perfSONAR User Q&A and Other Discussion

Hi Andy and Aaron,

Has there been any progress on documenting regular_testing.conf? I’d like to 
tweak my test, but it’s a bit confusing trying to translate this to 
bwing/owamp. I’m using the mesh_agent to create a json that my test hosts 
retrieve, they all have 'force_bwctl_owamp 1’ set in their agent configs.

<test_spec owamp_test>
  # Define a test spec for doing jitter, loss and latency testing
  type              perfsonarbuoy/owamp  # Perform a constant low-bandwidth 
OWAMP test
  packet_interval   0.01                 # Send 100 packets every second 
(i.e. pause 0.01 seconds between each packet)
  loss_threshold    10                   # Wait no more than 10 seconds for a 
response
  session_count     18000                # Refresh the test every half hour 
(once every 18000 packets)
  sample_count      300                  # Send results back every 30 seconds 
(once every 300 packets)
  packet_padding    0                    # The size of the packets (not 
including the IP/UDP headers)
  bucket_width      0.001                # The granularity of the measurements
</test_spec>

The config that ends up on my test hosts has schedule type ‘streaming’, how 
can I get that to ‘regular_intervals’ and define the interval?

Thanks,
--Ty
