Nishith-Vyas - PeerSpot reviewer
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

"The solution's most valuable feature is that it offers proper alerting capabilities."
"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."
"Provides timely notifications."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"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 application performance monitoring feature is valuable."
"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."
"I would rate the overall solution ten points out of ten."
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

"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."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The tool needs to improve the integrations."
"It is a bit slow due to latency."
"t was a little hard to get our setup represented in the configuration."
"The initial setup process could be easier."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
More Nagios Core cons
"I didn't care for the role-based, permission-based options, which were not the best."
 

Pricing and Cost Advice

"Nagios Core is an open source solution, and there are no licensing fees."
"Nagios Core is free to use."
"Most the plugin features are free."
"The solution is expensive."
"The enterprise version has technical support. The version we are using is 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."
"It's free."
