Hardware Sensor Attributes

For x64 servers, the management server software obtains the list of hardware sensor attributes to monitor through IPMI from the service processor of the server. For servers running the SPARC architecture, the ALOM interface is used. The list of hardware sensor attributes can vary from server to server, and between firmware versions. A sample listing for some servers and firmware versions is provided in this section. The attributes depend on the server type and on the number of CPUs that the server has.

To receive notifications for events from discrete sensors, create a notification rule and subscribe to the Ereport.Physical.ThresholdExceeded topic, as described in Setting Up Event Notifications.

For Sun Fire X4100 and Sun Fire X4200 servers, refer to the hardware documentation for to see the monitored hardware sensors.

For Sun Fire X2100 servers, only sensors describing fan speed, voltage, and temperature are used to retrieve data. Here is a list of sensors that are monitored for SP firmware version 4.11:

DDR 2.6V
CPU Core Voltage
VCC 3.3V
VCC 5V
VCC 12V
Battery Volt
CPU TEMP
SYS TEMP
CPU FAN
SYSTEM FAN3
SYSTEM FAN1
SYSTEM FAN2

For X2100 servers with SP firmware versions previous to version 4.11, CPU Core Voltage was called CPU Voltage.
