Quotes from Members

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

Pros

"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."
"The Centerity gives us exactly what we need from performance system monitoring."
"The solution is very complete and mostly easy to manage."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"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 very configurable. Whatever you want, you can do it."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
"Extensibility is good as this makes it easy to write checks on your own."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
 

Cons

"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"One of the major improvements should be it implementation as a SaaS"
"The GUI must be improved. Graphs must be changed including high level maps"
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"The configuration and reporting modules need to be improved."
"It is a bit slow due to latency."
"The dashboard and monitoring features could be improved."
"The user interface could be more interactive because it is pretty basic."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
