Hello fellow Splunkers,
I am having this problem where i can not get rid of a field that shows up blank with no information in it. I have tried several ways to void out the blank space from the results table but have not had much luck. (I have tried saying that NOT (Account_Name="" OR User_Name="") along with other trys.)
Any help or sugestions would be greatly appreachiated.
index= "windows" source="wineventlog:security" NOT (Account_Name="NETWORK SERVICE" OR Account_Name="LOCAL SERVICE" OR Account_Name="*$" OR Account_Name="*lid*" OR User_Name="" OR Account_Name="" OR User_Name="lid*" OR User_Name="adm*" OR Account_Name="adm*") EventCode=529 OR EventCode=4625 | rex field=_raw "Account For Which Logon Failed:\W\s+\w+\W\S+\W\W+\S+\W\S+\W\s+\w+\W\w+:\W\W(?<cname>.+?)\W" |rex field=_raw "User Name:(?<cname>.+?)\W"| top limit=0 cname
The picture below will show that the fifth field has 45 hits, but no cname field. How do i void this/ get this out of my report?
(EDIT)
Below is the source event for the blank space that I am trying to void out of my report because it is generating to much data. I thank you so much for all the help you guys are willing to provide.
