[mythtv-users] OT: Monitoring CPU Temperature

Take a look at www.generationd.com  there is a free script which monitors
any sensors (from lm_sensors, but also RAID controllers, IDE disk temps,
etc)  and can shutdown, send email alerts, etc...


You have to tailor the config to your needs.

Before anyone says it, yes, I checked Gossamer threads for this but
didn't see any posts that fit my situation, so I thought I'd ask, even
though it's not really Myth specific.  I figured that someone here would
have seen this.

My Myth box has been shutting down unexpectedly recently, and every time
I boot it back up, the POST screen says "CPU Fan Error; Press F1 to
resume".  I do that and it comes back up.  Once it said that and "CPU
Over Temperature error".  So I'm thinking that my CPU fan is having an

Before I go and buy a new one, a friend suggested that I try and monitor
it and I immediately thought "lm_sensors".  So I got that up and running
and have a few questions:

1) I know that I can run 'sensors' to get the information, but I don't
know what to do with it.  I read the docs on the lm-sensors site but
couldn't really see anything on this.  If the temp gets too high, can I
shut the box down gracefully?  Can I somehow send out an email alert or

2) I couldn't find a sensors.conf for my motherboard (an ASUS A8N32-SLI
Deluxe) on their website, but I did find one that someone made for that
board, and I'm using it now (after running 'sensors -s' to load it).

3) I ran 'sensors -f' and I see the following output (I'm not really
sure if these values are good or bad, or if I should be alarmed):
Adapter: PCI adapter
temp1:      +165F
temp3:      +162F

Adapter: ISA adapter

+5V:       +4.89 V  (min =  +4.76 V, max =  +5.24 V)

Thanks for any help or information.

If you're inclined to monitor and get alerted to information like this,
might want to look into using an NMS tool. I like OpenNMS myself, use it at
work, etc. You'll need to spend some time figuring out how to get your SNMP
agent (most likely net-snmp) to give out that kind of information but if you
want the ability to listen to traps or poll info and alert based on
thresholds this is the way to go. It can also help out for things like
monitoring for failed drives in RAID arrays, that sort of thing. I don't use
one at home myself because its just TV.
