New meter displays same ARC stats as FreeBSD top(1). Can be extended to other platforms that support ZFS. Pulling kstat.zfs.misc.arcstats.c_max as the meter total, so the meter has a meaningful value to work up to. The Text meter displays, first, the maximum ARC size (Meter.total), then second, the total ARC used, using the difference between Meter.maxItems and Meter.curItems to "hide" the used value from the Bar and Graph drawing functions by using an index in Meter.values[] that is beyond curItems - 1, but less than maxItems - 1.
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
htopyou can scroll the list vertically and horizontally to see all processes and full command lines. - In
topyou are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident). htopstarts faster (topseems to collect data for a while before displaying anything).- In
htopyou don't need to type the process number to kill a process, intopyou do. - In
htopyou don't need to type the process number or the priority value to renice a process, intopyou do. - In
htopyou can kill multiple processes at once. topis 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.
