I would recommend it to others. I am an active member of the Nagios Core community and post my updates regularly. I have managed over ten successful integrations with big government projects and private companies using Nagios Core. It works well to manage large environments and provides robust monitoring solutions. I'd rate the solution seven out of ten.

The functionality in Nagios Core is limited compared to the enterprise version, Nagios XI. If I ever need a free tool that offers similar capabilities to Nagios, I would choose Zabbix because it provides all the features in one tool. While both Nagios and Zabbix have their own strengths, some vendors specifically require Nagios for monitoring. In those cases, Nagios Core fits in quite nicely. I have previously spun up versions of Nagios Core in the cloud on AWS and Azure to test and explore their capabilities. Additionally, I have been able to automate deployments using Ansible. Integration with a third party is easy. I recommend the solution. Overall, I rate it an eight out of ten.
We receive timely alerts for any breakdown or shutdown. Without them, we wouldn't know about issues until users complain. With Nagios' alert system, we receive notifications before users even notice a problem. I highly recommend it to system administrators and network administrators. Nagios Core makes life easier with email and SMS alerts, ensuring you stay informed and can address issues promptly Overall, I rate the solution a nine out of ten.

I rate the solution an eight out of ten. The solution is good, but the initial setup process could be easier. I recommend the solution to users who want a more diverse environment for monitoring.
This solution can meet basic requirements. If someone is using it on a larger scale they might have difficulty managing it. I rate Nagios Core a seven out of ten.
When considering Nagios Core you should consider how many servers, firewalls and routers you need to monitor. Then determine which services need to be monitored by Nagios Core and how many service alerts are needed so you can create clusters and keep your gig size and RAM size accordingly. I would rate Nagios Core a 7 out of 10.

My advice to anyone considering using Nagios Core is, from the data center point of view you should try & deploy Nagios Core especially when you need an end to end, full functional monitoring system, but organizations doesn't want to spend too much in 24x7 monitoring system. Nagios is really very good from that point of view. If you are paying, Nagios XI is good. If you don't pay, Nagios core is also good. But Nagios Core needs more expertise. You need to put too much effort into configuring different kinds of services. Installation is straight-forward. I don't have any advice other than that Nagios Core is a starting point for everyone to learn data center monitoring systems. I bought Nagios XI just because certain organizations wants to manage it at their own. Else, I would strongly recommend Nagios Core only. One a scale of one to ten, I would give Nagios Core a 10 out of 10.

We're just customers and end-users. We don't have a business relationship with Nagios. We're using the latest version of the solution. We're still in the early days in terms of usage. We're still feeling the solution out and testing it for its acceptability within the greater framework of our organization's requirements. We're looking to test it at the point of sale to see how successfully it operates. Overall, I would recommend the solution to other organizations. I would rate the solution eight out of ten.

I would recommend it for small network deployments or if you have other open source applications or other metrics like utilization, CPU. So if you're running alongside other open source applications and in the small space, it works. But anything beyond that is not recommended. I would rate Nagios Core a six out of ten.

In terms of advice, I'd say that you need to know what the plan is and try to understand from which direction you are going to monitor. And, to understand what additional things you'll probably want to do from your side, like putting in scripts and other kinds of automation. So the planning is everything. If there is a particular tool you want to integrate with those things have to be properly planned beforehand. With the number of features that it has and the ease of integration, I would rate the solution somewhere close to nine out of ten.

I would rate Nagios Core as seven out of ten because it was hard to configure and the implementation process itself took about two weeks. Also, the UI is not friendly. Other products have features that aren't included in Nagios Core. I think that one was the easiest to restore. Also, Nagios supports only Linux, not A/UX. It can't be installed on the servers. If they supported all of these things, it would be much better.

We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it. That is something that we wrote and implemented as a plug-in. I would rate this solution a nine out of 10 because it's relatively easy to implement and the cost is great, it's free. My advice would be, save yourself a lot of time - go get it and install it.

There are thousands upon thousands of plugins. This is a winning product. Nothing can match the plugins, even I have contributed about six plugins.
