10.1CMM Sensor Types

The CMM provides access to and can log events from different IPMI sensor types. These sensors can be both threshold-based sensors or discrete sensors, depending on the type of reading and events they generate. For more information on sensors and sensor types, refer to the “Intelligent Platform Management Interface Specification v1.5”, available on http://www.intel.com.

10.2Threshold-Based Sensors

Threshold-based sensors are sensors that generate or change an event status based on comparing a current value to a threshold value for a given hardware monitor device. Examples of threshold- based sensors are temperature, voltage, and fan tachometer sensors.

10.2.1Threshold-Based Sensor Events

Threshold-based sensors generate events when a current value for a device becomes greater than or less than a given threshold value. The IPMI specification defines six thresholds that can be assigned to a given sensor. The sensor will generate an event when its current reading goes above or below any of these thresholds. The severity of the event generated depends on which threshold is crossed. These six thresholds and their associated event severity are as follows:
