Add an indexer to a license pool

This topic discusses adding indexers to existing license pools. Before you proceed, you may want to review these topics:

• Read "Groups, stacks, pools, and other terminology" in this manual for more information about Splunk license terms.

How indexers access license pools

Access to a license pool's stack is controlled by that pool's license master. A pool can be configured to allow access only to specific indexers, or to all indexers who connect to it by specifying the URI and management port of the license master.

Add a specific indexer

Follow these two basic steps to give a specific indexer access to a given license pool's stack:

1. Configure the indexer to be a license slave and give it the license master's URI and management port. To do this, follow the instructions in "Configure a license slave" in this manual.

2. Configure the pool on the license manager to accept access from that indexer. To do this, follow the instructions in "Create or edit a license pool" to edit a license pool, choose the radio button option to only allow access to Specific indexers and then click the plus sign next to the names of the indexer in the list of Available indexers to move them into the list of Associated indexers.

Add any indexer that connects

Follow these steps to give all indexers who connect to this license master access to a given license pool's stack:

1. Configure the indexer to be a license slave and give it the license master's URI and management port. To do this, follow the instructions in "Configure a license slave" in this manual.

2. Configure the pool on the license master to accept access from any indexer. To do this, follow the instructions in "Create or edit a license pool" to edit a license pool, and choose the radio button option to allow access from Any indexer that connects.
