1. Nagios 4.3.4

Can I ask your help, I installed Nagvis 1.9.3 on my Nagios Core 4.3.4, but when I tried to access. I guess there's still an issue on CentOS 7. First things first, why CentOS 7 instead of 6? Well, CentOS 6 has issues with Python updating because of yum. Yes, you can install a separate instance, but it's not fun and it can break.

this turtorial is a follow up of my nagios series.

you need to have:
a working linux box
