Dashboard playback
You can use dashboard control buttons (Pause, Rewind, and Forward) to view the available data of
the dashboard and widgets in playback mode. Auto-refresh of data will not occur in playback mode.
•
Pause button — Use the Pause button to pause function in playback mode.
•
Rewind or Forward button — Use the Rewind or Forward button in playback mode to show the
data automatically for every 20 seconds based on the selected time scope.
If you click the Rewind or Forward button for the first time, data refresh will be in 1x speed with
5 minutes or 30 minutes granularity based on the time scope.
For example, consider the current time as September 9, 2013, 7:00 AM. In the Scope list, if
you set the duration as 30 minutes and the time scope as September 9, 2013, 6:15 AM, data
will be displayed for all the applicable widgets based on the given time range (September 9,
2013, 5:45 AM to September 9, 2013, 6:15 AM).
In this example, September 9, 2013, 5:45 AM will be the start time and the selected
September 9, 2013, 6:15 AM will be the end time.
If you click the Forward button, all the applicable widgets in the dashboard will show the data
with the granularity of 5 minutes as follows:
•
First refresh will display data from September 9, 2013, 5:50 AM to September 9, 2013,
6:20 AM.
•
Second refresh will display data from September 9, 2013, 5:55 AM to September 9, 2013,
6:25 AM.
•
Third refresh will display data from September 9, 2013,6:00 AM to September 9, 2013,
6:30 AM.
If the start date is within 8 days from the current date, then the granularity will be 5 minutes. If
the start date is beyond 8 days (8 to 30 days) then the granularity will be 30 minutes.
For example, consider the current time as September 9, 2013, 6:00 AM and the selected time
is August 25, 2013, 6:00 AM.
If you click the Forward button, all the applicable widgets in the dashboard will show the data
with the granularity as of 30 minutes as follows:
•
First refresh will display data from August 25, 2013, 6:00 AM to August 25, 2013, 6:30
AM.
•
Second refresh will display data from August 25, 2013, 6:30 AM to August 25, 2013, 7:00
AM.
•
Third refresh will display data from August 25, 2013, 7:00 AM to August 25, 2013, 7:30
AM.
If you click the Rewind or Forward button successively for second, third, and fourth time, the
data refresh will change to 2x, 3x, and 4x speed respectively. On the fifth click, the data refresh
resumes to 1x speed. A label indicate the playback speed. A tooltip for the label will display the
duration of the data refresh, based on granularity.
For example, if you select the start time within 8 days and set 3x speed, the tooltip will show
Speed (3x):15 minutes.
If you select the start time beyond 8 days and set 3x speed, the tool tip will show Speed (3x):90
minutes. Once the playback reaches the current time, it will change to the Stay current option
and the widgets will start refreshing in regular intervals.
