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.

Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"Good end-to-end monitoring"

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"The solution is quite efficient."

"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."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"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."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

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