perfSONAR User Q&A and Other Discussion

[John-Paul Robinson <>]

Hi,

I have a throughput test that had been gathering data from src-dst and dst-src but as of Oct 10 has stopped gathering data for the dst-src direction.  In this test, my perfsonar node is defined as the dst and the remote node is defined as the src.

If I run bwctl from the command line of my perfsonar node have still gotten results in both directions that match the performance I was seeing prior too Oct 10.

I've tried to debug this test to see if I'm having name resolution errors by adding alternate entries for the host using the alias name published in the location service, the official hostname and the IP address. However, it appears that multiple entries for a host within a test are collapsed  into a single test.  Is this correct or should I expect to see an entry for each host definition in my test results?

I've even tried to define a distinct throughput test with just this one host in it but I still don't see any results appearing for the host.

Could I get some clarity on the expected behavior and suggestions for alternatives to debug this issue?

Looking in the regular testing log I see information like the following which suggests the tests are running:
