ANNOUNCE: moodss-19.5 and moomps-4.5
### CHANGES ###
--- moodss 19.5 and moomps 4.5 ---
- in formulas, added the following functions:
- last(): value of a data cell at last formula update time
- diff(): floating-point difference between data cell current
value and value at last formula update
- delta(): integer difference between data cell current value and
value at last formula update
- diff(time): time since last update (floating-point value in
(please test them and report any problem at
- all formulas are now only updated when refreshing occurs (every poll
time interval) instead of when any composing data cell value changes,
in order to avoid useless updates and improve performance (note: also
check formulas do***entation for the special case of data coming from
- updated myvars module for MySQL 4.1.8 support
- added support for mysqltcl MySQL interface library version 3
- in diskstats modules, fixed remote monitoring (via rsh or ssh, bug
introduced in 19.4 moodss release)
### README ###
This is moodss (Modular Object Oriented Dynamic SpreadSheet) version
19.5 and moomps (Modular Object Oriented Multi-Purpose Service)
For Unix Review, moodss is "a must-have application for today's
network and systems administrators", and for Eric S. Raymond, in "The
Art of UNIX Programming" book: "the code is polished, mature, and
considered an exemplar in the Tcl community."
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), tables of mathematical formulas
and free text viewers can be created from any number of table cells,
originating from any of the displayed tables or 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.
For both moodss and moomps, it is also possible to use a database as a
storage mean, so that data history is recorder and later made
available, for example, in 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.
Many modules are provided, such as a comprehensive set for Linux
system monitoring, MySQL, network, SNMP, Python and Perl modules
examples. 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...
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. English, Japanese and 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.
