Tests

The temperature sensors on the board are commonly connected through i2c busses. The configuration files specify the type of the device, the sensor name, the instance in that device, its location on the board, and the thresholds for reporting low, normal, and critical temperatures. To gather the information from the devices and report the values, the temptool uses the i2ctool.

The tool retrieves the data from the devices and validates that the temperatures are within the acceptable range.

CLI options

DellEmc Diag - Temperature Tool
version 1.4, x.xx.x.x-x
build, 2022/05/20,

Syntax: temptool <option>
  Show the help-text:=
       temptool --h                                           (or)
       temptool -h
  Test the pre-programmed configuration:=
       temptool --test --config=<config_file> [--lpc]         (or)
       temptool -t -f <config_file> [-l]
  Execute repeatedly command by count:=
       temptool --iteration=max/<count> [option1] [option2]...(or)
       temptool -I max/<count> [option1] [option2]...
  Show the current temperature-device values:=
       temptool --show --config=<config_file> [--lpc]         (or)
       temptool -x -f <config_file> [-l]

Usage:=
 -h, --h          Show the help text
 -t, --test       Test using the pre-programmed configuration or use supplied config
 -x, --show       Show operation
 -f, --config=    To specify the location of the config file e.g. /etc/dn/diag/<file_name>
 -I, --iteration= Iteration command execution
 -q, --lpc        Use LPC interface for reading temperature
                  LPC option MUST be used with show/test flags

• test—Tests the sensors to ensure they are within the acceptable range.
• show—Shows the current temperature values.
