+### Widget Static Link
+On the right top of every widget on the dashboard, there is a `Generate Link` option, which could generate a static 
+link to represent this widget.
+By using this link, users could share this widget, or integrate it into any 3rd party iFrame to build a 
+network operations center(NOC) dashboard on the wall easily.
+About this link, there are several customizable options

+2. `Auto Fresh` option is ON with 6s query period and last 30 mins time range. Query period and range are customizable.
