remove specific folder from input

[Nawab]

I have configured syslog-ng to listen on multiple ports, save them in a folder with IP name and hf to send logs to indexers, 

In one case i have 127.0.0.1 sending as loopback to syslog-ng server, now i want to remove this IP from my input configs.

let suppose I have below folder

/opt/syslog/Fortigate

under fortigate I have mutiple fortigates sending logs and i dont know in future we can add a new fortigate here 1 hot is 127.0.0.1, i want to remove this from my inputs, what should I do.

I just pasted blacklist 127.0.0.1, and when I ran list monitor all 127.0.0.1 is remove, is it correct or should i used your method

Hi @Nawab 

That should work too, its using a regex to match so 127.0.0.1 I guess will also match 🙂

Hi @Nawab 

Modify the inputs.conf file on your Splunk forwarder to add a blacklist entry for the specific directory you want to exclude.

Locate the stanza for your directory input, e.g. [monitor:///opt/syslog/Fortigate], and add the blacklist line.

[monitor:///opt/syslog/Fortigate]
disabled = false
# ... other settings like index, sourcetype ...
blacklist = /opt/syslog/Fortigate/127\.0\.0\.1/.*

This configuration tells Splunk to monitor the /opt/syslog/Fortigate directory but ignore any files or subdirectories within the /opt/syslog/Fortigate/127.0.0.1 path. The \. escapes the dots in the IP address, and /.* ensures that everything within that specific directory is excluded.

After saving the changes to inputs.conf, you must restart the Splunk forwarder for the changes to take effect.

Check out the following inputs.conf docs on blacklist of files: https://docs.splunk.com/Documentation/Splunk/latest/Admin/Inputsconf#:~:text=way.%0A*%20No%20default...
