Hi all

I add the sensor in entity-manager config like below

I use the busctrl command to see MB_P5V_SB information, it is normal.

But I use "ipmitoo sensor” command, it return the error information below as
MB P3V3          | 3.271      | Volts      | ok    | na        | 2.947     | 3.046     | 3.511     | 3.596     | na

Please give me some advise.

Many thanks

Hello,

What is your question exactly?
If it is about precision, then you should take in account that IPMI use
8-bit variables to represent values and some coefficients which
calculated based on MinValue/MaxValue parameters of corresponding
Sensor interface.
You will never get exact values in IPMI, unless you values can fit to
8-bit integer.

Hi Andrei

My question is that I set MB_P12V "upper critical" is 13.23, "upper non critical" is 12.6, etc .
When I login web page, I can see the setting what I want. 
But when I use “Ipmitool sensor” command, the response is wrong. Like below

MB P12V          | 7.215      | Volts      | ok    | na        |6.386     | 6.723     | 7.429     | 7.829     | na 

I am not sure am I miss something.

Thanks
Paul

ipmitool uses SDR records to calculate how to translate the 8-bit sensor 
reading into a value in range.

For intel-ipmi-oem the SDRs are generated on the fly, with most being 
Type 1. The Type 1 has a M, M(B), R, and R(B) value that is calculated 
from the values in the JSON. The code inside this section uses several 
of the entries in the JSON to generate the M and R values.

We were recently bit by this calculation, because the calculation used 
the "worst case" values of reading(min), reading(max), UC, and UNC, and 
combined them for the M and R.

Somehow the UNC and UC values were outside the reading range, and the M 
and R values were calculated in a way that made the sensor output 
incorrect as displayed by ipmitool.

You may want to investigate if the SDRs are correct. Use 'impitool sdr 
dump sdrs.bin' and find the SDR for the sensors of interest and see if 
the M and R values are sensible.

If they aren't find the code generating those values and identify how 
the values are created. Adjust your JSON as necessary.

Hi Johnathan & Konstantin

Thanks for your explanation. It is very helpful to me.
I adjust the json file to fix this issue.

And I have one more question need help.
I try to enable the SEL, I add below setting 
PACKAGECONFIG:append = " log-threshold log-pulse send-to-logger”

When event occurred, but SEL still empty.

event occurred log: 
Jan 01 00:04:25 fws7830bmc adcsensor[283]: Sensor MB_P3V3 high threshold 3.531 assert: value 3.588 raw data 1794
Jan 01 00:06:08 fws7830bmc adcsensor[283]: Sensor MB_P3V3 high threshold 3.531 assert: value 3.54 raw data 1770

Ipmitoo sel log:
SEL Information
Version          : 1.5 (v1.5, v2 compliant)
Entries          : 0
Free Space       : 65535 bytes or more
Percent Used     : unknown
Last Add Time    : Not Available
Last Del Time    : Not Available
Overflow         : false
Supported Cmds   : 'Reserve’ 

Please give me some advice. Thanks

Paul

I already fixed. I install module rsyslog and the SEL log will show when I run ipmitool.

Thanks for your help!
