Splunk licensing question

OldManEd — Sat, 06 Jun 2020 14:53:22 GMT

Is there any way I can create a stand-alone Splunk instance using another instance’s license?

I would like to create a full featured, stand-alone Splunk development system consisting of one search head and one indexer. I’m not concerned about the forwarder. I could use the Splunk ~free~ license, but I would really like this development environment to have all the features of the existing ones, (i.e., Alarming).

Paying for more licenses is not in the books. We do have 2 existing Splunk instances here with extra capacity. What I would like to do is use the extra capacity from one of those for my development instance. Is this possible?

Sure. Set up the new instance as a license slave connected to the instance having your current license. They exchange spent volume regularly, just make sure the slave gets a connection at least once per 24 hours.

One question, do I set up the search head as a slave also?

Typically every non-forwarder instance will be license slave to the license master.

If the search head doesn't have access to a Splunk Enterprise license, there won't be any alerting or user authentication running on the search head.

OK, great. And thanks again.

Martin,

OK, problem here with this configuration. When I logged in to the server acting as the license manager this morning, there were warning messages telling me that “Daily indexing volume exceeded for 2 slaves.” I found out that I needed to create a “pool” and place my test environment servers in the pool. So I did that.

Then I restarted the master license server Splunk instance and the messages disappeared. But as soon as I started the Splunk test environment Splunk instance, the messages came back. Is this ~normal~ operation for Splunk?

If you have more pools than just the autogenerated one then yeah, you need to configure your indexers into pools... without a pool they don't have assigned license volume.

Not quite sure about the warning, check if that disappears by tomorrow as license-related warnings (pool warning in this case) are on a per-day basis.

I realise this question is quite old, but for those viewing this answer today I would recommend getting a developer license:
