Overall Satisfaction with Nagios

Nagios is the industry standard for IT systems monitoring. I use it to keep an eye on all my critical systems. Pretty much every aspect of a system can be monitored with Nagios, from a simple up/down check, to available disk space, to service status, to hardware status. It allows me to identify problems before they become user-impacting.
  • Cost - you can pay for support and an easier interface, or you can get all the monitoring you need for free.
  • Extensibility - you can pick from the vast array of checks available, or roll your own custom checks.
  • Customizability - you can pick different interfaces, add in historical graphing, configure maintenance windows, and much more.
  • Learning curve - can be steep, especially for those not familiar with Linux.
  • Messy configurations - it is easy to get your configuration files into a mess without careful management.
  • Breakability - it is easy to break your configuration accidentally, and can be difficult to figure out what you did wrong.
  • Allows IT to identify problems before they become business-impacting
  • Provides greater visibility into resource usage to allow for right-sizing of systems
  • Allows growth to be easily measured for future needs forecasting
  • SolarWinds Server & Application Monitor
While SolarWinds may be much more advanced, Nagios will do 90% of what you need at a fraction of the cost.
Nagios is perfect for companies that don't have a budget for IT monitoring, but still expect systems to be up 24x7. However, if you don't have anyone on staff who has used Linux, you might have a hard time getting it up and running. It also makes a great companion to more in depth monitoring solutions.
