Hi,

I cannot avoid to send you a part of a mail that I have read in the beowulf 
list, we have talking about the option to use lmsensors to monitorizing the 
cluster with a cron command. Someone have said that is not a good option, so 
says:


[....]
On a system equipped with an internal sensor, lm_sensors can often read
e.g. core CPU temperature on the system itself.  A polling cron script
can then read this and take action, e.g. initiate a shutdown if it
exceeds some threshold.

The bad thing is that it does NOT give you any sort of measure of room
temperature per se, although if you have the poweroff script send you
mail first, getting deluged with N messages as the entire cluster shuts
down would be a good clue that your room cooling failed:-).  Also,
lm_sensors has the API from hell.  In fact, I would hardly call it an
API.  One has to pretty much craft a polling script on the basis of each
supported sensor independently, which requires you to know WAY more than
you ever wanted to about the particular sensor your system may or may
not have.

Alas, if only somebody would give the lm_sensors folks a copy of a good
book on XML for christmas, and they decided to take the monumental step
of converting /proc/sensors into a single xml-based file with the
RELEVANT information presented in toplevel tags like

  <cpu_temp id="0" units="C">50.4</cpu_temp>

and the irrelevant information presented in tags like

  <hardware><name>lm78</name><version>1.22a</version></hardware>

then we could ALL reap the fruits of their labor without needing a copy
of the lm78 version 1.22a API manual and having to write an application
that supports each of the sensors THROUGH THEIR INTERFACE one at a
time...;-)

[....]

What do you think?

Best regards,

Leo

Hi,

first of all, I'm sorry. It has been my fault. I didn't want to begin a flame 
war. 

The person who did it, after do an explication about the message, and I think 
that he has some reason. Howeber, I insist, please, I send the comment as a 
interesting thing. Take off all the "ranted"( ?, some comment inapropiated to 
provoke a reaction?) comments and take only the idea. Maybe it could be a 
good idea, I don't know. That's all.

Please don't take only my message, look all the message thread. My message was
http://www.beowulf.org/pipermail/beowulf/2003-October/008101.html
and the theread has the subject: Environment monitoring.

Otherwise I have so say that a lot of people that are using beowulf cluster 
are using lmsensors to monitorizing the nodes, so I think that all of has to  
to agree your job.

Thank's all.

Best regards,

Leo

I think people who want to put XML into the kernel need to be taken out
back and given a sound thrashing...  :)

Tell them to go look at the kernel interface in the 2.6 kernel (one
value per file with consistant units accross drivers) and if they don't
like that, for them to bring it up on this mailing list, or
linux-kernel.

thanks,

I think that cross-posting what could become a flame war is better
avoided.

Apart from that, I believe that if that guy really wanted something
done, he would have told us directly, or even done it by himself. We
never heard about him, which means that he isn't interested in and/or
convinced by what he proposes, and we can safely ignore him.

I don't know.  I could use a good book on XML for xmas. ;')

Obviously flame bait.  Libsensors is a decent API if it is looked into.  
Lm_sensors is the standard for hardware health monitoring in Linux.  
It's not nessesary to get in a war of words defending it's ease of 
application.  If another project works better, then of course there is 
no harm if they go with that.
