, all of the above can be solved. The implementation principle, which has been published before, is of course based on Nagios. Bottlenecks, that is also the bottleneck of Nagios, performance temporarily not outstanding, ease of use, but also can, not too much trouble, technology, can not break through the bottom of CGI

From the initial Nagios to the now powerful Zabbix 3.0, I would say that no performance-based development and monitoring are all nonsense?First of all, I am aware of these two monitoring software:Zabbix, a lot of enterprises are in use, give a person's feeling is very dazzling, but I personally think that although it
