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.

Offers user monitoring and Internet insights and include customer journeys
It’s evolving; I feel it needs more holistic integration. It needs more improvement. It’s very good, but the integration can be slightly complicated on different platforms. I used it for a healthcare organization, and the integration was slightly challenging. In future releases, I would like to explore AI capabilities. AI would be more valuable because it works across different cloud and server systems. It looks into issue detection and insight modeling, so that is something I feel will be very helpful in the near future. More AI because of compliance and other challenges, not because of the product challenge. It’s about regulations, and we have HIPAA laws in the US and many different kinds of laws. Because of that, these specific elements and certain units don’t allow the tooling system to be fully utilized. We also support a certain segment of healthcare, which is the army healthcare segment, which is more government-controlled. There are certain restrictions in moving into the cloud. That’s where I thought those elements might need some more improvement. Also, looking into how we’ll be able to use more data visualization. It has it, but it doesn’t give you everything. If you look into the elements of use and so many other elements are there, but the UI/UX also has to be improved a bit, I feel. From a developer’s standpoint, it’s very easy, but from a consultant’s standpoint, there can be more enhancement, like one-click view and one-click report generation. Those things should be more seamless.
