NAmpel is a daemon for visualizing the state of a network using Nagios and a set of status LEDs attached to a parallel port.
NAmpel is the 'Nagios Ampel Project', started by me to keep a closer eye on my net.
Nagios is an open source host, service and network monitoring program. 'Ampel' is the german word for traffic lights, which is the intended hardware part of this project.
NAmpel will resemble traffic lights, indicating the state of affairs by means of three lights.
Green: everything is ok, no need to check Nagios.
Orange: there are at least one warnings from Nagios. Better take a look.
Red: One or more services are in 'critical' state. Panic.
The project was inspired by an idea once published at the Nagios website. There was an image of a device doing just the same and the announcement, it would be published as soon as it was ready.
The software part is a Perl script, checking the 'Tactical Overview' of Nagios at certain intervals and writing the results to the parallel port. It uses four bits to do so: Bit 0 for the green, 1 for the yellow and 2 for the red light.
Finally a fourth light (I chose blue) is available as a 'heartbeat' signal, flashing once every second to show the daemon is still running. Detailed instructions how to build the hardware part will be available at my website soon. soon. It is derived from a project which can be found at: easy-mod (in german).
What's New in This Release:
· There is no longer need to edit the script itself, since there is a decent configuration file and handling of default values.
· Debugging also becomes significantly easier with the brand new debug configuration directive.
