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 scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
"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."
"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."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Inspite of this limitation it is a fantastic product to use at zero cost"
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"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."
"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."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"They should simplify the features so it becomes easier to setup out of the box."
"This is the open source product, so it's a toolkit rather than a complete solution."
"The interface could be improved."
"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."
"The user interface could be more interactive because it is pretty basic."
"I like to have the option to configure Nagios using the web interface."
"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."
"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 open-source, unpaid version."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is a cheap solution."
"Lessening the price point would be an improvement."
"We are using the free version."
"The product is cheaply priced."

Questions from the Community
