perfSONAR User Q&A and Other Discussion

[Jason Zurawski <>]

Hi Szymon;

There are two things to note:

1) The identical src/dst is a 'self' test, and is different from the test you 
configured to some external host.  This self test is always configured when 
you enable owamp, the goal being to give you an indication of how the tool 
performs on the host (e,g. if the results were not stable, the host could be 
very busy, out of memory, or in some form of distress).  

2) The test that is failing probably isn't showing up in the GUI at all due 
to the error, the tool that parses the output will throw this away.  The GUI 
currently doesn't display any indication of error with the underlying tools - 
that is an enhancement that will be added with future development.  For now 
it is necessary to either read the logs, or do a test by hand to verify 
functionality.  

Hope this helps;
