About this task

Define two points in time for Service Mapping to perform comparison. For example, if you know that the business service functioned well up until a certain time and after that it experienced problems, you can compare this business service before the problem started and after to see the summary of changes that possibly led to the event.

  2. Click View Map next to the required business service.
  3. Navigate to the history view you need by setting the time interval in the history area:
    1. Set the time range of the history slider by clicking the hour, day, week, or month icons.

      Click the hour, day, week, or month icons to set the time range of the history slider.
