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.

A network monitoring platform with a useful reporting feature, but permission-based options could be better

The initial setup is fairly easy. Most of it's wizard-based. You don't have to be a rocket scientist to set it up. But if you don't know certain things related to protocols and everything else, it might be difficult. If you know how SNMP works, it'll be fairly simple to set up.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We use the product to monitor server applications."

"It is fairly easy to set up, and we can monitor pretty much everything we want to."

"Key features include the GUI interface, its notification capabilities, and the real-time reporting."

"Nagios Core is stable."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"The most valuable feature is the performance parameters of the system."

"The application performance monitoring feature is valuable."

"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."

More Nagios Core pros

"Reporting on NetCrunch is pretty good. It's very similar to SolarWinds. It's just a different interface. The majority of everything there was beneficial."

Cons

"The tool needs to improve the integrations."

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"The interface could be improved."

"Nagios Core does not have a graphic display."

"t was a little hard to get our setup represented in the configuration."

"The user interface could be more interactive because it is pretty basic."

"The core version is no match for the XI version."

"The UI is a little outdated and graphics could be displayed in a better way."

More Nagios Core cons

"I didn't care for the role-based, permission-based options, which were not the best."

Pricing and Cost Advice

"It's free."

"The product is cheaply priced."

"Nagios Core is an open source solution, and there are no licensing fees."

"The enterprise version has technical support. The version we are using is free."

"The solution is expensive."

"We are using the free version."

"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 have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
