ProcMeter3 is a program for monitoring the system status and other information and displaying it in a series of graphs or as text. Most of the information comes from the /proc filesystem (cpu usage, load average , processes information, memory usage, network traffic, interrupts etc.). Other information is available for other sources (date, time, email status, log file length, disk status etc.). The program is modular and highly configurable.
Sysload SP Analyst offers powerful means to control and analyze server performance. It provides real-time, continuous, fine-grained resource monitoring across Windows, Solaris, AIX, HP/UX, Linux, I-series, Citrix, Netware, and virtual machines (VMware Vi, IBM LPARs, Solaris X, I5 OS LPARs). It also provides incident and failure risk prediction and immediate analysis of the root cause of problems, allowing you to pinpoint the application(s) or user(s) responsible for server load increases.
SystemRescueCd is a Linux system available from a bootable CDROM that provides an easy way to perform administrative tasks on your computer, such as creating and editing the partitions of the hard disk or backing up data.

ICPLD (Internet Connection Performance Logging Daemon) is a connection monitor that sends ICMP requests to IP addresses of your choice and monitors if your machine has a working network connection. It logs failed attempts to reach the hosts, and will stamp a log as soon as a reply is received. It keeps track of when and for how long the connection was unavailable and records both total down time and each occasion of interrupted connection. It supports IPv6 and can execute a command whenever a connection goes up or down, which is useful for alerting users.
Log watcher is a PHP class that polls log files and takes newly added lines to send them to a given watcher email address. Although this class can be used to poll any type of log files, it was developed with the intention to overcome a limitation of the PHP error trapping system that is not able to capture certain types of errors during script execution, like script parsing errors or form file uploading failures. It is meant to be used from cron-like task schedulers to poll log files regularly. The email notification message can be composed from text templates. The message delivery function can be replaced by custom functions like the urgent mail function that can be faster for delivering critical messages.
