Monitoring CPU, HD, etc

I found a package called collectd that has many plugins and a built in network layer. I think that the network layer can run on both monitored and monitoring systems where the monitoring system can write the values to rrd. I can then integrate this with cricket just like the ethernet switch stats. Hummm.... This might make a great generic sensor network......

The monitored system can use many plugins like lm-sensors and hddtemp to publish sensor data.

collectd
OneWire plugin - Publishes owfs sensor data
lm-sensors plugin
hddtemp plugin
thermal - uses procfs tree for apci measurements
rrdtool plugin

lm-sensors
owfs
hddtemp
