Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Senior Systems Administrator, Technical Lead at Connectivity Wireless
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 poller is really good, I can easily implement new stuff and it is scalable."
"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Extensibility is good as this makes it easy to write checks on your own."
"Dashboard provides monitor of total assets."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"Nagios Core is very configurable. Whatever you want, you can do it."
"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, just with a different interface, and the majority of everything there was beneficial."
 

Cons

"I believe Nagios Core will need to provide an option for big data platforms in the future."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"Nagios' great customizability is also one of its greatest drawback."
"The scalability needs improvement, it's not scalable at this time."
"t was a little hard to get our setup represented in the configuration."
"The dashboard should be improved."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Our network is made up of a lot of Cisco devices, and it needs improvements."
"I didn't care for the role-based, permission-based options, which were not the best."
 

Pricing and Cost Advice

"Nagios Core is free to use."
"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."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
"It's free."
