Infrastructure Analyst at a tech vendor with 10,001+ employees

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.

Automation has transformed daily operations and supports secure, continuous infrastructure

When considering improvements to Red Hat Enterprise Linux (RHEL), I see one primary area. Within your portal, if you provided more study material along with demonstrations similar to the sessions we are attending, which feature a user-friendly guide, you could incorporate this into your Red Hat console. When I want to install an agent or something else, typing in the console should provide me with clear step-by-step instructions. Throughout the years, installation steps have been available, but regarding AI agents or Ansible automation, I need to verify whether clear information exists. Including this information would be beneficial. Additionally, if you add the sessions that have occurred to your portal or another location, this would help us review them multiple times to gain better understanding. Time is limited, and many sessions occur simultaneously, making it impossible to attend everything. Making these sessions available on your website would be very helpful.
