How to avoid comma separated delimiter being escaped by backslash in an event?

Hello Splunkers,

I have an event like this:

 

 

blocked,Adware,ABCD,test.exe,\\program_files\c\Drivers\,,,Generic PUA JB,,Endpoint Protection

 

 

I am extracting fields using comma separator delimiter, so my props.conf and transform.conf is:

 

 

transforms.conf

[cs_srctype]
CLEAN_KEYS = 0
DELIMS = ,
FIELDS = action,category,dest,file_name,file_path,severity,severity_id,signature,signature_id,vendor_product

props.conf 

[cs_srctype]
KV_MODE = none
REPORT-cs_srctype = cs_srctype

 

 

Now the output that I am getting is :

file_path = \\program_files\c\Drivers\,

severity=

severity_id= Generic PUA GB

signature=

signature_id= Endpoint Protection

vendor_product=

All the fields before file_path are getting extracted properly and after file_path are incorrect because it's adding comma and thus not separating properly. how do I ignore the \, and extract the fields properly.

Thank you in advance

Hi @mayurr98,

I tried out a new props that looks like it's getting the fields to ingest correctly - 

transforms.conf

[cs_srctype]
CLEAN_KEYS = 0
DELIMS = ,
FIELDS = action,category,dest,file_name,file_path,severity,severity_id,signature,signature_id,vendor_product

props.conf 

[cs_srctype]
KV_MODE = none
REPORT-cs_srctype = cs_srctype
SEDCMD=s/^((?:[^,]+,){4}[^,]+)(?<=\\),/\1\\,/


I've only added one additional line in the props - a sedcmd to add an escape to any trailing slash in the file_path segment.

With that config set up, the data is ingested with the correct vendor_product field:
