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.

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

"Provides timely notifications."
"Nagios Core is stable."
"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."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"The most valuable feature is the performance parameters of the system."
"The application performance monitoring feature is valuable."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"Nagios Core is very configurable. Whatever you want, you can do 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

"There is room for improvement in the graphics."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The tool needs to improve the integrations."
"I would like to see more training videos."
"The interface could be improved."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"It is a bit slow due to latency."
"The scalability needs improvement, it's not scalable at this time."
"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

"Most the plugin features are free."
"It's 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."
"We are using the free version of Nagios Core."
"The solution is expensive."
"I would rate the solution's pricing an eight out of ten."
"We are using the open-source, unpaid version."
"We are using the free version."
"Since it's open-source, there are obviously no licensing fees. There are additional operational costs, like the cost of hosting it somewhere."
