How do I add or create license pools with a set of servers on a license master via CLI or by editing the server.conf file?

[Mayurmpatil]

I tried running this command, but no slave gets added in server.conf.

/opt/splunk/bin/splunk add licenser-pools pool_name -quota 10gb -slaves slave1,slave2 -stack_id enterprise

The below pool stanza gets added without slave servers:

[lmpool:pool_name]
quota = 10gb
stack_id = enterprise.

When I add the indexers in the pool from the console, I see something like this below:

[lmpool:test]
quota = 2147483648
slaves = C95CC0BB-CFEA-4D2A-A1A9-0FB12382FSCW,6386358F-1564-4F46-A961-35875BFB58F8
stack_id = enterprise

Also, how do I directly edit server.conf? How does this value generating exactly ? slaves = C95CC0BB-CFEA-4D2A-A1A9-0FB12382FSCW ---- this is server name , but not sure what it means to Splunk.

How do I get these added via CLI or updating server.conf ?

Hi @Mayurmpatil,

You need to provide Server (slave) GUID in below command, ref. doc https://docs.splunk.com/Documentation/Splunk/7.2.0/Admin/LicenserCLIcommands#Managing_license_pools

$SPLUNK_HOME/bin/splunk add licenser-pools pool01 -quota 10mb -slaves guid1,guid2 -stack_id enterprise

If you want to modify existing pool then you need to use below command

$SPLUNK_HOME/bin/splunk edit licenser-pools pool01 -description "Test" -quota 15mb -slaves guid3,guid4 -append_slaves true

Now the question is from where you will able to find GUID of each slave ? For this you need to check $SPLUNK_HOME/etc/instance.cfg file on each slave.

If you want to modify server.conf directly then you can do below configuration for every pool but when you modify server.conf directly you need to restart splunk on license master to take configuration into effect.

[lmpool:POOL_NAME]
description = ANY_DESCRIPTION
quota = POOL_SIZE_IN_MB
slaves = SLAVE_1_GUID, SLAVE_2_GUID, ..... , SLAVE_N_GUID
stack_id = enterprise

@harsmarvania57 : can I get the list of all the GUID on license master ( list of all the servers who are reporting to license master )

I dont want to login to each server are get their guid, as this is not possible to automate

[harsmarvania57]

You may try this REST API http://docs.splunk.com/Documentation/Splunk/7.2.0/RESTREF/RESTlicense#licenser.2Fslaves for automation but I am not 100% sure whether it will display all Slaves or only those are added into license pools.
