Nagios Support Forum

I am about to update the OS for our Nagios XI VMware appliance for the first time. Is there a proper procedure that I should follow documented somewhere? I have been unable to find it on the Nagios website and on this forum.

Let me know, thank you in advance!

CentOS does not have an upgrade path. If you are moving from CentOS 6 to 7, you will need to migrate using the Backup/Restore procedure: https://assets.nagios.com/downloads/nag ... ios-XI.pdf

If this is RHEL, I think the limitation still exists, but you're better off asking Red Hat about that, and I assume you are talking about the OVA you downloaded from us.

CentOS 6 still has support for a couple of years. You could just wait to upgrade. yum update should get you the latest security fixes.

Correct, I am talking about the ova I downloaded from Nagios Enterprises.

I will obviously run a Nagios backup and take a VMware snapshot prior to the update. I just wanted to make sure I was following proper update procedures prior to running the OS update. Would you recommend that I stop all the Nagios services prior to the update or just leave them running during the yum update process? Is there anything else that I should consider or take into account prior to running the OS update?

Thanks for your assistance!

If all you are doing is yum update and not a move from CentOS6 to 7, then things should be fine. I run yum-cron myself, and have never run into any issues. Of course, taking a backup is a good fail safe.

The caveat to the above is that if you have any custom plugins (or components) that use specifics in a version of perl/php, we can't say anything about those. However, Red Hat (and thus CentOS) try very hard not to break things.
