ttyload home page

Hi there. ttyload is a little *NIX utility I wrote which is meant to give a color-coded graph of load averages over time. More information to come -- but by popular demand, I've gone ahead and "released" what I've got so far. Please respect my requests as outlined in the LICENSE file contained in the tarball. Screenshots^[0] are also available, if you want to see what it looks like.

Platforms:

In theory, this should work, or be relatively easily made to work, on most POSIX/UNIX type platforms. Platforms known to work include:

Linux
IRIX
Solaris
FreeBSD
MacOS X (Darwin)
Isilon OneFS

Porting for platforms that are derivatives of one of these should be trivially easy. Porting for other platforms should also be quite doable, though may require a bit more work. The program is structured to be (I hope) easy to port.

Getting the source:

Two choices:

Get it from GitHub -- git clone git://github.com/lindes/ttyload.git
Download one of the tarballs, below.

Download:

2013-03-12: ttyload-0.5.3.tar.bz2 is now available. Fixed the first github-tracked issue, about how time labels displayed along the bottom, especially with large -i values (e.g. -i 120).

2011-02-14: ttyload-0.5.2.tar.bz2 is now available. Minor (but old) bug fix -- now correctly displays the time at the top of the page!

2011-02-06: ttyload-0.5.1.tar.bz2 is now available. Minimal changes from 0.5, mostly just the fact that this project is now on GitHub!

2008-09-16: ttyload-0.5.tar.gz is now available for download. Several new options and behaviors added, most notably initial detection of window size. Also, new licensing, which should hopefully be OSS-compatible.

Previous version still available: ttyload version 0.4.4 (source code in tar.gz format)

MD5 (ttyload-0.5.3.tar.bz2) = e078fe59d94725ee41155e4d8de49087
MD5 (ttyload-0.5.2.tar.bz2) = 0eae93834914f307cb4295de7b9448b5
MD5 (ttyload-0.5.1.tar.bz2) = ad449fae217449d9df2acc2ec76b11c2
MD5 (ttyload-0.5.tar.gz) = b7f81a7f7c7069d76884e1f7c67e478b
MD5 (ttyload-0.4.4.tar.gz) = f331a7aa48f62cc1ff4d53d16b1fe032

See the change log for past changes.

Current features and limitations overview:

Runs on Linux, FreeBSD, IRIX^[1], and Solaris.
Uses fairly standard, but hard-coded, ANSI escape sequences for screen manipulation and colorization.
Ships with (but doesn't install, or even build by default) a relatively self-contained load bomb, in case you want to see how things work on an otherwise unloaded system.

Future plans:

more platforms
support for arbitrary sizing
dynamic resizing
Curses mode support (will probably be optional -- I want things to be able to run on old/quirky terminals, in theory)
a monochrome mode, just in case

Other possible future things:

make an X front end using the same basic engine, to have "3xload"
a "script"-happy, or otherwise logging-oriented mode

(At some point, I had the theory of changing the license on this so that it would become GratuityWare, but I'm not sure if/when this might happen, because I haven't written the GratuityWare Public License yet... and I'm not sure I ever will bother. ;-)

Footnotes:

[0] -- I also have a "screenshot" from a fan... that and perhaps future fanmail is being collected on the ttyload fan mail page.

[1] -- if 'uname -s' on your IRIX machine says "IRIX64", then in the ttyload directory, run this command before typing make: 'ln -s IRIX arch/IRIX64'. In a future release, I'll probably obviate the need to do this, but that works fine for the 0.4.3 release, and should continue to be the workaround until I get around to fixing it for real. :-)
