Hi,

GNMS (Gnome Network Management System) is an IP device monitoring tool written in Ruby/Gtk. It's based on known standards like SNMP, WMI, Syslog but also provides custom scripts checking to let users monitor almost everything. Notifications can be done using email, sound, SMS, IM or script. Homepage is at gnms.rubyforge.org (sorry I am not able to post links )

Regards,
david
