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

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Provides timely notifications."
"The application performance monitoring feature is valuable."
"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."
"The solution is quite efficient."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"Nagios Core is stable."
"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

"The core version is no match for the XI version."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Would benefit from aggregations if a particular server goes down."
"t was a little hard to get our setup represented in the configuration."
"The tool needs to improve the integrations."
"It is a bit slow due to latency."
"I would like to see more training videos."
"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."
 

Pricing and Cost Advice

"The enterprise version has technical support. The version we are using is free."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"Most the plugin features are free."
"The product is cheaply priced."
"It's free."
"It's free."
"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
"Since it's open-source, there are obviously no licensing fees. There are additional operational costs, like the cost of hosting it somewhere."
