Help with sql - monthly usage count

[amd]

Hello, I am new to sql and would like someone to help me. I am trying to create a script to manage usage\licenses

Below is a script I found but I would like to run\show by month ( last 3 months broken down by month )

script: select * From v$license;

result:
SESSIONS_MAX 0
SESSIONS_CURRENT 75
SESSIONS_HIGHWATER 96
USERS_MAX 0

Thanks!!

there is no history in this view.
if your license changes, you would need to take a snapshot of this view for the time periods you are interested in and then build the query around stored data.
