Yes - we definitely intend to implement better error reporting in perfsonarUI,
especially for services which support result codes. I've added such item on
our TODO list (E19):

http://wiki.perfsonar.net/jra1-wiki/index.php/PerfsonarUI#TO_DO

The Echos would be helpful for the fully automatic monitoring of the services
which we'll have to implement as well - many thanks for those updates!

Kind regards,
Vedrin

PS: The example you pointed below is very illustrative indeed ;-)
