Qps - Visual Process Manager

(screenshot of qps in linear and tree mode)

Qps is a visual process manager, an X11 version of "top" or "ps" that displays processes in a window and lets you sort and manipulate them.

Qps can

change nice value of a process
alter the scheduling policy and soft realtime priority of a process
display the TCP/UDP sockets used by a process, and names of the connected hosts (Linux only)
display the memory mappings of the process (which files and shared libraries are loaded where)
display the open files of a process, and the state of unix domain sockets
kill or send any other signal to selected processes
display the load average as a graph, and use this as its icon when iconified
show (as graph or numbers) current CPU, memory and swap usage
sort the process table on any attribute (size, cpu usage, owner etc)
on SMP systems running Linux 2.1 or later (or Solaris), display cpu usage for each processor, and which CPU a process is running on
display the environment variables of any process
show the process table in tree form, showing the parent-child relationship
execute user-defined commands on selected processes
display MOSIX-specific fields and migrate processes to other nodes in a cluster

Qps runs on Linux and Solaris.

Download

Get the latest version (1.9.7), or read the README file. You can also browse the changes since previous versions.

Various people have kindly provided these packages, for easier installation:

format	platform	version	provider	comment
RPM	source	1.9.7	Tuan Hoang	Made with RPM v4.0.3
RPM	i386, RedHat 7.x	1.9.7	Tuan Hoang	Made with RPM v4.0.3
RPM	i386, RedHat 6.2	1.9.7	Tuan Hoang	Made with RPM v4.0.2
binary (.tar.Z)	Sparc Solaris 2.6+	1.9.7	Ross Campbell	statically linked, Qt not required
RPM	i586	1.9.5	Paolo Saggese
RPM	PPC	1.8.1	Jonathan Singer

The Linux binaries require glibc (libc6) and do not include MOSIX support (for this you have to compile from source).

The ancient version for Solaris 2.5 is here. It must be run as root. For Solaris 2.6 or later, the main sources should work, and no root privileges are required.
If you are using the window manager fvwm, then this patch (applies to fvwm 2.2) will remove the need for fvwm to destroy and re-create the qps icon when it changes (less flicker).

Requirements

Qt library 1.40 or later (get it here). Qt 2.x works.
Linux 2.0 or later, or Solaris 2.6 or later. (There is an old version for Solaris 2.5.x.)
A C++ compiler, if you compile from the sources.

Author

of this trivial utility is Mattias Engdegård (f91-men at nada dot kth dot se).

Mario Weilguni adapted (an older version of) qps to the KDE environment. It is called kpm and is available in some KDE distributions.
