Best Hardware Monitoring Software in 2026

Hardware monitoring software helps you keep track of sensor readings across the devices you oversee. Compare alert channels and custom sensor support to see how each option fits your monitoring setup; monitored device limits and sensor history add detail on scope and past readings. Remote monitoring and supported platforms can help you assess where you can view information, while free-plan availability and paid-from pricing offer cost points to compare. Netdata, Paessler PRTG Network Monitor, and Centreon are among the entries to consider, alongside Checkmk and Glances. Match the listed capabilities to the hardware you need to monitor and how you want to receive alerts or review sensor history.
