Adds support for showing columns with linux delay accounting. This information can be read from the netlink interface, and thus we set up a socket to read from that when initializing the LinuxProcessList (LinuxProcessList_initNetlinkSocket). After that, for each process we call LinuxProcessList_readDelayAcctData, which sends a message thru the socket after setting up a callback to get the answer from the Kernel. That callback sets the process total delay time attribute. We then set the delay percent as the percentage of time process cpu time since last scan.
htop

Introduction
This is htop
, an interactive process viewer.
It requires ncurses
. It is developed primarily on Linux,
but we also have code for running under FreeBSD and Mac OS X
(help and testing are wanted for these platforms!)
This software has evolved considerably over the years, and is reasonably complete, but there is always room for improvement.
Comparison between htop
and classic top
- In
htop
you can scroll the list vertically and horizontally to see all processes and full command lines. - In
top
you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident). htop
starts faster (top
seems to collect data for a while before displaying anything).- In
htop
you don't need to type the process number to kill a process, intop
you do. - In
htop
you don't need to type the process number or the priority value to renice a process, intop
you do. - In
htop
you can kill multiple processes at once. top
is older, hence, more tested.
Compilation instructions
This program is distributed as a standard autotools-based package. See the INSTALL file for detailed instructions.
When compiling from a release tarball, run:
./configure && make
For compiling sources downloaded from the Git repository, run:
./autogen.sh && ./configure && make
By default make install
will install into /usr/local
, for changing
the path use ./configure --prefix=/some/path
.
See the manual page (man htop
) or the on-line help ('F1' or 'h'
inside htop
) for a list of supported key commands.
If not all keys work check your curses configuration.
