I'm using the official debian packages. I'm running debian testing but I 
installed the collectd package (+ collectd-dbg) from sid since there are 
no dependencies issues and it's the last version.

I installed the collectd-dbg package and enabled the "LoadPlugin 
logfile" entry ecc... Nothing useful, just this output:

root at vulcano:~# collectd -C /etc/collectd/collectd.conf -f
[2008-03-18 21:05:23] cpufreq plugin: Found 1 CPU

I found this taking a look at the /etc/init.d/hddtemp script:

"if /usr/sbin/hddtemp -wn $OPTIONS $disk 2>/dev/null"

and from the hddtemp manpage:

-w, --wake-up
               Wake-up the drive if needed (ATA drives only)

Maybe this keeps drives active. I'll try to change it.
By the way, did you receive the other mail about this issue?

Ok, so:
- sensors problem --> solved soon
- hddtemp  --> not a collectd problem (however I'll try to use a script 
for collecting hdds temp data as well)
- ping not working --> still a mistery

On another machine running ubuntu, with both collectd and collectd-ping 
3.10, ping plugin works fine... it's a little bit strange.

However thank you for your help!
