the Welcome screen. This activates trending automatically.
  2. Go to Main window > Tools > Retention Settings. You can change the number of days to be kept per data level using Retention Settings.

    IBM Z IntelliMagic Vision automatically deletes data that is past the defined window.

  3. Define Shifts in the Reduce command file.
    Note:

    You can add, modify, or delete a Shift definition; however you must maintain reporting consistency. IBM Z IntelliMagic Vision uses the shift definitions as they exist at database load time and does not make retro-active changes.

    When you begin building trending databases, you can include the Shift definitions in the daily IBM Z IntelliMagic Vision cycle.

You can collect the data for historic trend analysis by calculating minimum, average, or maximum values per shift, per day. These daily roll-ups are called Yearly. They allow you to keep years of data available for historic trend analysis. The data is maintained as a sliding window.
