Setup Cost

Nagios Core on CentOS is popular for being cost-effective and easy to install, despite some indirect maintenance costs.
Enterprise users find Oracle Solaris pricing complex; it's beneficial for performance but costly compared to Linux, with desired pricing improvements.
The main factors that influenced my decision to choose Nagios Core on CentOS over other monitoring solutions are mainly its free of cost, open source nature, which saves a lot of money, and it being easy to install, so even junior staff can set it up straight away to start monitoring.

Featured Reviews

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.

Long-term server platform has supported secure banking operations and simplified virtualization
Oracle Solaris is a very good operating system. Most of the time, we do not need to change or replace any configuration. If at any point in time we need to change something, it is really simple and a user-friendly environment. Although it is a CLI, Oracle introduced a GUI environment with Solaris 11.5. Currently, 11.5 has the operating system GUI as well as the CLI. The technical persons working on the operating system most of the time prefer to work on the CLI. It is actually really good and easy to use. As it is a server-level operating system, most of the time you do not need any extra features in the operating system because you are not using the operating system on home machines, desktops, or laptop machines. The extra features are not needed if we are talking about the enterprise level or an official operating system.
