How to Monitor CPU Temperatures and Power Consumption in Real-Time

Real-time monitoring of CPU temperatures and power consumption helps prevent overheating and ensures energy efficiency in HPC environments. Follow this guide:

Step 1: Install Monitoring Tools

• Install Linux-based monitoring tools:
• sudo yum install lm_sensors ipmitool

Step 2: Configure Sensors

• Detect available sensors and follow configuration prompts:
• sudo sensors-detect

Step 3: Monitor CPU Temperatures

• Check real-time CPU temperatures using:
• sensors

or

watch -n 1 sensors

Step 4: Monitor Power Consumption

• Use IPMI tools to monitor CPU power consumption:
• ipmitool sensor | grep -i 'power'
• For systems supporting Intel RAPL (Running Average Power Limit):
• turbostat

Step 5: Continuous Real-Time Monitoring

• For continuous monitoring, automate scripts or use monitoring tools like Prometheus/Grafana.

Step 6: Alerts and Notifications

• Configure monitoring software to send alerts if temperatures or power usage exceed predefined thresholds.

Step 7: Analyze and Document

• Regularly review temperature and power consumption data.
• Document monitoring methods, findings, and optimization measures.

Real-time monitoring ensures proactive management of CPU health and energy usage, enhancing HPC system reliability and performance.
