Hi @bapun18,
you can find all the information you need in the License Usage Report [Settings -- License -- License Usage -- by inddex or host or ...]
or using the Monitoring Console [settings -- Monitoring Console].
If you'r still not satisfield you can use the following App https://splunkbase.splunk.com/app/3178/
I usually use the Monitoring Console for my analysis.
Ciao and Happy Easter.
Giuseppe
