About Upload File

Hi guys,

I am new here and I want to explore some things in splunk. I have a txt file, I uploaded it and I want to get the logs in this file by combining them according to a certain format. For example, a log that starts with line D and ends with line F. I created a .conf file for this and restarted splunk, but does it also affect the existing logs, do I need to throw these logs again, so how can I delete the existing one and throw it again. What is your view of the whole event?

Hi @tanjiro_rengo ,

are you inputting using manual guided Data Input or an input in conf file?

is you can use manual Data Input you can do this withou any issue.

If you need to use inputs.conf, you must remember to rename the file and use crcSalt=<SOURCE> in inputs.conf otherwise Splunk doesn't read twice a file.

About deleting, you can use the delete command in the search dashboard, but you must before assign to your user the "can_delete" role otherwise, also an admin, cannot delete any log; remember at the end of this action to remove this role for your user (it's safer!).

Obviously, this is a logical deletion, not a physical deletion, for the physical deletion you can only use the splunk clena eventdata -index <your_index> command by CLI, but in this way, you delete all the data in an index. not only the last file.

Ciao.

Giuseppe

hi @gcusello

First of all, thank you for your reply. There's something here I'm curious about. If the .conf file I have added contains the correct content, if I want to upload the same file with a different name, is the result in the review section correct or should I see the search section?

Hi @tanjiro_rengo ,

as I said, it depends on how you upload the file: is you use the manual Data Input by web GUI, you can upload the file many times without ani issue.

If instead you are using a conf input, Splunk doesn't index twice a log, so you sould rename it and use the option crcSal=<SOURCE>.

Ciao.

Hi @tanjiro_rengo

It ultimately depends on what configuration file changes you have applied to determine if this is a search-time or index-time change. Index-time changes will not apply retrospectively to existing indexed data.

Please could you share you configuration changes and let us know how you are sending this file to Splunk?
