source="testing.csv" host="so1" index="test_csv" sourcetype="test_csv"
| rex "(?<Test_ID>\d+),(?<name>.*)" max_match=0
| table Test_ID,name

 

1. source="testing.csv" host="so1" index="test_csv" sourcetype="test_csv" - This is just searching for a particular index, source, sourcetype.

2. | rex "(?<Test_ID>\d+),(?<name>.*)" max_match=0 - 

rex - It extracts fields inline from the events. The field extraction is not permanent. https://docs.splunk.com/Documentation/SplunkCloud/9.0.2305/SearchReference/Rex

"(?<Test_ID>\d+),(?<name>.*)" - It is regular expression as per my sample data. Try https://regex101.com/ for building the regex as per your data.

max_match=0 - It will allow rex command to match all matching field-values. Otherwise rex will only match the first occurrence.

Hi JGP,

You can create your own custom sourcetype to parse the events separately.
Let me give you an example : 
My Sample Data - 
Test ID,name
1,test1
2,test2
Test ID,name
3,test3
4,test4
Test ID,name
5,test5
6,test6

My Sourcetype configuration - 
[test_csv]
LINE_BREAKER=(\n+)Test
SHOULD_LINEMERGE=true

NOTE - You can define the other parameters as per your need.

This is how it parses the data :

If you want to extract fields, You can write your own REGEX to do it.
Here is how I did it using "REX" command. Just to showcase :

The query : 
source="testing.csv" host="so1" index="test_csv" sourcetype="test_csv"
| rex "(?<Test_ID>\d+),(?<name>.*)" max_match=0
| table Test_ID,name

Hope this helps.

Thanks.
