Pros

"My organization can leverage IDERA Uptime Infrastructure Monitor to learn more about how clients perform because the solution lets you monitor and optimize devices and apply best practices."

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

"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."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"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."

"I would rate the overall solution ten points out of ten."

"The solution is quite efficient."

"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."

Cons

"The tool needs to improve the integrations."

"It is a bit slow due to latency."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"There is room for improvement in the graphics."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
