It's easy to setup and the plugins are easy to write. When we need to, the threshold is easy to change It would be nice to have a centralized client-settings management. At the moment, the client settings have to be changed individually. I've used it since 2011. The deployment of the new server…

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."
"Its an awesome product to use."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"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."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Dashboard provides monitor of total assets."
"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."
"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."
 

Cons

"Deploying an agent leaves much to be desired."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"The initial setup process could be easier."
"Nagios Core does not have a graphic display."
"This is the open source product, so it's a toolkit rather than a complete solution."
"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."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"Nagios Core can improve the graphical interface, it would make things a little easier."
