perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <>]

Hi Daniel,

Thanks for the tip and I have found it configuration in the web gui.

However, I am stuck again!  I started the system with one configured NIC and 
scheduled "owamp" test.  Later, I enabled the second NIC on the same subnet, 
now the "Throughtput/Latency Graphs" won't displayed at all, a perpetual 
spinning circles goes around (even after I disabled the second NIC).  

If I have two NICs in the the same host on the same subnet, will the outgoing 
tests use the first interface only (default route on the default NIC)?  While 
both interface were up, the "local services" show all tests running on both 
NICs, how can I configure the incoming tests for individual NIC.  With two 
NICs on the same subnet, the incoming test comes the second NIC, but the 
outgoing packets could be sent out on the first NIC, is that right?  

Thank you.

Zhi-Wei,

This is configurable in the same place as you configure all the rest of the 
test parameters, underneath "Toolkit Administration" on the left in the 
section "Configure Tests".

There is now a new field called "Interface" under the Test Parameters section 
of a test that defaults to "Default" which was the old behavior. You can 
change this to instruct the test to use a specific interface instead. All 
previously configured tests should have "Default" set as their Interface 
option when upgrading.

Hope that helps.

-Dan
