How many master Splunk instances can one Enterprise license be installed on?

Can one enterprise license can be installed on only one master Splunk instance? Or more?

Yes, you have the ability to designate one splunk host as a license master and make other splunk hosts license slaves. The other alternative is to install the license on each host which can be a bit much in a larger deployment. See: http://docs.splunk.com/Documentation/Splunk/6.4.1/Admin/Configurealicensemaster

In theory, since you can install the same license on multiple machines, you could have multiple license masters but a license slave can only be the slave of one license master.

I'm pretty sure you're break all kind of legal thingys by doing this In theory, since you can install the same license on multiple machines ....

[splunk_force_as]

A central license master isn't required. So you could install the same enterprise license on multiple machines. Unless that has changed? @MuS Each host would still be fall under that same license.

Also, it depends on the use-case and the deployment.

I will get someone from Splunk legal department to answer this question .... pls hold the line ...

I'ed be curious to know how this works as well, I don't see any clear answers on using the same license on potentially different environments that require segregation for security requirements for example.

Thanks MuS

You could also try to put a load balancer in front of a "cluster" of license masters as well. It depends on your use case.

According your description "In theory, since you can install the same license on multiple machines", my digest is that I can install same one license on multiple master machines. My digest is true?

[splunk_force_as]

Yes. What exactly are you trying to accomplish with multiple license masters? You could install the splunk license, for example on two hosts, and configure them both to be license masters BUT any license slaves that you configure would need to point to one or the other, not both. OR if you are looking for failover capabilities, you could try to put a load balancer in front of the two license masters (as an example). Depends on what your usecase is.

Got it. Thanks.
