Yes, our organization uses Nagios [Core] to monitor all infrastructure and it works finely in a diverse environment. It has very good documentation from implementation to monitoring and web interface, as well as a very good easy-to-navigate icon. The host and service can be organized to manage the host and client easily.
  • Network analysis
  • Effective data collection
  • Easy implementation
  • Web UI should be better while navigating
  • Improve security
  • Need to extend support and availability
So the Nagios [Core] gave us valuable features like report analysis and graphical structure, so it will easily evaluate and track the issue. Also, the email function is very useful, so we get informed at very crucial times with findings, and also generate templates for popular endpoints which make it very better.
  • Network analysis
  • Open source
  • Calculated data
  • Open source is helpful.
  • We have better managed downtime due to calculated data.
  • No negative impacts.
  • SolarWinds Network Performance Monitor (npm)
Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

We use Nagios as our alternative Network Monitoring Software for our data centers and out branches. It helps you monitor branch with down wan links so that you can escalate it to [your] internet provider. Also gives you historical reports per device that helps you evaluate and track ups and down of servers or network equipment.
  • Network Monitoring
  • Reports generation
  • Freeware
  • Develop interface to look professional
  • Gives more detailed report
  • Add monitors and sensors compatibility
For us, we use it just [as] a backup for our main Network Monitoring Systems since it only uses ICMP to monitor the device. If you are looking [for] in monitoring devices using SNMP that will provide you auto discovery and details of your device, Nagios is not for you. But as a backup platform, it is a great tool.
  • Device monitoring
  • Historical reports
  • Backup platform for network monitoring
  • Real time monitoring by using ICMP
As a backup NMS, it is better to invest to Nagios since it costs less than any other competitors which [provide] the same level of service. Maybe PRTG gives more features but you don't need all [those] features for your daily use so Nagios gives you what you need when it comes to monitoring.
