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

"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."

"The solution's most valuable feature is that it offers proper alerting capabilities."

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

"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"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."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"The reporting structure and the feature set are valuable to me."

More Nagios Core pros

"The setup is very intuitive and quick - it all just took a few minutes we were done."

"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

"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."

"The UI is a little outdated and graphics could be displayed in a better way."

"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."

"It is a bit slow due to latency."

"The dashboard and monitoring features could be improved."

"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."

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

"The alerting mechanism in Nagios Core could be improved."

More Nagios Core cons

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

"Our network is made up of a lot of Cisco devices, and it needs improvements."

Pricing and Cost Advice

"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."

"Nagios Core is a cheap solution."

"We are using the free version of Nagios Core."

"The solution is expensive."

"It's free."

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

"We are using the free version."
