Hi, I have release for my customers a project to interface Nagios and Cacti. Nagios does the check and store perfdata with n2rrd in rrd base. Nagios2Cacti will load Nagios configuration with Nagios::Object Perl library and load N2RRD configuration and will create the configuration in Cacti to each Nagios services with perfdata configurate in N2RRD. By the way, you can use Nagios and Cacti for their best features : * nagios to supervise, schedule, alerting * cacti to graph, reporting in sexy interface this project is accessible on sourceforge : <a href="http://sourceforge.net/projects/nagios2cacti/">http://sourceforge.net/projects/nagios2cacti/</a> Best regards, Det.
