lmVoltSensorsValue
Module: LM-SENSORS-MIB
OID (symbolic): LM-SENSORS-MIB::lmVoltSensorsValue
OID (numeric): 1.3.6.1.4.1.2021.13.16.4.1.3
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The voltage in mV.
What is lmVoltSensorsValue?
This read-only Gauge32 reports the voltage reading in millivolts (mV). Admins poll this to detect a power supply rail drifting out of spec, which can cause instability. For example, a value of 3300 represents 3.3V, and a monitoring system might alert if a nominal 12V rail (12000 mV) drops below 11400 mV.
Examples
