There is a contrib archive on our server, but there are not too many
scripts... I would like to anything you may want to share :-)

You could hack the monitor script or you could hack the netguard code
(which needs some hacking to get it going).

In the long term, I would like to use the SNMP agent code of scotty
and the MLM MIB to do (offline) monitoring tasks. The idea is to break
all the monitoring jobs into very basic tasks that subscribe requests
for network information which is retrieved by a scheduler. This
scheduler will be able to do optimizations to reduce the number of
requests (which is not possible with the netguard solution). The
results will be stored in the MLM result table so that any SNMP
manager can make use of the information (not only tkined and scotty).

There is another related thing that I want to change: Currently, the
monitoring scripts create a stripchart or a barchart tkined
object. Monitored values are written to this object. I would like to
replace the stripchart and barchart objects with something more
general, lets call it a data stream object. This allows to change data
representation while a monitoring job is running and it. It would be
very easy to write the data stream into a file to get long term
statistics (if you can run tkined 24 hours a day).

Note, that I have no idea when these things will happen.

You can stretch or shrink networks that are a simple line (not
polylines). Just select the Alter tool, click near one end and drag
the mouse while pressing the left mouse button. This is not very
obvious and no real solution, but it works...
