Nagios Support Forum

Hi,

Nagios XI is installed on CentOS, with the ova you provide.

When I update Nagios (from 5.6.3 to 5.6.4 for example), is it updating CentOS too ?
If not, should I update CentOS before or after a Nagios update ?

Thank you

A Nagios update may install some newer packages, but doesn't do a full CentOS update.

Major upgrades would require making a Nagios backup and migrating it to the new machine(see https://assets.nagios.com/downloads/nag ... ios-XI.pdf for migration steps), but running a "yum check-update" and "yum update" can be done to keep the current OS and packages up to date. I'd recommend running it before a Nagios update.
