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

"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."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
"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."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"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."
"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."
"The setup is very intuitive and quick - it all just took a few minutes we were done."
 

Cons

"The core version is no match for the XI version."
"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."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"I would like to see more training videos."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"The configuration and reporting modules need to be improved."
"t was a little hard to get our setup represented in the configuration."
"It is a bit slow due to latency."
"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."
"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."
"We are using the open-source, unpaid version."

"We are using the free version."

Questions from the Community

Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
