Graphite is a highly scalable real-time graphing system. As a user, you write an application that collects numeric time-series data that you are interested in graphing, and send it to Graphite's processing backend, carbon, which stores the data in Graphite's specialized database. The data can then be visualized through graphite's web interfaces.
OpenTSDB is a distributed, scalable Time Series Database (TSDB) written on top of HBase. OpenTSDB was written to address a common need: store, index and serve metrics collected from computer systems (network gear, operating systems, applications) at a large scale, and make this data easily accessible and graphable.

smem is a tool that can give numerous reports on memory usage on Linux systems. Unlike existing tools, smem can report proportional set size (PSS), which is a more meaningful representation of the amount of memory used by libraries and applications in a virtual memory system.
A drop-in, low-overhead monitoring web dashboard for a linux machine.
Graphite is an enterprise-scale monitoring tool that runs well on cheap hardware. It was originally designed and written by Chris Davis at Orbitz in 2006 as side project that ultimately grew to be a foundational monitoring tool. In 2008, Orbitz allowed Graphite to be released under the open source Apache 2.0 license. Since then Chris has continued to work on Graphite and has deployed it at other companies including Sears, where it serves as a pillar of the e-commerce monitoring system. Today many large companies use it.

Simple PHP monitoring system, which aggregates and displays Pinba data.
Pinba is a MySQL storage engine that acts as a realtime monitoring/statistics server for PHP using MySQL as a read-only interface.
It accumulates and processes data sent over UDP by multiple PHP processes and displays statistics in a nice human-readable form of simple "reports", also providing read-only interface to the raw data in order to make possible generation of more sophisticated reports and stats.
A Process Control System. Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems.
It shares some of the same goals of programs like launchd, daemontools, and runit. Unlike some of these programs, it is not meant to be run as a substitute for init as “process id 1”. Instead it is meant to be used to control processes related to a project or a customer, and is meant to start like any other program at boot time.
Message Of The Day - System Status will dynamicaly generate the /etc/motd file with current information about system resources and usage. Using crontab the script will periodically display status of system resources and services. The original message of the day will be stored in the /etc/motd.orig file.
