Hi Bernard,
I am going to try to answer your question. I assume you are talking about Intel AMT and PET events related to it. In general, Intel AMT eventsare only very loosely based on a subset of IPMI. The specific subset has never been documented to my knowledge. So, if you go in the IPMI documents, there are plenty more sensors & functionality defined that is not present in Intel AMT. Additionaly, you can't change any of the sensor settings, they are all hard coded. The only thing you can change is the event filters used to log and subscribe for PET events. So, basicaly, what you have is what you get.
There are only very few "sensors" or event sources in Intel AMT: "Unspecified", "BIOS", "Disk", "Addin card", "Processor", "Intel AMT". I think that's pretty much it. I suggest pulling down the event log from an Intel AMT machine and go from there. I would not rely on the IPMI specification too heavily.
I am not familior with "SDRR". But I hope this helps,
Ylian
