This is moodss (Modular Object Oriented Dynamic SpreadSheet) version
9.0. Moodss is implemented in the great Tcl language (requires at
least versions 8.2 of Tcl and Tk, for UNIX or Windows).
Moodss won in the Best System Admin Technology category (Tcl Tips and
Tricks, Valuable Real World Programming Examples) at the O'Reilly
Tcl/Tk Conference on August 24, 1999.
Moodss is a modular application. It displays data described and
updated in one or more modules loaded when the application is
started. Data is originally displayed in tables. Graphical views
(graph, bar, 3D pie charts, ...), summary tables (with current,
average, minimum and maximum values) and free text viewers can be
created from any number of table cells, originating from any of the
displayed viewers.
A thorough and intuitive drag'n'drop scheme is used for most viewer
editing tasks: creation, modification, type mutation, destruction,
... Table rows can be sorted in increasing or decreasing order by
clicking on column titles. The current configuration (modules, tables
and viewers geometry, ...) can be saved in a file at any time, and
later reused through a command line switch, thus achieving a dashboard
functionality.
The module code is the link between the moodss core and the data to be
displayed. All the specific code is kept in the module package. Since
module data access is entirely customizable (through C code, Tcl,
HTTP, ...) and since several modules can be loaded at once,
applications for moodss become limitless. For example, one can
compare a remote database server CPU load and a network load from a
probe on the same graph, or build a dashboard of CPU and memory
utilization for a group of servers.
Apart from a sample module with random data, ps, cpustats, memstats,
diskstats, mounts, route, arp modules for Linux, apache and apachex
modules are included (running "wish moodss ps cpustats memstats"
mimics the "top" application with a graphic edge). Module contibutions
are of course welcomed and will be included in my home page.
Thorough help is provided through menus, widget tips, a message area,
a module help window and a global help window with a complete HTML
documentation.
Development of moodss is continuing and as more features are added in
future versions, backward module code compatibility will be maintained.
I cannot thank the authors of tkTable, BLT, wcb and the HTML library
enough for their great work.
In order to run moodss, you need to install the following packages
(unless you can use the rpm utility, see below):
obviously Tcl/Tk 8.2 at (or at a mirror near you)
http://www.scriptics.com/ or ftp://ftp.scriptics.com/
the latest tkTable widget library at:
http://www.purl.org/net/hobbs/tcl/
and the latest BLT library at:
ftp://ftp.tcltk.com/pub/blt/
(see the INSTALL file for complete instructions, for UNIX and also
Windows platforms).
Note: pre-compiled libraries for tkTable and BLT on Linux are
available in my homepage.
You also have the option of using the moodss rpm file (also in my
homepage), if you are using a Redhat Linux system (6.0 or above).
You can find the required tcl, tk, tktable and blt rpms at:
http://www.multimania.com/jfontain/ or http://jfontain.free.fr/
Whether you like it (or hate it), please let me know. I would like to
hear about bugs and improvements you would like to see. I will correct
the bugs quickly, especially if you send me a test script (module code
with a data trace would be best).
