Understanding splunk configuration files | How to configure splunk?

Picture

Splunk configuration files are the main brains behind splunk working. Splunk configuration files contains Splunk configuration information. Splunk configuration  files controls behavior of splunk. These files are available on splunk server with extension .conf  and  easily readable and editable if you have appropriate access. Whatever changes we make through GUI seats in .conf files.Most of the time GUI does not offer full functionalities in that case we can achieve them through editing parameters in related .conf files.There can be multiple .conf files with same name.  Configuration files are stored in a number of directories, including $SPLUNK_HOME/etc/system/default (Do not touch them as they contain default configurations).Configuration files in $SPLUNK_HOME/etc/system/local, and $SPLUNK_HOME/etc/apps/ can be edited as per our need. we can create different folders in local folder as per apps or technologies.We must restart or debug refresh  splunk after editing .conf file to apply new changes to splunk.You don't need to remeber all of them but at least you should be  familiar about  which file conains what configuration settings.

Below is the list of all splunk configuration files and their short description.We will study frequently used configuration files  in detail in next chapters.
