perfSONAR User Q&A and Other Discussion

[David Koski <>]

The issue I have is we have a default external interface set.  When I add a single latency test, I get 2 graphs such as:

Source	Destination	Bidirectional	Forward Direction Loss (Past 30 minutes)	Reverse Direction Loss (Past 30 minutes)	Graph
core-xxx-10g (1.1.1.2)	core-xxx-10g (1.1.1.2)	No	0.00%	*	Select   4 hours   12 hours  1 Day  1 week
core-yyy-10g (2.2.2.3)	core-xxx-10g(1.1.1.2)	No	0.00%	*	Select   4 hours   12 hours  1 Day  1 week

So the question is, should I see the first graph which really is a graph and test from the internal default interface to the internal default interface of the local perfsonar box.  The second graph is expected as it is the test I've scheduled.  With this example, there is only 1 scheduled test, but I'm getting the two active tests from it, and I'm confused why I'm seeing a graph from the default interface to the default interface.

         Thanks

I'm not 100% sure I understand your question, but I think this is expected behavior.

If the "external address" changes, the tests will look like new tests to the database.

Perhaps if you send a screen shot it might help me better understand the issue.

I'm relatively new to setting up PerfSOANR-PS and had a question in regards to scheduled testing.

I had to adjust our default interface in discover_external_addresses to the correct interface since the box has multiple.  After doing so, I scheduled a quick OWAMP test with a single host.

What I noticed is that I'm getting 2 graphs in the OWAMP output.  One between the perfsonar default interface and the host I scheduled it for, the other with a source and destination address of the external default interface on the perfsonar box itself.

Is that correct?  The graph with the source and destination of the external default interface seems a bit confusing to me.  I haven't seen this in other example deployments and was wondering if I'm missing something with the configuration.  

       Thanks
