smartmontools contains utilities that control and monitor storage devices using the Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) system built into ATA and SCSI hard drives. This is used to check the reliability of the hard drive and to predict drive failures. Version 5.x is designed to comply with the ATA/ATAPI-5 specification. Future releases will comply with the ATA/ATAPI-6 and ATA/ATAPI-7 specifications. It is meant to be an up-to-date replacement for the ucsc-smartsuite and smartsuite packages, and is derived from that code.
memtester is a user-space utility for testing the memory subsystem in a computer to determine if it is faulty. It does a good job of finding intermittent faults and non-deterministic faults. It has many tests to help catch borderline memory. memtester should compile and run on any 32- or 64-bit Unix or Unix-like system.
phpSysInfo is a customizable PHP script that parses various files in /proc and displays them. It will display information about system facts like Uptime, CPU, Memory, SCSI, IDE, PCI, Ethernet, Floppy, and Video. It now has full internationalization support along with customizable templates.
HDT (Hardware Detection Tool) is an OS independent tool that displays low-level information on any x86 compatible system. It detects ACPI, CPU, PCI devices, DMI (memory, BIOS, motherboard, IPMI base board, chassis, batteries, CPU), disks (geometry, partitions), PXE environment, VESA modes, and VPD. It can also deduce the Linux kernel modules needed by a given host.
