Q&A Highlights
Question: What is the biggest difference between Nagios Core and Nagios XI?
Answer: 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.

    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.

    Reviews from Real Users

    Nagios XI stands out among its competitors for a number of reasons. Several major ones are its integration options and monitoring abilities, as well as its alerting features.

    David P., a senior DevOps engineer at EML Payments Ltd, writes, “We use Nagios as a network discovery tool. We use Nagios to maintain our uptime statistics and to monitor our services. It has allowed us to be much more sophisticated in our monitoring and alerting.”

    An IT-OSS manager at a comms service provider notes, “Nagios XI has a custom API feature, and we can expose custom APIs for our integration. This is a great feature.”
