stats,streamstats command question

Path Finder

I'm going to check the permission and rejection of the scan attack per hour.
At this point, what I wrote...
Which is appropriate, Vlaues or the list?
Also, which one is suitable, stats or stream stats?


index="firewall" (action="allow" OR action="deny" ) AND ( attack="*scan")
| bin _time span=1d
| stats count by _time,src_ip,dest_ip,app
| stats values(dest_ip) AS dest_ip , values(count) AS count by _time,src_ip,app
| table _time, src_ip ,app, dest_ip , count

| stats count by _time,src_ip,dest_ip,app
| stats values(dest_ip) AS dest_ip , sum(count) AS count by _time,src_ip,app
| table _time, src_ip ,app, dest_ip , count

I have updated SPL, list() is an aggregation function it doesn't care of duplicates and by is clause for grouping.

@nnonm111  stats should work for your case changed span to 1h. 

index="firewall" (action="allow" OR action="deny" ) AND ( attack="*scan")
| bin _time span=1h
| stats count by _time,src_ip,dest_ip,app
| stats values(dest_ip) AS dest_ip , values(count) AS count by _time,src_ip,app
| table _time, src_ip ,app, dest_ip , count

instead of values(count) in second stats try sum(count)

thankyou 

I understand the difference between value and list is deduplication, which value will be removed?
Also, if you do list(app) and by app, the values are different.
What's the reason?

What's the difference if the app changes?
