Monitoring has reduced outages and improves proactive issue resolution across our infrastructure
Regarding complexity, I think there is no feature like InfluxDB AI, so it may require more expertise to configure. There are also some migration challenges in adopting the new dashboards, so it takes some time to train the staff, but it is not a big concern. I think it is better to add some advanced features. I do not think there are so many things that need to be improved in Nagios Core on CentOS. If it is better to customize the dashboard or if we can get something like a modern view, it will be helpful for the dashboard. I felt very happy with Nagios Core on CentOS. Why I took off one point is that I think it is better suited for a small or medium setup. If large enterprises can use Nagios Core on CentOS, it will be helpful. It also requires manual editing of the config file, so it is a little bit time-consuming. The web interface is functional, but compared to some other latest AI monitoring platforms, it is a little bit lacking. I think the AI platform would score higher, but it is good. The reporting is just basic, so if we compare it with Grafana, it needs richer insights.

Has supported secure application hosting and reliable server management
I find the GUI to be good in Ubuntu Linux, and I appreciate the open SSH. The fact that it is free since it is open and open-source is why I appreciate it and feel it is secured. We have multiple different kinds of support related to Ubuntu Linux, including official support and other options. I am currently using laptops, desktops, and servers, and Ubuntu Linux supports all these devices. If I need it for Raspberry Pi or something similar, I can download another Linux distribution. Ubuntu Linux is scalable, especially for servers. We prefer using Ubuntu Linux Servers rather than Windows. The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable.
