Did you power it off and then try starting it up again? (maybe the wrong kernel was selected on boot or it got changed somehow?)

Were there any power outages, a non-graceful shutdown, or did a disk fill up (on the host or the esxi server)?

Can you get into the grub menu, press the e key and post what it says for all lines, you may have to hit enter on the long lines with the -> arrow on them and then hold the left and right arrows to scroll though the text. You can hit escape to go back a menu.

How was this server initially installed? Was this an OS that you installed and then you installed Nagios after, or was this a pre-built VM image that we offer?

Regardless, this doesn't seem like an issue that is entirely in-scope for this forum. We'll do what we can to help, but this sort of thing is something you should bring up with your system admin.

You don't per-chance have local or offloaded scheduled backups in NagiosXI (apart from your VM level Netbackup configuration) do you? If so the most recent of those would be the best to use.

If not - there are a lot of active locations for data. If you're not worried about historical records getting lost though - just restoring the nagiosql mysql db and the nagiosxi postgresql database should take the system back to a functional state that it was in before (provided you didn't add any components/wizards/plugins).
