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."
"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."
"We use the product to monitor server applications."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"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."
 

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"
"It is a bit slow due to latency."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The initial setup process could be easier."
"The tool needs to improve the integrations."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
