Overall Satisfaction with Nagios Core

We use Nagios Core as our core monitoring solution company-wide. We are alerted if any critical systems go offline or are exceeding thresholds set for disk usage, load average, network performance, etc. This allows our on-call staff to resolve issues before end-users are affected. It also helps us determine budget needs for IT based on age or if there is troublesome hardware.
  • Extremely fast alert notifications
  • Easy-to-use GUI
  • Not that difficult to configure
  • Configuration has to be done on the command line as opposed to a GUI-based config
  • Plug-ins can be a bit difficult to install at first
  • False positive alerts can be difficult to track down and fix
  • Critical systems' uptime has increased
  • New hardware can be budgeted for and purchased to replace faulty hardware
  • Nagios Core is supported by almost all major alerting solutions in the cloud and can be integrated easily
We chose Nagios Core over Zabbix and Zenoss because it was easier to get up and running and configure than the other two products. They required network scanning for assets and then required you to enter every little detail about the host. With Nagios Core, we just entered our hosts in a single configuration file, then added services for each one. It took about an hour to begin monitoring 25 hosts.

If you have an organization with more than 10 critical business systems, then Nagios Core is a great, free solution for monitoring. If you're looking to monitor a network or network performance, then Nagios Core is not the best choice; there are other solutions that handle that better. Nagios Core is really good at monitoring hosts and components on a host, such as a MySQL database.
