I am running a ingestion and records comes every 15 min
one of the field is integer #user
value might be 1, 2,3 or what ever.
what I am trying to do is average of sum ( users) per hour
for example
rec1 - 10:00am { user: 1}
rec2 - 10:15am { user: 5 }
rec3 - 10:30am { user: 5}
rec 4 - 10:45am { user: 1}
now average (sum (user)) should be = (1+5+5+1 / 4) = 3
how do I get that in kibana?
