Pros

"Centerity is much more than a monitoring tool — it’s a unified, end-to-end, enterprise-class and multi-tenanted AIOps Platform that is purpose-built to help MSPs and data-centers deliver the highest levels of up-time and performance."
"The machine learning feature is valuable."
"The Centerity gives us exactly what we need from performance system monitoring."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"The application performance monitoring feature is valuable."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Dashboard provides monitor of total assets."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"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."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
 

Cons

"One of the major improvements should be it implementation as a SaaS"
"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"The GUI must be improved. Graphs must be changed including high level maps"
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"There is room for improvement in the graphics."
"The initial setup process could be easier."
"Lessening the price point would be an improvement."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The scalability needs improvement, it's not scalable at this time."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"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."
