Splunk Search

Different element between two stats values() lists

rsaude
Path Finder
search made before ...| stats values(user) as AllUsers, values(usr_mod) as ModifiedUsers

And it returns two lists

Usr1            Usr4
Usr3            Usr2
Usr2            Usr1
Usr4            

My purpose is to get the users that weren't modified i.e:

 Usr3

Thanks in advanced,
Rsaude

@rsaude

OK, REGEX was wrong. I've fixed it.

Corrected Code

 | rex field=message "\[(?'usr'.*?)\].*\[(?'usr_mod'.*?)\]"

 | where eventcount=3 AND usr=usr_mod
 | stats values(user) as AllUsers, values(usr_mod) as ModifiedUsers | stats values(*) as * by AllUsers
  | eval check = if(match(ModifiedUsers,"^".AllUsers."$"),1,0)
  | stats values(eval(if(check=0,AllUsers,NULL))) as AllUsers

My bad, i got it to work with the full makeresult but i cant work it with my own, i'm gonna edit the original post and post the full query, there might be something wrong with the original query

i can't seem to change the question so i'll post it on the comments:

Here is the full query:
index=xxx (module=auth message="login") OR (module=user (message="modified*password" OR message="created user"))
| rex field=message "[(?'usr'.?)].[(?'usr_mod'.?)]"
| transaction startswith="created user" endswith="*modified*password
"
| where eventcount=3 AND usr=usr_mod
| stats values(user) as AllUsers, values(usr_mod) as ModifiedUsers

| where eventcount=3 AND usr=usr_mod

This query selects user and user_mod both have same value.
Hence, | stats values(user) as AllUsers, values(usr_mod) as ModifiedUsers result is same values.

there are 3 fields, user, usr and usr_mod, they do not have the same values

I see , sorry. I have a mistake.

| stats values(user) as AllUsers, values(usr_mod) as ModifiedUsers
what's this real results?

I thought they had the same value, but they seemed different.

@to4kawa you had it praticly right, with a few erros,

index=tenable (module=auth message="*login*") OR (module=user (message="*modified*password*" OR message="*created user*"))
| rex field=message "\[(?'usr'.*?)\].*\[(?'usr_mod'.*?)\]"
| transaction startswith="created user" endswith="*modified*password*"
| where eventcount=3 AND usr=usr_mod
| stats values(user) as AllUsers, values(usr_mod) as ModifiedUsers | stats values(*) as * by AllUsers
 | eval check = if(match(ModifiedUsers,"^".AllUsers."$"),1,0)
 | stats values(eval(if(check=0,AllUsers,NULL))) as AllUsers

You had
modefied and it was modified
missing " at the end of the first and second line
where is missing an AND between the conditions

my final purpose is to get the diference between all users that logged in and the users that changed their passwords on first login, just to check who didnt changed it on the first login.

index=xxx (module=auth message="login") OR (module=user (message="modified*password" OR message="created user"))

module: auth and module: user both have user field?

if the assumption is right, the query is simple.

index=xxx (module=auth message="login") OR (module=user (message="modified*password" OR message="created user"))
| stats dc(message) as flag by user
| where flag!=3

that can't be the case, because i need to have exactly 3 events in this order, one that is the creation of the account, other that is login and the last is the password reset. so i used transaction
