Troubleshooting Hardware Sensor Monitoring

Troubleshooting hardware sensor monitoring

This guide helps you troubleshoot issues related to hardware sensor monitoring across supported network devices. If temperature, voltage, fan, or power sensors are missing, show incorrect status, or fail to report values, this document walks you through the checks needed to isolate and fix the problem.
Use this guide to:
  • Validate vendor-specific Management Information Base (MIB) files and required object identifiers (OIDs) for hardware sensors.
  • Confirm that your devices expose correct sensor data over SNMP.
  • Understand vendor-specific differences in hardware sensor implementation.
