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.
UK
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

"The solution is quite efficient."
"I would rate the overall solution ten points out of ten."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"Dashboard provides monitor of total assets."
"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."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"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."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The alerting mechanism in Nagios Core could be improved."
"t was a little hard to get our setup represented in the configuration."
"There is room for improvement in the graphics."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The user interface could be more interactive because it is pretty basic."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"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

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Most the plugin features are free."
"The product is cheaply priced."
"The solution is expensive."
"It's free."
"We are using the free version."
"It's free."
"We are using the open-source, unpaid version."
"Since it's open-source, there are obviously no licensing fees. There are additional operational costs, like the cost of hosting it somewhere."
