Focused on stronger onboarding, networking tools have supported automation labs and faster troubleshooting
There are scenarios where Fedora Linux can improve and some features which could be better. Better enterprise VPN compatibility would be beneficial. VPN onboarding could be smoother, as Cisco AnyConnect, SecurID client, and Zscaler, Palo Alto sometimes feel less polished on Linux compared to Windows or macOS. Fedora Silverblue is improving this with immutable systems, but standard Fedora Linux could benefit from snapshot recovery and graphical user interface recovery tools. Battery optimization is another area for improvement. On laptops, I have observed that Windows or macOS often still outperform Fedora Linux for battery efficiency and sleep consistency. Corporate onboarding tooling could be enhanced. If there were easier integration for MDM and SSO onboarding, it would be a good addition for networking engineers and others from the engineering field. If AI-assisted troubleshooting were built into terminals or tools, Fedora Linux could help achieve faster mean time resolution and DNS failure reason or firewall block detection. For my role, I would prioritize better VPN, easier rollback, better enterprise integration, and more polished network troubleshooting user experience using AI-assisted troubleshooting.

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.
