Jean-Luc Fontaine's Modular Object-Oriented Spreadsheet ... Well, this is what Jean-Luc has written: "I think this tool would be a good replacement for all those top-like graphical utilities in Linux distributions. Linux moodss modules already cover CPU, disk, memory, network devices statistics, ARP, kernel modules, PCI devices, mounted filesystems, processes, system data and routes, locally or remotely through ssh."

"Moodss -- Modular Administration" [L1 ] is a product review which UnixReview.com ran. "Moodss for monitoring" [L2 ], in NewsForge, gives more journalistic background on the application and Jean-Luc.

Description: The Modular Object Oriented Dynamic SpreadSheet (moodss)
package is implemented in Tcl/Tk 8 and displays tabular data
defined in independant modules. Complete help is provided.
Graphically can display graphs, side and stacked bar charts,
2 and 3d pie charts, summary tables,
and supports multiple element drag and drop.
Has multiple module concurrent support, help, summary tables.
Makes use of ghostscript to do print previewing.
Uses Tcl/Tk 8.3.1, tkTable 2.x, tkpiechart 5.2, BLT 2.4i.
Some modules are provided as examples which show graphical displaying
of apache/apachex, arp, cpustats, core trace, diskstats,
interrupts, kernmods, log, memstats, minimal,
moomps (Modular Object Oriented
MultiPurpose Service - a monitoring daemon), version 2.2 ,
mounts, various MySQL stats, minipy and randpy Python modules,
netdev, odbcquery, pci, ping, ps,
random, route, sensors, SNMP/snmptrap,
system modules for Linux. and trace modules, etc.
It can even keep track of all of this info on multiple servers.
Supports use of ssh for secure remote invocations.
Modules can be written in Tcl, Perl, Python, or C.
Complete HTML documentation is also included.
Tested with Unix and Windows 95.
A Redhat rpm with moodss, BLT, and TkTable is available.
Version 8.x corresponds to the Tcl/Tk 8.0 based releases.
Revisions to Version 8.x will cease to occur when Tcl/Tk 8.2
or newer becomes part of the main Linux distributions.
Version 9.x corresponds to Tcl/Tk 8.2.x.
Version 16.x corresponds to Tcl/Tk 8.3 and newer.

with "subscribe"Note that moodss is constantly moving forward: I have recently added the capability of storing history data with the associated moomps daemon in a SQL database.
We use that feature at work to monitor the traffic on 2 dozen WAN lines every day (1 sample per minute). A co-worker very quickly wrote a PHP page to display the data in a graph: it works like a charm (the MySQL database spits out a whole day data in 0.03 seconds!).
The whole setup took a couple of days, including Linux installation on a spare machine. That system is now used in production.
The next moodss release will allow browsing the database from the GUI, in a similar manner as real-time data is accessed.

Here is an update on how I use moodss/moomps, as of june 2003:
I use moodss at work to monitor 22 remote computing sites. Each site is connected to the main site, where the management Linux server (Red Hat 9) sits, by a WAN line, and each site contains a UNIX AIX server. Network trafic (in and out), CPU usage (system, user and input/output and usage for 5 specific families of applications), memory usage (total, swap input/output, and usage for each applications family) are periodically sampled (every minute or 5 minutes for the applications). All those data samples, collected 24 hours a day, 7 days a week, are stored in a MySQL database (4.0 series via mysqltcl). All the data is processed and stored by the moomps daemon, using SNMP (snmp module) and AIX specific modules. So far, tens of millions of samples have been stored, with the history database table being split in several tables (1 per month). Finally, data is made available to the users via dynamic web pages (in PHP with jpgraph) with daily graphs. The Linux server is a bi-processor (2 x 1.25 GHz Pentium III, 1 GBytes of memory), with a SCSI disk and a big IDE disk for daily backups).
Note: this is using Tcl/Tk 8.3.5, next step being moving to the 8.4 series.
Very nice article about moodds:

Another update on moodss in the real world:
Still monitoring 22 remote computing sites. Around 180 million data samples have been recorded by moomps so far. Moved to Tcl/Tk 8.4.6 and a bi-Xeon 2.4 GHz machine (which really gives 4 processors with hyper-threading enabled and Linux 2.4). Thresholds have been setup so that emails are sent to a bunch of people when WAN lines go down, on backup and up again. Next, 44 Windows 2003 servers will also be monitored, which should push the collected data rate to more than 20 million samples per month. Linux kernel 2.6 will be used to gain 10 to 20% performance on the MySQL database server.
