Indicator sources are based on a facts table (for example, Incident [incident]) and the
conditions to gather data for indicators. One indicator source can be shared by multiple
indicators (1:n relationship).
If you want to use the indicator source to create a snapshot of the situation on a certain
date, the conditions should include a date related filter, so you can schedule a historic data
collection for it. Choose your indicator sources carefully. Since an indicator is linked to an
indicator source, it is not easy to change the indicator source after you created it.
Note: Indicator sources must be created before an indicator can be
created. Also, in the indicator definition an aggregation needs to be applied (count, sum,
average, max, min) to the record set of the indicator source and, if needed, additional
Create indicator source by incident state
To create indicators based on the states of
incidents, use the following indicator sources: Incidents.New, Incidents.Open, and
Incidents.Resolved. You can also define an incident dashboard with tabs grouping the incidents
by state, and adding the appropriate indicators to this dashboard.
