Quotes from Members

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

Pros

"It's easy to setup and the plugins are easy to write."
"The good thing about Nagios Core is it covers everything."
"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."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"The solution is very complete and mostly easy to manage."
"Extensibility is good as this makes it easy to write checks on your own."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
 

Cons

"Deploying an agent leaves much to be desired."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"The user interface could be more interactive because it is pretty basic."
"The mapping is a little hard."
"Generally, it does what I need it to do, but better error reporting would be great."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"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."
"Nagios Core does not have a graphic display."
"Nagios' great customizability is also one of its greatest drawback."
