</div>Attached is a simplified ipmi-fru that you can hopefully use to extract<br>
the FRU information you seek. "gcc ipmi-fru-example.c -lfreeipmi" is<br>
all you need to do. I took out a lot of stuff, and there a number of<br>
special cases not handled. It may not work for all motherboards, but is<br>
a good place to start.<br></blockquote><div><br>awesome, thanks a lot Al!<br>I'm starting to see the light, though I've not yet read the code thoroughly...<br><br>I just have to check (maybe with libdetect) how to identify PSU, but I already got the following data by modifying ipmi_fru_parse_open_device_id() to specify a known PSU ID:<br>

As for sensors, I figured you would probably want to use<br>
libipmimonitoring, since it's at a much higher level. I would suggest<br>
looking at the ipmimonitoring-sensors.c file.<br></blockquote><div> <br>indeed, that's what I understood.<br>as told above, I just got to check libdetect for PSU identification, then everything should be alright.<br>

Hopefully that's enough to get you going. LMK if you need some help<br>
deciphering the code more.<br></blockquote><div> <br>this should not be needed, but thanks for your kind proposition.<br><br>but you should probably publish this code in examples/, with a name like "simple-ipmi-fru.c" or alike, and highlight this code sample a bit.<br>
