hardwaremonitoring

Hardware monitoring refers to the ongoing observation of the health, performance, and utilization of computer hardware components. It tracks metrics such as temperature, voltage, fan speeds, power consumption, read/write error rates, and thermal throttling to detect anomalies and prevent failures. Effective monitoring supports reliability, capacity planning, energy efficiency, and informed maintenance decisions across servers, workstations, and embedded systems.

Monitoring relies on sensors present on components and on management interfaces provided by hardware and software layers. Common interfaces include IPMI and Redfish for remote management, SMBus/I2C and PMBus for sensor data, and S.M.A.R.T. for storage devices. Data are collected by agents or firmware on the host, transmitted to a central platform, and stored as time-series data. Alerts are generated when readings exceed thresholds or exhibit abnormal trends, enabling proactive intervention.

Typical tools range from low-level utilities such as lm_sensors or hwmon to full-featured monitoring stacks like Collectd, Telegraf, Prometheus, or commercial products such as Nagios, Zabbix, and PRTG. In data centers, baseboard management controllers (BMCs) and RESTful interfaces like Redfish enable out-of-band monitoring, while cloud and edge deployments may rely on agent-based telemetry and centralized dashboards. Standards and challenges exist around sensor availability and accuracy, security of management interfaces, and interoperability across vendors. Ongoing developments include AI-driven anomaly detection and expanded sensor support for GPUs, storage subsystems, and network devices.
