After digging through the old mailing list archives, I've got CPU utilization (idle) alerting by adding this to the default section of my analysis.cfg:
DS cpu vmstat.rrd:cpu_idl >=10 COLOR=green "TEXT=CPU Idle load
Normal at &V%"
DS cpu vmstat.rrd:cpu_idl <10 COLOR=yellow "TEXT=CPU Idle load
High at &V%"
DS cpu vmstat.rrd:cpu_idl <=5 COLOR=red "TEXT=CPU Idle load
Critical at &V%"
I then have, for one server where I want a yellow alert to go off for less than 15% CPU idle, added to that host's entry in the analysis.cfg file.

Anyone doing any alerting on graphed rrd data? Just looking for some sample of what you might be doing.
