I advise others looking into using Nagios Core on CentOS to choose it for strong infrastructure monitoring if they want reliable alerting, and if they want on-premises or hybrid cloud, both are supported by Nagios Core on CentOS. There is also a low-cost solution and custom monitoring data, and it works for both data center and enterprise infrastructure. If these features are needed, I will advise using Nagios Core on CentOS. Nagios Core on CentOS is a good product and has enterprise support, so I believe it is a solid and reliable monitoring tool. However, it belongs more to the traditional infrastructure monitoring world than to modern cloud-native observability. I believe Nagios is working on that, so in the future, it will support hybrid cloud-native applications as well. I give this review a rating of ten out of ten.

If you are considering Nagios Core on CentOS, then treat it as a powerful but hands-on tool. You will get great reliability and flexibility, but you need to plan for setup, automation, and maintenance from day one. For a mid-size or small size infrastructure, Nagios Core on CentOS is a good option; for a large infrastructure, consider other tools. I rate this product as a six out of ten.

My advice for others considering Nagios Core on CentOS is to focus on cost savings since organizations globally are cutting costs. My additional thoughts on Nagios Core on CentOS include that certain metrics could be improved or added; however, ninety percent of them are already available. I would rate this product an eight out of ten.
My advice for others looking into using Nagios Core on CentOS is that it is good, but we should set only one page for the services and disk devices. I would rate this product an eight out of ten.
