What is Auto-Refresh

At runtime, when the Dashboard loads in the browser, data is fetched from the data sources and Widgets are drawn.
After this, if the user doesn’t interact with the Dashboard, no new data is fetched and the data displayed can become outdated.

Instead, when Auto-refresh is configured, new data is fetched at regular intervals without needing user intervention.

Auto-refresh ? Buffer refresh ?

Auto-refresh will perform the same action on data as a manual refresh of the web page.
This may be insufficient to get new data if your Connections are bufferized.
For more information on the Buffer and how to refresh it, see the relevant Chapter in the Connecting to Data chapter.

Important note on Performance

The minimum allowed Time Interval is 30s.
This is for performance reasons on the web server as well as the data server when many users will leave open an auto-refreshed dashboard.

Use this setting sensibly, considering the number of queries that can result from many users leaving the dashboard open on different computers.
