lmFanSensorsValue
Module: LM-SENSORS-MIB
OID (symbolic): LM-SENSORS-MIB::lmFanSensorsValue
OID (numeric): 1.3.6.1.4.1.2021.13.16.3.1.3
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The rotation speed of the fan in RPM.
What is lmFanSensorsValue?
This read-only Gauge32 reports the fan's rotation speed in RPM. Admins poll this to detect a failing or stalled fan before it leads to overheating. For example, a healthy chassis fan might read around 3000 RPM, and a monitoring system would alert if this value drops to 0 while the system is powered on.
