Using the Database Replay Slider Control

The Slider Control allows you to position your Database Replay at a specific date and time by dragging the 'thumb track' backwards or forwards to the desired position. The buttons at either end of the Slider will show the start and stop dates of the Database Collection and can be clicked to open a date selection box.

Simply drag the slider to the required location and then release it. The Display windows will only be updated once the slider has been released.

Web Application

In the Web Application, the slider control is shown as the icon at the top of the database Control Bar. It can be dragged from one side of the Display to the other to show data by the collection intervals.

Windows Client

Keyboard Support

While the Slider has focus, you can make use of keyboard actions to control its functions:

Left Arrow or Up Arrow

Move one interval backward in time

Right Arrow or Down Arrow

Move one interval forward in time


Move to the beginning of the replay.


Move to the end of the replay.

Page Up

Move one "page*" backwards in time.

Page Down

Move one "page*" forward in time.

* Page - A "page" is usually the number of intervals displayed by the largest chart in the current Display.

Current Position

If you hover your mouse over the slider, a 'tool tip' will show the current position of the replay. The current position is the time of the data that is currently being shown and on graphical charts this is also indicated by a vertical line through the graph.

Due to the limited resolution of the slider (maximum of approximately 25 steps), when you have a large database, moving the slider minimally could result in a large interval jump.

Time Mode

The time mode of the slider can be set independently of the corresponding data window. This is done by using the context menu, which is opened by right-clicking over the Slider. The options available include:

Data - timestamps are shown in the time zone where the data was collected.

Local - timestamps are shown in the time zone where the Windows Client is running.

Server - timestamps are shown in the time zone of the server that the Windows Client is connected to.

UTC - timestamps are shown in Co-ordinated Universal Time

However, this setting is not permanent and will reset if the Database Replay is restarted.

Picking the time mode

Since time modes are associated with windows and you can have multiple windows per Display and multiple Displays can participate in a replay session, the time mode of the slider is determined by:

  • The Display that started the replay. If you drill-down from this Display to other Displays, the time mode of the slider is not changed.

  • The most popular time mode in the Display that started the replay. This excludes windows that do not display any data, e.g. title windows and link windows.

Data time

When the data time zone is not consistent across all the windows and Displays in the replay session, the slider will go into 'multizone' mode, in which case the data time zone is ignored and the local Windows Client time zone is used.


  • After the replay is started, changing the time mode of individual windows will not affect the time mode of the slider.
