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."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"The good thing about Nagios Core is it covers everything."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"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."
"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."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
"The poller is really good, I can easily implement new stuff and it is scalable."
 

Cons

"Deploying an agent leaves much to be desired."
"The UI is a little outdated and graphics could be displayed in a better way."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"The core version is no match for the XI version."
"Lessening the price point would be an improvement."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The alerting mechanism in Nagios Core could be improved."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"Nagios Core would benefit from aggregations if a particular server goes down."
