PRTG Catches Network Issues Before They Cause Downtime
Threshold-based alerts flag problems early, so your team can act before users notice, not after.
Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
sarface is a user-interface to the sysstat/sar database which inputs data from sar and plots to a live X11 graph via gnuplot. It mimics the cmd-line options from sar but can cross-plot any two or more stats and apply simple mathematical functions them.
Sysglance profiles the linux computer, providing the user withan at-a-glance snapshot of the computer. The program is Python based and currently relies on the dmidecode utility to collect the majority of it's information.
This program has been forked and Autokernel has been abandoned. Please check out KernelCheck: http://kcheck.sourceforge.net/ Autokernel, a program that automatically recompiles and optimizes the kernel to your needs.
Graphical or terminal-based stopwatch with many user-named lap timers. Save / restore timing results via CSV file; timer "runs" even when application isn't running! Supports lap timer label templates. Hildonized (i.e., also runs on Maemo / Nokia 770).
Rugg is a hard drive and filesystem harness tool that allows you to test and benchmark drives and filesystems, by writing simple to complex scenarios that can mimic the behaviour of real-world applications.
GL O.B.S. is based around a PyGTK interface that launches OpenGL programs feeding them with a common CLI options set which will affect their behaviour, then receives back their statistical output. Benchmarks are easy to create and add.
Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization data and process information are collected during the boot process and can later be displayed in a PNG, SVG or EPS chart.

ClusterScores is a cluster benchmarking tool which automate compile, benchmark, and report benchmarking on cluster. This tool integrates other standard cluster benchmark tools such as HPL, Stream, Netpipe, Iperf, Bonnie, IOZone, etc...
Free Java monitoring library to easily instrument apps to measure performance detail over time with minimal overhead. Has dashboard, SVG graphs. Extends Jamon and its statistical data, same usage. http://www.e-peas.com/opensla/. JMX, SNMP planned.
"QoS_Man" is a project for simulating QoS manager in Dynamic Real-Time Systems(DRTS).The QoS manager is just part of proposed architechtural model for resource management in DRTS.For more information, visit "results n papers" dir in cvs repository.
"Traffic" is ethernet/ip traffic generator. The tool consists of server and GUI application.
Typical configuration is to have at least 2 servers and 1 or more client machines, where the servers are controlled and results are displayed.
This project is an approach to automating the testing of performance properties of complex systems.Just like functional specs for software we aim to develop an executable language for asserting performance expectations of a program.This implements Sharon
PyWebPerf is a performance measuring tool written in Python which simulates a web browser fetching a page (handles cookies, multiple threads, image and css download). Command-line and cgi interfaces are provided, with a scripting facility coming soon. Do
The PagingMon (Paging Monitor) project aims to provide a *real time* visualization of page-in and page-out activities in a virtual memory system. The name comes from PokeMon, which is a popular Japanese cartoon.
OpenLC is a set tools designed to facilitate benchmarking and stress
testing of a wide variety of information servers (WEB, Email, FTP,
LDAP, ...). A XML-RPC API is offered for developers interested in
creating clients that query the services provid
A benchmarking utility providing administration of the benchmarking procedure and a web interface for public access on the results. The goal is to have an automated procedure after the benchmark specification.
