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