If you have your Nagios monitoring server published on the public Internet and have administrators working from home or have engineers oncall for troubleshooting then you can better off with the following iPhone applications to keep you upto date on whats going on with your network (I’m assuming you are all those rich administrators with iPhones hanging in your pockets).
Just came across this great Firefox Browser addon, Nagios Checker 0.11 for Nagios Network Monitoring system alerts. This is a great simple addon that shows any alarms on your nagios monitoring system simply on the browser status bar providing the need not to logon to Nagios web interface. The extension loads up in the status bar and alarms you of any network events. What I liked in the extension is that it is absolutely non-intrusive. Sits on the bottom right corner of the browser status bar and highlights any alarm. When you move your mouse over it, it displays the alarm in detail.
Nagios® is an Open Source enterprise grade host, service and network monitoring program. Nagios is a host and service monitor designed to alert network problems. Nagios is designed to run under linux but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external “plugins” which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser.
