The sys admin’s daily grind: QPS
The graphical tool QPS frees admins from Kafkaesque ambiguities about the cause, history, and side effects of running processes. Depending on the view, either clarity or detailed information dominate the scene.
Graphical tools are something I use sparingly – with the practical and fast QPS  being one exception. The process monitor, programmed in Qt combines the characteristics of top, PS, and lsof in a single package. The main window (Figure 1) shows central system parameters, such as CPU utilization, memory, swap, and uptime. This is followed by the tabular process list, which QPS presents in linear form, or as a tree.
