6-11 Viewing Recent-Past Data
You can switch the display between incoming real-time data and replaying saved data for recent activity.
For replay, you can view only data included in the active data collection cycle (for example, within the last day).
The amount of active data retained in the OVNPM database at any site is determined at installation. Check with
your OVNPM administrator to determine the active data collection period at your site. There are two methods to
display recent-past data:
Method Description
Scroll View snapshots of recent-past data across a period of time
Animate View the animated replay of recent-past data
To switch to recent-past data from real-time monitoring, choose the Previous Period option from the Options
menu. As a result, the display freezes on the previous period.
To access recent-past data for a specific time period, you must first specify an exact time reference.
6-11-1 Specifying Exact Time Reference for Recent-Past Data
Time references affect the information displayed by providing the following:
• Date and time of the data to be displayed
• Collection time interval, which determines the degree of granularity of the data.
To specify a time reference, select the Time Reference option from the Options menu. This opens the Time
Reference Selection dialog box, which lists the previous 20-time references, used.

If the time reference you need appears on the list, select it and then click on the OK button. The view changes to
display data for the selected time period. If the time reference and interval you need are not included in the list,
then you can add a new reference.
