Apache JMeter a 100% pure Java desktop application designed to load test functional behavior and measure performance ascpu an X windows applet with AfterStep look which displays the current CPU load (user/system/nice) and calculates the average load asmem a X11 application with AfterStep look and feel that acts as a memory utilization monitor asmon asmon is a swallowable applet monitors the CPU usage, memory usage, swapping etc. atop The command atop is an ASCII full-screen performance-monitor on system-level and process-level. It looks similar to the other full-screen monitors, however there are some major differences. It shows the resource-consumption of all processes which were active during the interval, so including those processes which finished during the interval. It also shows system-level counters concerning cpu-, memory- and swap-utilization, but also disk I/O and network utilization counters are shown on system-level. bubblefishymon a dockapp-style CPU, memory, swap, load average, and network monitor Bubbling Load Monitor Applet a system CPU and memory load monitor for the GNOME panel. It displays something that looks like a vial containing water Conky Conky is an advanced, highly configurable system monitor for X. CPU Fire Load Monitor CPU Fire Load Monitor is a GNOME panel applet showing CPU load as a fire. The higher the flames go, the higher the CPU load. deskbar Deskbar is a lightweight system monitor without large dependancies to other libraries or toolkits. It's completely build on top of the Xlib. The output will be written directly to the root window, so the placing and all other configuration is done via a XML based configuration file. Eddie a system monitoring tool developed entirely in Python. Its key features are portability, powerful configuration and ease of expansion ESM ESM (Extensible System Monitor) is a program that lets you tie together plugins to monitor your system.

Fire Applet Fire Applet is a panel applet for KDE 3 that shows an animated flame. The higher the CPU load, the bigger the flame gets. Alternatively, the flame can be set to a fixed intensity. gisdnload an ISDN load meter for Linux running as a Gnome applet. It displays like xisdnload the load of your ISDN lines. The display supports autoranging and changes its background color depending on whether you are online or offline GKrellM GKrellM is a stack of monitors which can be integrated visually with a window manager or GTK theme. GKrellM charts CPU, Disk, load and all active net interfaces automatically. An on/off button and online timer for the PPP interface is provided. It includes meters for memory and swap usage as well as a system uptime monitor. GKrellm SNMP Monitor a single process with many readers stacked onto your display Gmemusage Gmemusage is a graphical memory usage viewer. gnetload a network and ISDN load meter that is similar to xisdnload, but works in a distributed environment. It includes an agent (devstata) that runs on machines with interfaces to be monitored and periodically sends status information over the network gpdial_applet gpdial_applet is a GNOME panel applet that can monitor a file and rip an integer or floating point number out of a row/column in that file and display it in a dial or gauge meter. gr_monitor gr_monitor displays information about processes resident on a UNIX system. gsysinfo a system monitor for the gnome panel, modelled after the heatload a tool for Linux which plots the CPU load against the CPU temperature as measured by the ACPI subsystem hsysmon gKrellm simply wastes too much space on a small (e.g. Notebook) screen, so this presents all needed information in a small horizontal window Iotop Iotop is a program with a top-like UI that shows which processes are performing the most I/O on a Linux system. ips an intelligent process status program iTop a top-like interrupt load monitor k3 k3 displays the memory available as a percentage, the K free, and a simple bar chart. Karamba a KDE program to display information on your desktop using various sensors and display types. It also is able to execute python scripts for interaction, among other things klavg a small KDE applet showing load average graph on the panel kperfmeter kperfmeter is a simple performance statistics monitor in the style of the well known perfmeter. LCDproc LCDproc is a small program that displays system statistics on a 20x4 LCD (made by Matrix Orbital). Link Monitor Applet a GNOME Panel Applet displaying the round-trip time to one or more hosts in a bar graph, featuring: full ICMP and ICMPv6 support, configurable scale and delays and HIG 2.0 compliance Linux Monitor monitors processes, disk space and load avarage Loadmeter Loadmeter is a Linux system resource monitor that uses very little memory, and is written in raw Xlib. Loadmon.Epplet a simple load monitor for Enlightenment lsnet lsnet is a system monitor that generates detailed charts for viewing on your Web site. One pixel represents 1 minute. It displays data for one day. MasarLabs NoArp filters and drops unwanted ARP requests. It is useful when you are using Linux kernel 2.4.19 and need to add an alias to the loopback interface to use a load balancer Micro-Partitioning statistics tool This is a Micro-Partitioning statistics and documentation tool for IBM System p and System i servers running AIX/Linux/AS400. The tool is able to produce historical CPU utilization graphs of LPARs and shared CPU usage, and collects physical and logical configuration data. Monitorix Monitorix is a free, open source system monitoring tool designed to monitorize as many services as it can. At this time it monitors from the CPU load and temperatures to the users using the system. Network devices activity and network services demand are too monitorized. The current status of any corporate Linux server with Monitorix installed on can be accessed via a web browser. mpstat mpstat helps in the monitoring of SMP machines CPU %usr, %idl, maj&min faults, interrupts, i.e. per processor statistics. mpstat is similar to vmstat. MSysM MasarLabs System Monitor: a lightweight X11 application that displays constantly updated graphs and data informations of your system mytop mytop is a non-gui tool for monitoring the threads and overall performance of MySQL servers. Read more Nagios Console Monitor nsc is a curses-based tty/console monitor for Nagios v1/v2. It allows you to monitor Nagios services without the expense or availability of a GUI. nload nload is a console application which monitors network traffic and bandwidth usage in real time. It visualizes the in- and outgoing traffic using two graphs and provides additional info like total amount of transfered data and min/max network usage. NodeMon NodeMon is a resource utilization monitor tailored to the Altix architecture, but is applicable to any Linux system or cluster. It allows distributed resource monitoring via the Growler software infrastructure. It is modular, with existing modules for monitoring of CPU, memory, network, and numalink activity. Its most notable feature is its composition of large amounts of statistics into a single graphical window. It was originally designed for monitoring NASA's Columbia supercomputer. osdcpufreq osdcpufreq displays an OSD-like window (similar effect as a television's on-screen volume control) with information about the CPU current status, including frequency, driver, and governor. Particle Spraying CPU meter Particle Spraying CPU meter is an applet for KDE Kicker that displays the CPU activity by spraying animated particles into the small applet window. Procman Procman is a GNOME process viewer and system monitor. It is hoped to be a replacement to gtop with a much nicer and simpler interface. ps3 ps3 is a utility for monitoring process activity on a Linux machine. It is a bit like top, but with three main differences: displays all processes, updates itself up to 100 times per second instead of once every three seconds & shows a 3D chart, with interactive rotation, zooming and scaling. pscpug pscpug is a unix utility designed to graph a given process's CPU usage over time. Since you can see changes over time, it is often more useful than top for checking on a specific errant process.
