Quotes from Members

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

Pros

"The Centerity gives us exactly what we need from performance system monitoring."
"The machine learning feature is valuable."
"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."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"I would rate the overall solution ten points out of ten."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"Nagios Core is very configurable. Whatever you want, you can do it."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
 

Cons

"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"
"One of the major improvements should be it implementation as a SaaS"
"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."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The alerting mechanism in Nagios Core could be improved."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"t was a little hard to get our setup represented in the configuration."
"They should simplify the features so it becomes easier to setup out of the box."
"It is a bit slow due to latency."
