38. Reports » Devices » Filters

Clicking on a Filter anywhere in the Console opens a tab with specific data. The tab has sub-tabs at the bottom. Each sub-tab shares these common toolbar fields:

Filters – Select the Filter of interest, or All. Administrators can limit which Filters guests can access
Time Range – Select a predefined range, or Custom… for a specific time interval

38.1. Filter Dashboard

This sub-tab displays widgets using data collected by Filters. Its configuration is global (not specific to just one Filter), so any changes here are also visible in other Filter Dashboards. The Reports » Dashboards chapter describes general dashboard operations.

Filter widget configuration is explained in the following paragraphs.
