- added Oracle database support
- in moodss GUI:
- use BWidget tree instead of BLT tree implementation
- use arrow mouse cursor in all help windows
- no longer exit on database connection failures when starting
recording history or loading from database

or pie charts by a direct data cell drop into their iconic drop
- trying to store data cell history from a module without options no
longer generates an error
- added optional debugging code (commented out) in database layer
- in snmp and smithy modules, use full OID in dotted notation for
sysUpTime in order to avoid MIB lookup
- successfully tested with mysqltcl version 2.20

### README ###
This is moodss (Modular Object Oriented Dynamic SpreadSheet) version
17.4 and moomps (Modular Object Oriented Multi-Purpose Service)
For Unix Review, moodss is "a must-have application for today's
network and systems administrators".
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 stars (cows or penguins :-).
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 viewers
(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. The display area can be extended by adding pages
with notebook tabs. Thresholds can be set on any number of cells.
Moomps (shipped with moodss) is a monitoring daemon which works using
configuration files created by moodss. Thresholds, when crossed,
create messages in the system log, and eventually trigger the sending
of email alert messages and the execution of user defined scripts. It
is also possible to use a database as a storage mean, so that data
history is for example available for presentations and graphs, via
commonly available spreadsheet software.
Specific modules can easily be developed in the Tcl, Perl and Python
scripting languages 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 loaded at the user's convenience,
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,
Perl, Python, 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, ODBC, 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, arp, cpustats, disks, interrupts,
kernmods, log, memstats, minimal, mounts, netdev, partitions, pci, ps,
random, route, sensors, system modules for Linux, MySQL (myerrorlog,
myhealth, myprocs, myquery, myreplication, mystatus, myvars),
odbcquery, ping, snmp, snmptrap for UNIX, apache and apachex, Minimal
and Random Perl modules, minipy and randpy Python 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-lingual 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.
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).
