## Symptoms

- */var/log/messages* file on Security Gateway running Gaia OS and SmartView Tracker logs from Security Gateway running Gaia OS repeatedly show the following messages about Hardware Sensors:

* Several times per second in */var/log/messages* file:

  ```
  
  xpand[PID]: Sending request to System Interface
  xpand[PID]: The max bit is 0 value is 0 max is 0.000000
  xpand[PID]: The min bit is 0 value 0 min is 0.000000
  ```

* Every minute:

  ```
  
  xpand[PID]:  Note: no Name_of_Sensor sensors
  ```

## Cause

1. On Security Gateway, these messages from the IPMI Testing utility about discovering the available IPMI Hardware Sensors appear in */var/log/messages* file because they are sent through SysLog with *usual* priority, whereas they should appear only with '*debug* ' priority.   

2. These messages from the IPMI Testing utility about discovering the available IPMI Hardware Sensors appear in SmartView Tracker because the corresponding box was checked in Gaia Portal of Security Gateway to send SysLog messages to the a Management Module (Gaia Portal - *System Management* pane - *System Logging*).
