Manage licenses from the CLI
This topic describes how to use Splunk CLI commands to monitor and manage your licenses. It covers some of the main uses and options of the CLI licensing commands. The definitive reference to any CLI command is the command's online help.
For general information on the Splunk CLI, see "About the CLI".
For information on managing licenses through Splunk's REST API, refer to "Licenses" in the REST API Reference Manual.
CLI license commands and objects
You can use the CLI to add, edit, list, and remove licenses and license-related objects. The available commands are:
|add||licenses, licenser-pools||Add a license or a pool of licenses to a license stack. This command is only available if you have an Enterprise license.|
|edit||licenser-localslave, licenser-pools||Edit the attributes of a license slave or a pool of licenses. This command is only available if you have an Enterprise license.|
|list||licenser-groups, licenser-localslave, licenser-messages, licenser-pools, licenser-slaves, licenser-stacks, licenses||Depending on the object specified, lists either the attributes of that object or members of that object.|
|remove||licenser-pools, licenses||Remove licenses or license pools from a license stack.|
License-related objects are:
|licenser-groups||the different license groups you can switch to.|
|licenser-localslave||a local indexer's configuration.|
|licenser-messages||the alerts or warnings about the state of your licenses.|
|licenser-pools||a pool, or virtual license. A stack can be divided into various pools, with multiple slaves sharing the quota of each pool.|
|licenser-slaves||all the slaves that have contacted the master.|
|licenser-stacks||this object represents a stack of licenses. A stack contains licenses of the same type and are cumulative.|
|licenses||all licenses for this Splunk instance.|
The following are examples of common licenser-related tasks.
To add a new license to the license stack, specify the path to the license file:
./splunk add licenses /opt/splunk/etc/licenses/enterprise/enterprise.lic
To list all the licenses in a license stack:
./splunk list licenses
List also displays the properties of each license, including the features it enables (features), the license group and stack it belongs to (group_id, stack_id), the indexing quote it allows (quota), and the license key that is unique for each license (license_hash).
If a license expires, you can remove it from the license stack. To remove a license from the license stack, specify the license's hash:
./splunk remove licenses BM+S8VetLnQEb1F+5Gwx9rR4M4Y91AkIE=781882C56833F36D
Managing license pools
You can create a license pool from one or more licenses in a license stack (if you have an Enterprise license). Basically, a license stack can be carved up into multiple licenser pools. Each pool can have more than one license slave sharing the quota of the pool.
To see all the license pools in all the license stacks:
./splunk list licenser-pools
To add a license pool to the stack, you need to: name the pool, specify the stack that you want to add it to, and specify the indexing volume allocated to that pool:
./splunk add licenser-pools pool01 -quota 10mb -slaves guid1,guid2 -stack_id enterprise
You can also specify a description for the pool and the slaves that are members of the pool (these are optional).
You can edit the license pool's description, indexing quota, and slaves:
./splunk edit licenser-pools pool01 -description "Test" -quota 15mb -slaves guid3,guid4 -append_slaves true
This basically adds a description for the pool, "Test", changes the quota from 10mb to 15mb, adds slaves guid3 and guid4 to the pool (instead of overwriting or replace guid1 and guid2).
To remove a license pool from a stack, specify the name:
./splunk remove licenser-pools pool01
Managing license slaves
A license slave is a member of one or more license pools. The license slaves access to license volume is controlled by its license master.
To list all the license slaves that have contacted the license master:
./splunk list licenser-slaves
To list all the properties of the local license slave:
./splunk list licenser-localslave
To add a license slave, edit the attributes of that local license slave node (specify the uri of the splunkd license master instance or 'self'):
./splunk edit licenser-localslave -master_uri 'https://master:port'
Monitoring license status
You can use the list command to view messages (alerts or warnings) about the state of your licenses.
./splunk list licenser-messages
Swap the license master
