DigiTemp uses a simple serial port adapter to read temperatures from the Dallas Semiconductor 1-Wire DS1820 digital temperature sensors. It supports the DS9097-U adapter, supports DS2409 based 1-Wire hubs, and features a 1-Wire walk that will display all devices on the LAN, not just temperature sensors.
System Health Monitor is a program that handles the work of setting up monitoring of network interfaces, memory, load, drive space, and running processes. It generates graphs and HTML files when called via cron every 5 minutes. It requires Round Robin Database to store the information and generate the graphs.
