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.

Pros

"We use the solution to meet the needs of the customer."

"Good end-to-end monitoring"

"We mostly use Nagios Core to integrate with Python and Bash Script."

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"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."

"I would rate the overall solution ten points out of ten."

"Nagios Core is stable."

"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."

Cons

"The solution should have automatic baseline detection."

"All the features and functions of the solution can be improved."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"The dashboard and monitoring features could be improved."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"t was a little hard to get our setup represented in the configuration."

"The core version is no match for the XI version."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
