(Using CentOS 7 64-bit; XI installed manually, no special configurations).

So far our organization has only activated an installation with our license once. Does Nagios differentiate between production and test servers in any meaningful way? Are we free to use our license to activate a new installation and designate it however we wish? We want to activate a test server, but it may need to be moved to different hardware in the near future. Are there any considerations that must be made prior to moving a server? Does everything just work, so long as not more than 3 activations are running at a time, or does one need to be deactivated before the license can be used again?

Thanks.

Yes, Nagios differentiates between production, DR, and test systems. Each license gets 3 activations (prod/DR/test), see here for what a single XI license entitles you to:

https://support.nagios.com/kb/article.php?id=145

Once you exceed the three activations you will need to reach out to [email protected] (or call in) to have them deactivate/add a new activation.

Only your prod instance can be actively monitoring/alerting outside of testing/migration. After testing/migration, the other systems should be turned off or have Admin > Monitoring Engine Status > Notifications/Active Checks/Passive Checks disabled to stay within the spirit of the license.

NOTE: The DR/test systems will still need firewall rules in place and any agent allowed hosts directives would need to be updated to add the new DR/test XI server IPs otherwise the checks will fail.

The XI backup/restore process makes migrating (or cloning prod for DR/test) pretty easy:

The process is this:
- Spin up new server running a latest supported distro from the Install guide.

- Install the exact same version of XI that the old server has on the new server, no need to configure it, just install it and go through the initial setup (do not try to restore over different versions of XI you will cause issues)

- If you have a RAMDisk installed, are using RRDCacheD, or are running Mod_Gearman on the old system, set them up before restoring:

If you are monitoring vmware/oracle you'll need to reinstall the proper supporting packages on the new server again following these guides:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf
https://assets.nagios.com/downloads/nag ... ios-XI.pdf

- Backup the old/transfer to new/restore to the new

- Follow the After The Restore section from the backup/restore guide completely

- If you're changing OS versions, run the restore_repair script from the backup/restore guide:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

- Shutdown (or re-IP) the old if migrating, set the old IP on the new system so you don't have to update agent configs/FW rules

That's pretty much it.

Thank you very much for your reply! I appreciate that you anticipated what my next questions were likely to be. I didn't know about the repair script. You've saved me some time and reminded me to review available scripts. Is there official documentation just about the scripts in /usr/local/nagiosxi/scripts/ ? I didn't find what I was looking for on https://library.nagios.com/library/prod ... mentation/
