Using drill downs is a convenient way to investigate a given problem in more details. You can either drilldown to a viewlet’s details within the Console panel, which is the default method, or to a target dashboard (including the current dashboard) that utilizes variables. The variable filter from the data selected in the originating viewlet is passed to the specified dashboard and updates that dashboard’s viewlets using the variable.
The following is an example scenario of drilling down to a target dashboard:
- Dashboard #1: Contains a viewlet with data for average temperature by state. You have configured this viewlet to drilldown to Dashboard #2 using its state variable.
- Dashboard #2: Contains the following three viewlets which have a filter defined for state:
- Temperature by city
- Humidity by city
- Rainfall by city
When you select a specific state within the viewlet located in Dashboard #1, you will be brought to Dashboard #2. All three viewlets in Dashboard #2 will reflect data for the state selected from Dashboard #1’s viewlet.
The following video covers the basics of drill downs in both setting up the dashboard to drill into and the one from which the drill down is being done. This also covers self drill down which was added in version 1.2.
