Ill take a look at the parser. I have heard others complain but your the first to provide output.

[ohadlevy]

lucky me ;) thanks @logicminds

[logicminds]

What version of freeipmi are you using?

[logicminds]

So I am assuming the output you posted is from the result of the same command rubyipmi used. If it is this looks to be a vendor issue with sensor data. If you look at my fixtures, which is what I based the parser on the output is different and provides much more detail: https://github.com/logicminds/rubyipmi/blob/master/spec/fixtures/freeipmi/sensors.txt

Can you run the sensor command again without the flag (--no-header-output) so I can see what your system is returning and which headers are for which sensor?

[logicminds]

I created a new branch: https://github.com/logicminds/rubyipmi/tree/gh-37 and added some unit tests that parse the output you provided. The parser seems to work as is, but I am wondering if the output you provided is different than the output given by freeipmi somehow.

You can test this out on your system by checking out gh-37 branch and running bundle exec rspec spec/unit/freeipmi/sensors_spec.rb
