Use Cases and Deployment Scope

Currently we are not using Nagios, but we did for about 8 years, and I loved working with the software. We monitored servers, Netapps, switches, power, temperature, site up-time, application monitoring, revenue graph alerts, and we were just starting to use the integrated graphing. The only departments that used Nagios were Systems, NOC, and our developers.

Pros and Cons

Readability: Monitoring screen is very easy to read and there are several other views that are very helpful as well.
Easy of setup for new devices
Reporting: Reports are accurate and easy to update using group settings
Training is simple. Technicians are up and running in about 15 minutes.

A GUI would be nice
Being able to turn off monitoring a device for a period of time (removing the device from the screen)
Database driven configurations
