Hi,
It is fairly simple to setup a dashboard showing the counters of Incidents created and Closed on a daily basis.
But getting an average difference is harder, then you would probably need a ITSM Pro license and store the values as a KPI and do calculations on the store value.
To do the first part, navigate to Platform analytics > Dashboards
Create a new dashboard
Add a data visualisation
Use the single score setting (default)
Add a data source that filters incidents created on today.
Repeat the last three steps on the closed metric
