How to prevent server hardware failures through monitoring tools?

To prevent server hardware failures through monitoring tools, you can implement proactive monitoring of critical hardware components such as CPU, memory, disk, power supply, and cooling systems. Monitoring tools help detect early signs of hardware degradation or anomalies, allowing you to take corrective actions before failures occur.

Key Monitoring Metrics:

1. CPU and Memory Usage: Track usage patterns to identify overloads or memory leaks.
2. Disk Health: Monitor SMART (Self-Monitoring, Analysis, and Reporting Technology) attributes like read/write errors, temperature, and bad sectors.
3. Power Supply: Ensure stable voltage and detect power fluctuations or failures.
4. Temperature and Cooling: Monitor server temperature and fan speeds to prevent overheating.
5. RAID Status: Check RAID array health to prevent data loss due to disk failures.

Example:

If a monitoring tool detects a sudden spike in disk read errors (SMART attribute Reallocated_Sector_Ct increasing), it may indicate an impending disk failure. You can proactively replace the disk to avoid downtime.

Recommended Solution:

For comprehensive hardware monitoring, Tencent Cloud's Cloud Monitor (CM) provides real-time insights into server hardware health, including CPU, memory, disk, and network metrics. It also supports custom alerts and automated responses to potential issues. Additionally, Tencent Cloud's CBS (Cloud Block Storage) includes built-in health checks for disk reliability.
