Is there a way to deduplicate event in summary index

Daniel_Pham

I created a report for finding list intersection of two set

A: inputlookup spam_ip (Indicator of compromise)

B: index=main (event log)

 

| inputlookup spam_ip | join srcip [ search index=main | rename ip  as srcip | fields srcip ] | summaryindex spool=t uselb=t addtime=t index="threat_summary" file="RMD55f183b338b214f84_487362985.stash_new" name="matches test" marker=""

 

and Time range : All day (because event in two sets grow daily,)

after the report  runs, it adds result into summary index. The problem is the result contains all event added before

Hi @Daniel_Pham 

why don't use a lookup command direclty?

I mean if you use static data from lookup on your search without a timestamp, is normal if you have duplicate.

Now I don't know your set of data, but try this search and let me know if works for you.

index=main | rename ip  as srcip | lookup spam_ip srcip

If this search works your schedule avoid to deduplicate the data

Regards

Alessandro

Your search works, but my expected results are events from lookup not main index

This is my lookup data

 

asn,classification,confidence,country,date_first,date_last,detail,id,itype,lat,lon,maltype,org,resource_uri,severity,source,actor,tipreport,type,srcip,domain,md5,email,url	

 

And all event data contains a ip field and not the same name. 

The schedule must be All day,  because any incoming event log from main index can be in lookup,  and vice versa
