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 good thing about Nagios Core is it covers everything."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"We can get real time statistics of our servers which improves our monitoring."
"The reporting structure and the feature set are valuable to me."
"The solution is quite efficient."
"Provides timely notifications."
"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

"Application level monitoring is limited."
"The dashboard and monitoring features could be improved."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"It is a bit slow due to latency."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"The dashboard should be improved."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"Generally, it does what I need it to do, but better error reporting would be great."
"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."

"Nagios Core is an open source solution, and there are no licensing fees."

"I would rate the solution's pricing an eight out of ten."
