Hi Splunkers

I need to extract this log below each SMB Path to make a count:

LOG Example:

Here are the SMB shares available on the remote host when logged in as "user account"

  • ADMIN$
  • IPC$
  • Teste
  • Users

I need results came with below :

Action = Here are the SMB shares available on the remote host when logged in a
User = "user account"
Path = ADMIN$
Path = IPC$

Path = Teste
Path = Users

I tried using regex but I can only bring all path together.

Thanks for Help

try this rex:
It might need some sort of modification...but at least it will give you idea...

...|rex  field=_raw "(?s).*\"\s+(?<Action>.*)as\s*(?<User>[^:]+)"|rex max_match=0 field=raw "\s*(?<Path>\w+)\$*[\r\n]\s+"

Can you include the raw event in your question? If the above represents the raw event, please use the code button (101010) to format it to make it more easy to work with.
