Nagios Support Forum

Hello,

As far as I understood the Nagios License includes the installation of one Master Server, one Slave Server and one Test Server. My questions are:
- How can we test, during the Trial, this Redundancy (Master and Slave Server)?
- How do we install this Redundant Server?
- Is there any Failover, Redundancy, Failback or High Availability solution we can configure, out of the box or that is pre installed in Nagios XI?
- If there isn’t, do you have, some sort of Guide or Procedure, we can follow to implement this?

Thanks

The Nagios XI license allows three instances, but the relationship between them is not exactly that of master and slave. They are separate installs that allow you to test updates and changes before you implement them in production. Please follow the link below for more information on what a Nagios XI license entitles you to.

As for achieving high availability with Nagios XI, I recommend you follow the document linked below.

I hope that helps! Let me know if you have any more questions.
