How to edit a configuration file

Before you edit a configuration file, make sure you are familiar with the following:

Customize a configuration file

To customize an attribute in a configuration file, create a new file with the same name in a local or app directory. You will then add the specific attributes that you want to customize to the local configuration file.

  1. Determine whether the configuration file already exists in your preferred directory, for example $SPLUNK_HOME/etc/system/local. See Configuration file precedence in this manual.
  2. If the file already exists in your preferred directory, edit the existing file. Otherwise, create the file in your preferred directory. Do not copy the contents of the default configuration file into the file in your preferred directory. This is to ensure that any Splunk software upgrades properly update the default values.
  3. Add only the stanzas and attributes that you want to customize to the local file.

Clear an attribute

You can clear any attribute by setting it to null. For example:

forwardedindex.0.whitelist = 

This overrides any previous value that the attribute held, including any value set in its default file, causing the system to consider the value entirely unset.

Insert a comment

You can insert comments in configuration files. To do so, use the # sign:

# This stanza forwards some log files.

Important: Start the comment at the left margin. Do not put the comment on the same line as the stanza or attribute:

[monitor:///var/log]    # This is a really bad place to put your comment.

For an attribute, such as

a_setting = 5  #5 is the best number

This sets the a_setting attribute to the value "5 #5 is the best number", which may cause unexpected results.

Creating and editing configuration files on Windows and other non-UTF-8 operating systems

The Splunk platform works with configuration files with ASCII/UTF-8 encoding. On operating systems where UTF-8 is not the default character set, for example Windows, configure your text editor to write files in that format.
