4.18.1 Range of listed JP1 events for a specified display period

The display period specification applies to JP1 events that have passed through an event acquisition filter, event receiver filter, severe events filter, or view filter.

To determine whether a specific JP1 event occurred during the specified display period, its arrival time at JP1/IM - Manager is compared with the current time of the JP1/IM - View host. Any discrepancy between the times of JP1/IM - Manager and JP1/IM - View could result in a JP1 event outside the specified display period being included in the listing. We recommend that you synchronize the time settings of JP1/IM - Manager and JP1/IM - View.

The following figures illustrate the range of JP1 events that are listed when you specify a display period.

Figure 4‒102: Range of listed events when the current time is 9:15 am on July 8

The numbers below correspond to the numbers in the figure.

  1. Range of listed JP1 events when the display period is one day and the base time is 9:00.

  2. Range of listed JP1 events when the display period is one day and the base time is 9:30.

  3. Range of listed JP1 events when the display period is two days and the base time is 9:00.

  4. Range of listed JP1 events when the display period is two days and the base time is 9:30.

When you use the integrated monitoring database, the listing specification applies to JP1 events saved in the database.

If you specify a start-time position for listing JP1 events with the integrated monitoring database, the range of JP1 events that are listed changes as follows:
