Good end-to-end voice quality monitoring and offers valuable features
The solution should have automatic baseline detection. On the per hour, per base, per week. That's usually the best. And on a per individual CI level. I know that they're working on it and when that's available then we will definitely implement it because it will reduce the effort we need to maintain all the products. Right now we have to set thresholds for every location, and it needs to be actually dynamic so if we have better thresholding, we'll have faster alarms across all our locations. We won't have to expend effort on it by resetting or checking them on a regular basis.

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.

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Nagios Core is stable."

"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

Cons

"The solution should have automatic baseline detection."
"All the features and functions of the solution can be improved, specifically the user experience."

"Lessening the price point would be an improvement."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."

"The UI is a little outdated and graphics could be displayed in a better way."
