Is it possible to have multiple license managers behind a load balancer?

I wasn't sure if having multiple different license managers would cause any violations. Ideally we really do not like the idea of having a single point of failure for our license manager, and are looking to implement redundancy. Is this possible or will it cause issues?

I suspect multiple LMs will cause issues.

There's no real need for more than a single LM. If the LM goes away, the clients will continue to function normally for a few days - which should be more than enough time to stand up a new LM.

Hi @briancronrath ,

as @richgalloway said, License Manager, as the other Splunk management consoles aren't Single Point of Failuer because the infrastructure will continue to run even if the License Manager is down.

You eventually can have a turned off copy in a disaster recovery site, if the down is longer but it isn't mandatory.

Ciao.
