Dgx Spark Temperature

Reads and reports hardware temperature sensor values from the DGX Spark system via SNMP for hardware health monitoring.

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

Sensor mapping (16 sensors)
