Note: thresholds capability is improving.Please report any errors and
requests (after reading the TODO file ;-).
### CHANGES ###
--- version 12.3 ---
all displayed cells with threshold now change color depending on
related threshold configuration (currently only in data tables, not
yet in viewers)
in threshold dialog box, added cell color selection column with
colored menu buttons, fixed and custom color selection
selected data cells are displayed with a sunken relief in all viewers
(except in graph and bar charts where selection is in white, due to
a bug in BLT)
empty threshold values are now allowed except for clock and numeric
when cell data is invalid, take no threshold action unless threshold
type is set to unknown
threshold condition is now immediately re-checked when threshold value
requires tktable 2.6 (2.5 fails when deleting rows in threshold dialog
new tktable 2.6 rpm and patch on my homepage (recommended but not
required), with the following fixes:
- text shifted down in active cell
- incomplete refresh on expose events
made check and radio buttons dark gray instead of reddish when
### README ###
This is moodss (Modular Object Oriented Dynamic SpreadSheet) version
Moodss won in the Best System Admin Technology category (Tcl Tips and
Tricks, Valuable Real World Programming Examples) at the O'Reilly
Tcl/Tk 1999 Conference.
Linux Magazine calls it a "lifesaver".
Tucows gives it 5 penguins (stars :-).
Moodss is a modular application. It displays data described and
updated in one or more modules, which can be specified in the command
line or dynamically loaded or unloaded while the application is
running. 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. Thresholds can be set on any number of cells.
Specific modules can easily be developed in the Tcl scripting language
or in C.
A thorough and intuitive drag'n'drop scheme is used for most viewer
editing tasks: creation, modification, type mutation, destruction,
... and thresholds creation. 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, thoroughly monitor a dynamic web server on a single
dashboard with graphs, using the Apache, MySQL, cpustats, memstats,
... modules. If you have replicated servers, dynamically add them to
your view, even load the snmp module on the fly and let your
imagination take over...
Along with a core trace module, random, ps, cpustats, memstats,
diskstats, mounts, route, arp, kernmods, netdev, pci, system, MySQL
(myquery, mystatus, myprocs, myvars) modules for Linux, ping, snmp and
snmptrap for UNIX, apache and apachex modules are included (running
"wish moodss ps cpustats memstats" mimics the "top" application with a
graphic edge and remote monitoring capability).
Thorough help is provided through menus, widget tips, a message area,
a module help window and a global help window with a complete HTML
Moodss is multi-langual thanks to Tcl internationalization
capabilities. So far only English and partially French are
supported. Help with other languages will be very warmly welcomed.
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 the tkTable, BLT, MIME/SMTP and the HTML
libraries 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):
Tcl/Tk 8.3.1 or above, at (or at a mirror near you)
http://dev.scriptics.com/ or ftp://ftp.scriptics.com/
the latest tkTable widget library at:
and the latest BLT library at:
(see the INSTALL file for complete instructions, for UNIX and also
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, blt and other rpms at:
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).
you may find it now at my homepage:
and a bit later at:
ftp://contrib.redhat.com/ in libc6 sub-directory.
Enjoy and please let me know what you think.
