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.

The Type 1 has a M, M(B), R, and R(B) value that is calculated from the values in the JSON.

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.
