Description: Lenovo MIB for monitoring environmental sensors including temperature, fan, and voltage on Lenovo 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 LENOVO-ENV-MIB?

LENOVO-ENV-MIB is a Lenovo vendor-specific SNMP module for monitoring environmental conditions on Lenovo server hardware, covering power supplies, fans, and temperature sensors, and it also defines related environmental notifications/traps. It exposes power supply and fan tables with per-unit identity, description, name, and operational state, along with temperature sensor threshold objects. This MIB is fundamentally about monitoring hardware status: it directly reports power supply health state, fan health/identity, and temperature threshold conditions, the core signals administrators use to catch overheating, a failed fan, or a lost power supply before it causes an outage. Its notification prefix object indicates it defines SNMP traps (built on standard SNMPv2 NOTIFICATION-TYPE conventions) to proactively alert on these environmental events rather than requiring only polling. It is typically deployed in Lenovo ThinkServer/System x rack and tower server environments as part of a broader server hardware health monitoring solution alongside the vendor's XCC/IMM management controller. Engineers can download the LENOVO-ENV-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LENOVO-ENV-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

Lenovo ThinkServer/System x rack or tower server

Monitoring Examples

An administrator polls lenovoEnvMibPowerSupplyTable/lenovoEnvMibPowerSupplyEntry (indexed by lenovoEnvMibPowerSupplyIndex) to check lenovoEnvMibPowerSupplyState for each lenovoEnvMibPowerSupplyID/Desc, catching a power supply that has transitioned to a failed or missing state in a redundant PSU server. Similarly, lenovoEnvMibFanTable/lenovoEnvMibFanEntry reports lenovoEnvMibFanID and fan health, revealing a stalled or removed fan module. lenovoEnvMibTempSensorThresholds would be checked when a temperature-related trap fires (via lenovoEnvMibNotificationPrefix) to see which threshold was crossed. Together these let an admin correlate a trap event with the specific failed component.

What Can Be Monitored

power supply operational state per unit
fan health/identity per unit
temperature sensor threshold status
environmental fault notifications/traps

How to Use in IPNetwork Monitor

Example using lenovoEnvMibFanSpeedPercent OID:

Select a Lenovo ThinkServer/System x rack or tower server (environmental sensors) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type lenovoEnvMibFanSpeedPercent into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the speed of the fan as a percentage. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the speed drops below the level expected for a healthy, spinning fan, since a stalled or slowing fan often precedes overheating. Click Finish to create the monitor; you can adjust any parameter later.
