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 most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"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."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"The most valuable feature is the performance parameters of the system."
 

Cons

"Deploying an agent leaves much to be desired."
"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 scalability needs improvement, it's not scalable at this time."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"Nagios Core does not have a graphic display."
