I made a snapshot of the server, if any issues arise, i can always revert back.
That said, I ran into a few issues.
I updated from 4.2 to the current version.
Using the following:
https://assets.nagios.com/downloads/nag ... ading.html
After chown two files: check_dhcp and check_icmp and modifying the group of local/nagios/libexec/ in order to "make install".
There were no errors after checking configuration files but upon restart of nagios, 10 or so hosts showed as down, also the monitoring engine under component was not running.
Some research showed that i needed to recompile NDOUtils, i tried to download from
https://sourceforge.net/projects/nagios ... utils-2.x/ but got a funky error.
I will attempt again tomorrow or later tonight. The amount of emails from Nagios was a bit much so I'll need to try again after disabling notifications.
QQ - Is there an easy/fast way to shutdown all the alerts on Nagios while I do this?
