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outdated and no longer being maintained: xmbmon, healthd, lmmon,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.
