 +  * modinfo - describe module and arguments that can be provided
 +  * htop - top on steroids
 +  * atop - lists the most active processes based on CPU, memory, disk and network usage
 +  * iotop - lists io usage of programs.
 +  * duc - visualise disk usage
 +
 +===== Networking =====

 +  * iftop - lists network usage by ip address
 +  * iptraf - similar to iftop but has a bit more functionality
 +  * nethogs - per process network usage
 +  * nload - per interface usage and console graph
 +  * ntop - not what you're looking for
