Now, let's have a look at what different colors indicates here: The memory bar gives you a broad perspective of how much of your system memory (RAM) and the swap memory are being utilized by the ongoing processes. Alpha Blue: Resources consumed by the virtualized processes.Red: Resources that are used by system (kernel) processes.Blue: It indicates low-priority threads.

Green: Resources utilized by user processes.Then, why use different colors in the same bar? Here's the breakdown for each one: And trust me, it explains a lot! CPU usage:ĬPU usage will show the total number of cores available in your system and will show the utilization of each one.

NetHogs can be built on Mac OS X and FreeBSD, but it will only show connections, not processes.

Since NetHogs heavily relies on /proc, most features are only available on Linux. This makes it easy to identify programs that have gone wild and are suddenly taking up your bandwidth. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. NetHogs does not rely on a special kernel module to be loaded. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs is probably what you're looking for:Ī small 'net top' tool. Edit: it only shows the streams, not the owner processes.
