Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Offers custom monitoring functionality, user-friendly interface, custom maps feature and open source
Based on my experience, there should be options for using the latest communication methods, like social media integration. Telegram is already integrated, but SMS and other alert options would be beneficial. So, integrating social media notifications into NetXMS would be a good thing. As a large company, we integrate different systems together. We'd like to see some improved functionalities for enhanced integration. For example, our incident management system isn't currently integrated with NetXMS. Ideally, we'd like the alerts generated in the monitoring system to automatically create tickets in our ticketing system, similar to how some other systems function. NetXMS doesn't offer this functionality itself because they are not an incident management or ticketing system vendor. They allow integration with other vendors, but our ticketing system isn't currently supported. So they recommend using it with any other application of our choice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"We can get real time statistics of our servers which improves our monitoring."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"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."
"We have a large network spanning over 1000 kilometers. NetXMS provides visibility and sends alerts. Typically, most monitoring systems monitor every 60 seconds, but NetXMS allows us to adjust this. For critical links, we can set it to check every second. For our high-priority financial customers, we monitor every second. So, every three seconds, we receive another email and a Telegram alert. This helps us meet our SLAs (Service Level Agreements) with our high-priority customers."
 

Cons

"Nagios Core does not have a graphic display."
"There is room for improvement in the graphics."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"The UI is a little outdated and graphics could be displayed in a better way."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"Based on my experience, there should be options for using the latest communication methods, like social media integration. Telegram is already integrated, but SMS and other alert options would be beneficial. So, integrating social media notifications into NetXMS would be a good thing."
