What is this ?

The bubbleload monitor is a tiny, nice and multi-purpose system-monitoring application
connectable to any data-source in an easy way.
(it is just a quick hack built from the Libbubblemon gtk-example application)

The main purpose for writing this (expect the wonderfull bubbling water action)
was to be able to quickly "attach" it to any other data-source e.g. /proc-interface,
databases, network-services+daemons or any other log-files.

To archive this the bubbleload application is kept quite simple. It just
read 2 parameters (integer values) from a datafile (configureable by commandline args)
and displays the water-level and bubbling according those 2 values.
(take care, there is no error checking in the bubbleload source ;) feel free to add them)

The bubbleload binary is then "wrapped" into a script which updates the bubbleload datafile.
The wrapper-scripts is gathering and preparing the values from the datasource
of your choice into 2 integer values (fitting to the bubbleload-scaling), update
them in the bubbleload datafile sequentially and the bubbleload monitor displays
those 2 values as water-level and count-of-bubbles.
In this way the bubbleload monitor can be used for many other purposes
(without changing the sources and recompiling the binary)
by just writing a small new wrapper script "around it"

Included in bubbleload are 2 openMosix related wrapper scripts, one for
the head-node and one for compute-nodes in your openMosix cluster.
(bubbleload-om-head-node and bubbleload-om-compute-node)

.... as usual just another small idea which i would like to share with you

installation

- download + install Libbubblemon (http://www.nongnu.org/libbubblemon/)
- download bubbleload.tgz
- tar -xzvf bubbleload.tgz
- make
- run ./bubbleload-om-head-node

bubbleload-om-head-node
-> wrapper script for bubbleload
display load as water-level
and process-count as bubbles

bubbleload-om-compute-node
-> wrapper script for bubbleload
display load as water-level
and remote (guest) processes
as bubbles

.... more to come ;)
Those wrapper script just filling/updating the bubbleload-data file
(with some calculation to fit bubbleload scaling)
You can easily connect your own data-sources to the bubbleload monitor
by writting your own wrapper scripts to update the bubbleload-data file.

If you have a written a usefull wrapper script for the bubbleload monitor
feel free to send it to me and i will add it to download section
.... as one first idea a wrapper script usgin the gomd interface
would be great ;)
