Nagios Support Forum

Hello support,

we installed a new plugin for monitoring a DELL Blade Chassis. It's an official Plugin for Nagios XI from DELL (s. https://www.dell.com/support/article/de ... xi?lang=en).

To meet the prerequisites, we would need to update python and install some additional software:
Is it safe to do that? We are running a Nagios XI VMware image:

I think you should be fine but I would suggest testing on a lab XI first. The XI license allows you to have up to three installs - a production, a lab, and disaster recovery machine.

That said, I would highly recommend migrating to a new OS if possible. Cent 6 is pretty old and a lot of updated packages are not available for it which means you'd need to rely on source installs or rpms outside of the standard Cent repos. Cent 6 for example doesn't seem to have an official Python 2.7.5 package but Cent 7 does.

Ok, thanks. What steps do you recommend to upgrade to a new OS? As said before we're using the virtual appliance and did a lot of customizing....

Is an inplace-upgrade possible?

An inplace upgrade isn't possible at least when going from 6 to 7. You'll want to install the same version of XI on a 7 machine and then migrate the configuration over using the steps in https://assets.nagios.com/downloads/nag ... ios-XI.pdf. This will migrate the databases and configuration, but you'll need to manually copy over any custom plugins that were installed(usually under /usr/local/nagios/libexec) and install any third party packages that they may require - the Oracle or VMWare plugins for example rely on third party SDK's and clients that XI does not install automatically.

Hello,

thank you for your reply!

I think, we will plan to migrate the nagios installation to a newer CentOS version. I have two further questions:
1. What about CentOS 8? If we have to start with a fresh install anyway, I would prefer to start with the latest release.
2. Can we use the VMware OVA of XI? What CentOS version do you ship with that?

Best regards
Christoph

The current OVA uses Cent 7. The next XI release(5.7) will support Cent 8. I'm not sure if the OVA will also move to 8 right away, but I would suggest going with 8 on a XI source install - https://assets.nagios.com/downloads/nag ... -Linux.pdf.
