Configure data collection on forwarders with inputs.conf

You can configure data inputs on a forwarder by editing the inputs.conf configuration file.

In nearly all cases, edit inputs.conf in the $SPLUNK_HOME/etc/system/local directory. If you have an app installed and want to make changes to its input configuration, edit $SPLUNK_HOME/etc/apps/<appname>/local/inputs.conf. For example, if you have the Splunk Add-on for Unix and Linux installed, you would make edits in $SPLUNK_HOME/etc/apps/Splunk_TA_nix/local/inputs.conf.

Do not make changes to the inputs.conf in $SPLUNK_HOME/etc/system/default. When you upgrade, the installation overwrites that file, which removes any changes you made.

Whenever you make a change to a configuration file, you must restart the forwarder for the change to take effect.

Edit inputs.conf

1. Using your operating system file management tools or a shell or command prompt, navigate to $SPLUNK_HOME/etc/system/local.
2. Open inputs.conf for editing. You might need to create this file if it does not exist.
3. Add your data inputs.
4. Once you have added your inputs, save the file and close it.
5. Restart the forwarder.
6. On the receiving indexer, log in and load the Search and Reporting app.
7. Run a search and confirm that you see results from the forwarder that you set up the data inputs on:

host=<forwarder host name or ip address> source=<data source> earliest=1h
