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

"We mostly use Nagios Core to integrate with Python and Bash Script."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"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."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Provides timely notifications."
"Nagios Core is stable."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"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."
"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 should be improved."
"The mapping is a little hard."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"There is room for improvement in the graphics."
"The core version is no match for the XI version."
"The initial setup process could be easier."
"The user interface could be more interactive because it is pretty basic."
"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."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is free to use."
"Nagios Core is a cheap solution."
"Nagios Core is an open source solution, and there are no licensing fees."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"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."
