correlation data from same index different soucetype

Symon
Explorer

I have the index=fortigate and there are two sourcetypes ("fgt_event" and "fgt_traffic").

index=fortigate sourcetype=fgt_event |stats count by user, assignip

userassignip
john192.168.1.1
paul192.168.1.2

 

index=fortigate soucetype=fgt_traffic | stats count by src srcport dest destport

srcsrcportdestdestport
192.168.1.1123410.0.0.122
192.168.1.2432110.0.0.222


I want to correlate the result like_

usersrc (or) assignipsrcportdestdestport
john192.168.1.1123410.0.0.122
paul192.168.1.2432110.0.0.222


I have learned SPL query like join,  mvappend, coalesce, subsearch ,etc. I tried a lot by combining the SPL functions to output. It doesn't still working. Please help me. Thanks.

Hi @Symon ,

don't use join because it's a very slow search, use stats in this way:

index=fortigate sourcetype IN (fgt_event, fgt_traffic )
| eval src=coalesce(src,assignip)
| stats 
   values(srcport) AS srcport 
   values(dest) AS dest
   values(destport) AS destport
   BY user src

If you want only the events present in both the sourcetypes, you have to add an additional condition:

index=fortigate sourcetype IN (fgt_event, fgt_traffic )
| eval src=coalesce(src,assignip)
| stats 
   values(srcport) AS srcport 
   values(dest) AS dest
   values(destport) AS destport
   dc(sourcetype) AS sourcetype_count
   BY user src
| where sourcetype_count=2
| fields - sourcetype_count

Ciao.

Giuseppe
