Correlating Data from 2 Indexes

[splunkcol]

I have 2 indexes, one called linux and another called firewall, how can I correlate both indexes to determine if the src field (of the linux index) is equal to the UserIP field (of the firewall index)

Hi @splunkcol,

let me understand: you have two indexes and you want to list all the IPs in both the archives indicanding if they are present in both or only in one, is it correct?

if this is your need, you could run something like this:

index=linux OR index=firewall
| eval ip=coalesce(src,UserIP)
| stats dc(index) AS dc_index values(index) AS index BY ip
| eval status=if(dc_index=2,"Both indexes",if(index="linux","Linux Index","Firewall Index"))
| sort ip
| table ip status

Ciao.
