Sensor type.
●
Temperature: BMC monitors temperature of system components like CPU, PCH, DIMM,
PSU and HSBP, and monitors Inlet/Outlet temperatures.
●
Voltage: System P12V, P5V, P3V3, PVNN, PVDDQ, PVCCIO, PVCCIN.
●
Fan Speed: System fan.
●
Power Consumption: BMC monitors Total Power, CPU Power, Memory Power, PSU Input
Power. Fan Power and HDD Power are platform-specific.
●
System Main Component Health: BMC monitors system component’s health like, CPU
Status, PCH Status, MEM Hot, HDD Status, PSU Supply, ME FW Status.
●
Intrusion: Optional - An assertion event will be logged, when chassis cover is opened.
●
Button: An assertion event will be logged, when Power Button or Reset Button is pressed.
9.8.1.2 Virtual Sensor
BMC also reports various system state changes by maintaining virtual sensors that are not
specifically tied to physical hardware.
●
IPMI Watchdog: BMC supports an IPMI Watchdog sensor as a means to log SEL events due
to expirations of the IPMI 2.0 compliant Watchdog Timer.
●
Event Log: The Event Log sensor is used to indicate when the event log is cleared. An
assertion event is logged against this sensor when the SEL is cleared. This discrete sensor
also supports offsets that indicate when the SEL is full and almost full.
●
Clear CMOS: If BIOS CMOS is cleared by BMC, an assertion event will be logged.
●
System Restart: When system is cold reset, or hard reset, an assertion event will be logged
indicating system ever being cold reset or hard reset.
●
BMC Boot Up: When BMC boots up, an assertion event will be logged.
●
BIOS Boot: When BIOS boots up and host boots to OS, an assertion event will be logged.
9.8.1.3 Event-Only Sensor
Event-Only discrete sensors are used for event generation only and are not accessible
through IPMI sensor commands like the Get Sensor Reading (IPMI command). BIOS/OS or
other third-part client uses Add SEL Entry (IPMI command) to add event log to SEL.
