dgx-spark-temperature#

Read hardware temperature sensors on the DGX Spark via SNMP.

When to use#

• User asks for body temperature, DGX Spark temp, hardware temps, how hot things are running
• Any temperature/hardware health check request for the DGX Spark

How to use#

Run exec with:

text

bash <workspace>/skills/dgx-spark-temperature/check_temperature.sh

The script uses:

• snmpwalk -v2c -c licpub dgx-spark1.fiber.house 1.3.6.1.4.1.2021.13.16.2.1
• Parses LM-SENSORS MIB table: lmTempSensorsIndex, lmTempSensorsDevice, lmTempSensorsValue
• Values are in milliCelsius — divide by 1000 for °C
