Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor

Ultimately NagiosXI is the better solution than Core but shortlisting NagiosXI also definitely depends on the infra landscape, technology, network devices, and other scopes of activities in monitoring. The biggest difference I see between Nagios Core and XI is the user interface, reporting, and onboarding any element for monitoring, and that onboarding is much easier in NagiosXI than Core. Nagios Core is little complicated where you have to use console called Nconf or editing conf files in Linux needs more technical knowledge than using NagiosXI.

I installed it in my AWS and Google cloud computing environments. Following the documentation explicitly, logs all indicated successful results yet neither environment was able to open up the GUI to confirm it was functional. I opened a support case which I've done with almost every product I have ever installed and was informed that I needed to have a licensed product before support could answer my questions. I just finished a project where I installed crushftp and I had a similar problem and I hadn't purchased the product. They asked me for logs and supplied a solution in short order. I couldn't suggest the product with support like that as I've spent years apologizing for HP support that was almost nonexistent.
