Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one.

Cons

"I would like to see more training videos."
"The tool needs to improve the integrations."
"The scalability needs improvement, it's not scalable at this time."
"The mapping is a little hard."
"The dashboard and monitoring features could be improved."
"Nagios Core does not have a graphic display."
"The user interface could be more interactive because it is pretty basic."
"There is room for improvement in the graphics."
"We would like the real-time monitoring of an interface to be improved within this solution."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"I think some improvements to the Android app would be good."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
