Use the Historical Summary workspace to begin troubleshooting problems that occurred in the recent past. For more information about the Historical Summary workspace, see Viewing the Historical Summary workspace.

About this task

The snapshot view can be either a summary, detail, or combined summary and detail panel.

Procedure

  1. Place your cursor before a specific Recording Time Interval in a historical summary workspace, type / and press Enter to view the Options Menu.
    The Options Menu is displayed.
    Tip: The options that are displayed usually mirror the options available from the equivalent real-time workspace.
  2. Choose an option from the Options Menu to open the associated Historical Snapshot workspace.
    For example, to open the CICS Region Overview (History) workspace that is shown in Figure 1,
    1. Place your cursor before a Recording Time Interval in the historical CICSplex Regions Summary workspace, Figure 2, type / and press Enter. The Options Menu is displayed.
    2. Type s and press Enter to choose the CICS Region Overview.

    A historical snapshot view of the CICS Region Overview workspace opens. A HISTORY indicator is highlighted in the header and footer area to clearly distinguish that the workspace contains historical rather than current data.

    The time of the current snapshot is highlighted in the footer area. Scrolling arrows are available either side of the current snapshot time. Use these arrows to scroll forwards or backwards to the next or previous snapshot. Alternatively you can enter the commands NEXT and PREVIOUS on the command line.

    Restriction: If the first subpanel in a workspace (generally the most important) is not eligible to show a historical snapshot, the equivalent real-time workspace opens. However, if the first subpanel is eligible to show a historical snapshot and another subpanel is not eligible, the following message is displayed for the ineligible subpanel.
    Message that is displayed when historical summary is not supported for a specific subpanel.
    Place your cursor over the message and press Enter to go to the general historical configuration workspace to show which attribute groups can be configured for near-term history data collection.
