About Splunk Light licensing

Splunk Light licenses control the indexing volume and feature set of the Splunk Light product. Users can increase the indexing volume capacity on a per-GB basis.

Splunk Light license types

Splunk Light ships with a free license and offers paid license options that you can buy.

License Type Description
Splunk Light Free Included with the Splunk Light download package. This license offers up to 500MB daily indexing volume and a single administrator account.
Splunk Light Perpetual Offers a daily indexing volume capacity up to 20 GB and up to 5 administrator or user accounts.
Splunk Light Term Offers a daily indexing volume capacity up to 20 GB and up to 5 administrator or user accounts. You can renew this license at the end of its subscription term.

Exceeding your license

Warnings and violations occur when you exceed the maximum daily indexing volume allowed for your license.

Warnings

If you exceed your daily indexing volume on any calendar day, you get a warning. The message persists for fourteen days. You have until midnight to resolve it before it counts against the total number of warnings within the rolling 30-day period.

Violations

If you have five or more warnings in a rolling 30-day period, you are in violation of your license. During a license violation period:

  • Splunk Light continues to index your data.
  • Search is disabled, except for searches to the _internal index.

Although you cannot search existing or incoming data inputs, you can still use search to troubleshoot the licensing issue.

Search capabilities return when you have fewer than five warnings in the previous 30 days or when you apply a reset license.

License expiration

When your Splunk Light Term license expires, you can do one of two actions: Update your license or Revert to the Splunk Light Free License.

You cannot convert the instance to a Splunk Forwarder or switch between license groups.

Update your license

Update your license to install a new Splunk Light license or install a Splunk Enterprise license to upgrade to Splunk Enterprise.

When your Splunk Light license expires and you upgrade to Splunk Enterprise, your data, searches, alerts, knowledge objects, and settings should migrate seamlessly. If you have add-ons enabled, they remain active and appear in the Apps browser view of Splunk Enterprise.

See "About migrating Splunk Light" and "Update your Splunk Light license".

Revert to the Splunk Light Free license

When your Splunk Light license expires and you revert your instance to Splunk Light Free, your instance limits to a single account with administrator privileges. Previous settings such as accounts, passwords, and configurations persist, though you cannot modify them in Splunk Light Free. If you upgrade this instance back to Splunk Light (or upgrade to Splunk Enterprise), your previous configurations restore.

To log in after you revert to Splunk Light Free

If you have more than one admin account configured on the Splunk Light instance, after you revert to Splunk Light Free, the login account becomes the admin account that is first in alphabetical order.

To change this, do the following:

1. Stop Splunk Light Free.

2. Back up the original <SPLUNK_HOME>/etc/passwd file.

3. Edit <SPLUNK_HOME>/etc/passwd file to remove all entries except one Admin user.

4. Start Splunk Light Free.

5. Log in using the Admin account you saved.

When you upgrade back to Splunk Light or Splunk Enterprise, remember to restore the passwd file from the original backup.

Comments

Uspinar, your Splunk Light Trial license should automatically revert to a one-year Splunk Light Free license at the end of the 30-day trial period.
