Steve's Web Applications
RRDBar: A simple frontend CGI for the RRDTool databases. This script generates a small, basic horizontal bar graph for the current value of DSs within a RRD. It also allows you to generate a small graphic containing a numerical representation of the current value of a datasource, or the last update time. You will need the GD libraries installed for this one (visit www.cpan.org).
routers2.cgi software: Generic web-based frontend for the popular MRTG systems monitoring software.
Nagios Utilities: All plugins and agents to work with Ethan Galstead's Nagios system. Includes the NagiosEventLog agent for Windows.
