EtherApe is an open source application (works on Linux, Mac, BSD, Solaris) for monitoring your network data traffic. EtherApe offers a dynamic graphical interface; features IP and TCP modes; supports Ethernet, FDDI, PPP, and slip devices; filters traffic; and reads traffic from both a tcpdump file and live from the network.

Each node represents a specific host. Links represent connections to hosts. Nodes and links are color coded to represent different protocols forming the various types of traffic on the network. Individual nodes and their connecting links grow and shrink in size with increases and decreases in network traffic.

You can also view the traffic for each protocol as a list:

Yet Another (remote) Process Monitor (YAPM) is a powerful Windows application that allows to view and manage your running tasks, processes, threads, modules, windows, handles, network connections and your services on a local or on a remote machine. YAPM offers lots of features to manipulate them, such as privilege management, memory management, a complete history of statistics, a dependency viewer... etc. Service startup types can be managed, processor affinities specified, and there's a grayed-out option for limiting CPU usage that will likely be active in a future version.

Don't recognize a specific process (say, for example igfxpers.exe)? Highlight it and click the internet search button to be taken directly to Google's results for clarification. You can also put YAPM's Kung Fu to use monitoring remote machines on your network.

In all honesty, there's so much built in to YAPM that you really need to download it and give it a try - assuming you want a better system monitor.

Features:

* Local and remote monitoring
* Module and thread management
* Handle management (keys, files...)
* View of TCP/UDP connections opened by the processes
* Windows management (opacity, position, show, hide...)
* Window' find' process feature : allows to find the process associated to a window via a drag & drop over the screen
* Emergency Hotkeys feature : allows to associate a custom shortcut to a custom action (for example : Ctrl+Shift+Suppr to close the window which is on foreground)
* State Based Actions feature : allows to launch a custom action depending of the state of the processes (for example : reduce priority of a process if CPU usage > 50%)
* Privilege management : allows to view and modify the privileges of processes
* Build-in hex editor to view memory of processes
* "Log mode" to monitor all actions made by a specific process
* Hidden Processes feature to detect basic rootkits
* Local and remote shutdown
* Dependency viewer
* ... And lots & lots of other features !

Requirements

• .NET Framework 2.0 .
• Administrator rights, if you want to access to system processes and some other informations. For now, it is really better to have administrator rights, but in the future, more informations and actions will be available even if you do not have these rights.
• For remote monitoring, WMI (Windows Management Instrumentation) must be installed and available on both machines if you use WMI method, or the YAPM Server application must be started on the remote machine if you use the client-server method.

Yet Another Process Monitor is almost portable (it requires .NET Framework 2.0 as you have seen above), freeware, open-source and works on Microsoft Windows XP, Windows Vista or Windows Seven (32 bits only).

watsup is a simple application for Ubuntu that monitors system resources and the processes using those resources and you can also use it to kill a process.

It is different from monitor programs you have seen before:

* Overhead is low, supporting a sample interval down to 0.1 seconds
* Overall system and top process resources are shown on one page
* CPU, memory, disk I/O, network I/O, and page faults are monitored
* Font can be made small (for display in a corner of the monitor) or large
* The N top-ranked processes fitting in the window are shown with minimal jumping around between samples (easier to watch one or a few processes)
* Process rank is a weighted sum of CPU, hard page faults, and disk I/O over the last several samples (sample weight declines over time)
* A process can be selected with the mouse and killed
* Optionally display processes matching given users, PIDs, or exe file names

Download the watsup .deb file from here.

After installing it, hit Alt + F2 on your keyboard and type: watsup
