Issue/Introduction

Messaging Gateway (SMG) sends a Hardware Failure alert for a CPU temperature condition but reviewing the logs shows that a high temperature condition has not been recorded. Instead, the recorded temperature is displayed as "Unknown" in the messages log.

2021 Apr 22 11:15:20 (crit) SMS: [-]  CPU internal temperature in Failure state (Unknown C)

Cause

The tool used to detect the planar CPU temperature is returning an unexpected or empty value rather than the CPU temperature.

 

Environment

SMG 8340 / Dell R210-II hardware
SMG 8340 / Dell R230 hardware

Resolution

This issue was addressed for the Dell R210-II hardware model with the Messaging Gateway 10.6.2 release but has reoccured on the Dell R230 hardware model.

The false positive alerts are currently under investigation by the SMG product engineering team.
