License Management

Note: Splunk 3.0 has a new license format. Your Splunk 2.x license will not work with Splunk 3.0. Contact splunk support for a new license.

All Splunk Servers have a license in the subdirectory $SPLUNK_HOME/etc/splunk.license. There are two types of license; the Splunk Free license and the Splunk Enterprise license. Enterprise enables higher volume indexing and additional features. You must purchase a separate license for every instance of Enterprise Splunk that you deploy.

When you first install Splunk, you are allowed to run unlicensed for 30 days. After that you are asked to obtain a Free or Enterprise license. The free license simply requires you to register with Splunk. You are prompted to register when you first install and when you run Splunk unlicensed.

Example of a Splunk license:

Installing or updating a license

If you are performing a new installation of Splunk or switching from one license type to another (for example from Free to Enterprise), you must update your license. You can update your license from the CLI or SplunkWeb interface.

  • If you are installing a new Splunk enterprise license for the first time, you will need to log in with the default administrator account: username "admin" and password "changeme".
  • You must obtain your license from the email that you received from splunk.com after you signed up for a free trial or purchased Enterprise Splunk.

Installing or updating a license using SplunkWeb (using a web browser)

  1. Start Splunkweb from inside a web browser.
  2. Go to the Admin -> License & Usage -> Change license interface tab. Paste your new license into the text box.
  3. Go to the Admin -> Server -> Control tab. Restart the Splunk Server.

From the command line

  1. Navigate to the splunk.license file, located in the ./etc/ directory of the Splunk home directory.
  2. Copy your new or previous license key file into ./etc/splunk.license beneath your Splunk home directory.
cp -p splunk.license /opt/splunk/etc/
  1. When the correct license is in place, start or restart the Splunk Server.
/opt/splunk/bin/splunk restart
