Thanks for your reply. I tested with/without recreating the cache before getting the sensor data. It works fine when the cache is recreated, e.g: CPU1 Temp 46 C nominal CPU2 Temp N/A unavailable
... Fan11 N/A unavailable Intrusion N/A unavailable PS Status N/A unavailable
but not when the cache is reused:
PS Status N/A unavailable PS Status N/A unavailable PS Status N/A unavailable
... PS Status N/A unavailable
The number of records in both cases are 30. The code is based on ipmi-sensors.c

I believe not. The cache is checked before real ipmi traffic, and it's
a noop when the cache exists and is up to date. There is one sdr cache
per ipmi node, which defaults to
The logic resides in common code path defined in
which is called by run_cmd_args(), which in turn called by
_ipmi_sensors(). You can find _ipmi_sensors as callback in main
function. All of them are in ipmi-sensors/ipmi-sensors.c, in the
