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

"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."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Nagios Core is very configurable. Whatever you want, you can do it."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"The solution is quite efficient."
"The application performance monitoring feature is valuable."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"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 is limited in terms of distributed setups, and there is no central view for remote data centers."
"The dashboard and monitoring features could be improved."
"The core version is no match for the XI version."
"It is a bit slow due to latency."
"The UI is a little outdated and graphics could be displayed in a better way."
"There is room for improvement in the graphics."
"The dashboard should be improved."
"t was a little hard to get our setup represented in the configuration."
"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 are using the open-source, unpaid version."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"It's free."
"We are using the free version."
"Most the plugin features are free."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is a cheap solution."
"It's free."
"Since it's open-source, there are obviously no licensing fees. There are additional operational costs, like the cost of hosting it somewhere."
