You can set the time period and auto refresh rate of data with the following options:

View data

The View Data option enables you to view data on a target page based on a historical time period or in real time. This option is not available on all TimesTen target pages and only affects graphs. When a TimesTen target page has a View Data option it is located in the top right corner of the page with the following options:

  • Real Time

  • Last 2 Hours

  • Last 24 Hours

  • Last 7 Days

  • Last 31 Days

By default, every TimesTen target page uses a view data time period of Last 24 Hours. It is recommended to use the Real Time option of View Data when monitoring a TimesTen target.

Auto refresh

The Auto Refresh option enables you to control the auto refresh rate of a target page. This option is available on all TimesTen target pages and affects the whole target page. The Auto Refresh option is located in the top right corner of the target page and the options vary depending on the value of the View Data option.
