Hi! I've managed to install pnp4nagios 0.6.3 and I'm a bit confused about how pnp4nagios generates graphics. Almost out of the box, it started graphs for ping and some http servers (not all of them). But, how can I make it graph things like disk utilization (When that value comes from SNMP)??

For example,

ls /usr/local/pnp4nagios/var/perfdata/isis/

Cola_de_Mail.rrd  Cola_de_Mail.xml  HTTP.rrd  HTTP.xml  PING.rrd  PING.xml

Those are checks running on the host isis, but there are many other checks for that server that are not taken into account by pnp4nagios. How can I make pnp4nagios "see" the other checks??

Thanks!
