Hi . Great job. My Server went down due to power surge; I realize I could not start my already configured Nagios. Do I need to start installation again or a particular service need to be started? Mind you i set up my Nagios on CentOS 07.

Hi! Tell me, I have such an error, how can I fix it. "Trying to access array offset on value of type bool in /usr/local/nagios/share/includes/utils.inc.php on line 217".
I have it installed on ubuntu 20.04, php version 7.4. I really need your advice

[@ballamoussadoumbouya8175]

For the supervision of the bandwidth which sorts at the level of the interface of your router, why did you take the information from the MIB of ifOutOctets.1? why you didn't take for ifOutOctets.2 or for ifOutOctets.3 for example? thank you for explaining to me please

[@yaznelita1]

because it originally defined interface 1, you can work with variables from interface 1
