Reliable platform has supported long-term on-prem deployments and predictable OTA updates

If I consider how Debian can be improved, it could be more accessible in making newer software versions available for users who need recent features while still maintaining default stable behavior. While backports help, the workflow could be streamlined. The release cycle can feel slow for rapidly evolving tools, and better guidance around mixing stable, backports, and testing would help. Regarding hardware support, Debian can be improved by supporting multiple BSPs, making it more versatile in the embedded domain. Hardware support for new devices can sometimes lag behind, which is understandable given Debian's focus on stability. Clearer guidance on handling newer hardware or firmware would be beneficial.

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.

"Debian offers the best features in that it is open source, simple, and battle-tested, with a good release cycle."

"The best features Debian offers are that it is fast, simple, and long-term supported."

"Debian has positively impacted my organization by bringing strong security and consistent compliance awareness."

"The best features Debian offers are its low weight, lightweight architecture, and faster response to services."

"Debian has been a very reliable and stable foundation for all the systems I have worked on, and its package management, transparency, and predictable updates have been extremely helpful, especially for embedded and production environments."

"Debian has positively impacted my organization in that most of our applications are running on Debian."

"Debian's stability helps me in my daily work because my work relies on stability; I'm trying to deploy production workloads, and Debian offers that stability for me."

"Debian offers excellent stability and reliability as its best features."

More Debian pros

"The best features of Nagios Core on CentOS are complete infrastructure monitoring and real-time alerting and notifications."

"Nagios Core on CentOS has positively impacted my organization because it is an open-source tool that has been very useful in monitoring different services using both custom plugins and the default plugins it provides."

"Nagios Core on CentOS has impacted my organization positively because it is impactful to the business, and if the production server is down, Nagios Core on CentOS will check certain services, which impacts production."

"Using Nagios Core on CentOS had a significant positive impact on the organization at Infosys where I used it by improving system availability, reducing downtime, and enabling proactive issue resolution."

"Nagios Core on CentOS has positively impacted my organization by being very helpful budget-wise, as we rely on open source due to budget constraints for each division."

"Nagios Core on CentOS is not just a technical tool; I feel that it helps the business grow a lot by reducing downtime and improving visibility."

Cons

"What keeps it from being a perfect score is mainly the slow access to newer software and hardware support, as well as documentation that is somewhat fragmented for advanced use cases."

"It seems there should be a more deterministic way to do that. It does seem that you are running a lot of random install scripts to install things or relying on another two or three package management services, so there could be better software installation methods."

"Customer support for Debian has been acceptable. We approached the Azure Debian support, and while it seems adequate, they need to improve somewhat."

"I cannot say that I have seen a return on investment with Debian because I am a DevOps engineer, and it is my job to do this."

"Debian should have a reset feature; if something goes wrong, such as when I have installed or modified any root file, there should be a reset feature to restore my initial default settings."

"The stable kernel because it is going to be older and naturally stable does not always support brand new components such as CPUs or specialized GPUs out of the box, which can make it difficult to use there."

"In terms of scalability, Debian on-premises is not very scalable because it depends on your hardware."

"There are certain areas where Debian can definitely improve, particularly in restricted access privileges for certain aspects."

More Debian cons

"To improve Nagios Core on CentOS, I believe that many more plugins could be generated by the Nagios organization, such as those for monitoring services of an F5 load balancer or different other hardware devices such as Imperva WAF."

"Nagios Core on CentOS could be improved with an official Docker image from Nagios Core."

"Why I took off one point is that I think it is better suited for a small or medium setup."

"Regarding features, I have tried the application monitoring feature, which is not that great but still useful; for open source, it is very helpful, though there are improvement areas in the application side."

"Nagios Core on CentOS is not stable."

"Nagios Core on CentOS is very stable and reliable, but it can be significantly improved in terms of automation, scalability, and usability."
