Description: IBM MIB for hardware sensor monitoring providing temperature, voltage, and fan speed readings on IBM server hardware.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is IBM-SYSTEM-LMSENSOR-MIB?

This is an IBM-proprietary MIB (part of the IBM System family of low-level hardware sensor MIBs) used to expose readings from onboard hardware monitoring sensors on IBM server platforms, similar in spirit to Linux lm-sensors. It centers on a temperature sensor table reporting current, nominal, minimum/maximum readable, and tolerance values per sensor. It is squarely a hardware-status monitoring MIB: its purpose is to let management software detect when a server's internal temperature drifts outside its normal operating envelope, often the earliest warning of a cooling failure or overloaded component. It has no apparent dependency beyond IBM's own enterprise MIB tree and is not built on a standard IETF hardware MIB. It is typically polled by IBM systems-management agents or third-party NMS platforms on IBM Power/System x rack and blade servers to feed temperature trending and threshold alerting. Engineers can download the IBM-SYSTEM-LMSENSOR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in IBM-SYSTEM-LMSENSOR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

IBM System x / Power series rack or blade server

Monitoring Examples

A monitoring system walks ibmSystemTemperatureSensorTable, keyed by ibmSystemTemperatureSensorKeyIndex, comparing ibmSystemTemperatureSensorCurrentReading against ibmSystemTemperatureSensorNormalMax/ibmSystemTemperatureSensorNormalMin for each entry. If ibmSystemTemperatureSensorCurrentReading exceeds ibmSystemTemperatureSensorNormalMax by more than ibmSystemTemperatureSensorTolerance, or approaches ibmSystemTemperatureSensorMaxReadable, that signals a cooling problem such as blocked airflow or a fan failure inside the chassis. Comparing against ibmSystemTemperatureSensorNominalReading over time helps establish a baseline for detecting slow thermal degradation.

What Can Be Monitored

current temperature sensor reading
nominal/normal temperature range
min/max readable temperature bounds
