hddtemp: Monitor Hard Drive Temperatures
A small utility to monitor and warn of hard drive temperatures, helping to prevent disk failures.
What is Hddtemp?
hddtemp is a lightweight, cross-platform software application that monitors the temperature of hard disk drives and solid state drives. It works by querying drive S.M.A.R.T. information to read temperature data.
Some key features of hddtemp include:
- Monitors disk drive temperature in real time and logs data over time
- Can warn users via email or other methods if temperatures exceed safe thresholds
- Lightweight with very few dependencies, runs on Linux, macOS, Windows, and more
- Open source software written in C, easy to build from source code
- Supports common interfaces like SATA, SAS, USB, and NVMe
- Output data in plain text, JSON, or other formats
By alerting users to excessive disk temperatures, hddtemp can help prevent failures from overheating conditions. It is commonly used by system administrators to keep track of hardware health stats across many servers. The data it provides can also assist troubleshooting performance issues.
