Nagios or Icinga 2 as Monitoring System?

Question

Nagios

hi,
what is the best thing to install for yourself, Nagios or all the same Icinga2?

Answer 1

Zabbix

Answer 2

Other things being equal, Icinga is more functional than Nagios Core. But at the same time, it is more demanding in terms of infrastructure readiness.
Given the release and rapid development of Icinga Director, some of the issues of auto search and automatic system configuration are being removed. But so far only a part.
A good answer will be after analyzing the technical specifications and your resources for supporting and developing the system.
