Please, enlighten me which of these several tools were updated in the 
last few years. Most hardware monitoring tools in the ports tree are 
outdated and no longer being maintained: xmbmon, healthd, lmmon, 
consolehm, wmhm etc. Several of these have a last-modified date of 2000, 
that's 7 years ago!

Please note that this framework is not limited to monitoring temperature 
and fan speed sensors -- it also allows one to monitor raid array status 
and a few other things.

Moreover, in OpenBSD and NetBSD these kinds of in-kernel frameworks are 
used to display ipmi(4) sensors, too.

Monitoring of remote machines with this framework is also possible -- 
with symon from ports.  Querying local machines is as easy as running 
sysctl or systat, and alerts can be generated through sensorsd.

Cheers,
Constantine.
