Hi everybody: here is a new version of moodss.

Check it out! (or at least the screenshots at http://jfontain.free.fr/moodss3.gif or http://jfontain.free.fr/moodss4.gif :).

Note: thresholds capability was added. It is still in embryonic state but does work. Please report any errors and requests (after reading the TODO file ;-).

### CHANGES ###

--- version 12.0 ---

- in MySQL mystatus module, values in kilobytes went negative when value retrieved from server (in bytes) passed 2**31 - MySQL mystatus and myvars modules now compatible with 3.23.28 server

- first pass at thresholds setting capability (see HTML documentation for more information) - added threshold drop icon in main window - added threshold entry in edit menu - on all displayed data tables, column sizing is now automatic and manual sizing is disabled (a module code specific flag will be added in next release to enable manual sizing) - in summary data tables, average column values were wrongly calculated for dynamically created rows - in free text viewer, restoring from save file did not work if data cells were inserted in random order - improved icons look and placement - set widgets border widths to 1 to improve looks and reduce windows size - uses scwoop 4.0 - preferences dialog box had configuration in title instead of preferences - with no module loaded, creating an empty graph viewer would cause an error - in system module, added number of users and processes rows - in diskstats module, added support for 2.4 Linux kernel series - clicking on column title sorting arrow now also toggles sort - new slicker grayish drag and drop icons - successfully tested with Tcl/Tk 8.4a2 - uses some new features of Tcl/Tk 8.4 in code whenever possible

### README ###

This is moodss (Modular Object Oriented Dynamic SpreadSheet) version 12.0. Moodss is implemented in the great Tcl language (requires at least versions 8.3.1 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, Linux Magazine calls it a "lifesaver", and is worth about 5 penguins at Tucows.

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.

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). 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.

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 tkTable, BLT 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 8.3 at (or at a mirror near you) http://www.scriptics.com/ or ftp://ftp.scriptics.com/ the latest tkTable widget library at: http://www.hobbs.wservice.com/tcl/main.html and the latest BLT library at: ftp://tcltk.sourceforge.net/pub/tcltk/blt/ (see the INSTALL file for complete instructions, for UNIX and also Windows platforms).

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: 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).
