Hi Kaiwang,
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
Best regards
Thanh

a noop when the cache exists and is up to date. There is one sdr cache
per ipmi node, which defaults to
~/.freeipmi/sdr-cache/sdr-cache-<localhost>.<ipminode>
The logic resides in common code path defined in
common/toolsdr/tool-sdr-cache-common.c:sdr_cache_create_and_load(),
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
trunk(revision 8603).
