perfSONAR User Q&A and Other Discussion

[Kate Adams <>]

As a follow on question, how do you restart everything necessary?

There's a host that's spam-bandwidth testing us, and I commented it out of the mesh config file, ran /usr/lib/perfsonar/bin/build_json and copied the result to /opt/perfsonar_ps/mesh/gpn.json

Then ran the following commands:

sudo service maddash-server restart

sudo service perfsonar-meshconfig-agent restart 

sudo service perfsonar-meshconfig-guiagent restart

The host is still on our maddash, and pscheduler is still scheduling tests from it.  Are there other commands to run?

Casey,

Thank you very much.  This is very helpful and I followed your instructions.

Kate,

     I didn't think of it earlier, but I don't have to just point you to the documentation, I also have examples from my own files.  In the KanREN mesh, I specifically do IPv4 tests and IPv6 tests separately.  Here are the OWAMP tests only.  You obviously won't want to copy ALL of the options, but you can see what the ipv4_only and ipv6_only directives look like in action.

<test_spec owamp_test_v4>

  type              perfsonarbuoy/owamp

  packet_interval   0.01

  loss_threshold    10

  session_count     18000

  sample_count      6000

  packet_padding    0

  bucket_width      0.001

  force_bidirectional 1

  ipv4_only 1

</test_spec>

<test_spec owamp_test>

  type              perfsonarbuoy/owamp

  packet_interval   0.01

  loss_threshold    10

  session_count     18000

  sample_count      6000

  packet_padding    0

  bucket_width      0.001

  force_bidirectional 1

  ipv6_only 1

</test_spec>

These are from the mesh.conf file (before it is converted to JSON).

Kate,

     The developers or others can come along later and correct me if I'm wrong, but I'm pretty sure you'd set that in your mesh config file (in the test specification section for each test type).

Hello All,

The whole path that we'd need for proper v6 testing is unavailable, but IPv6 is enabled on our perfsonar host.

I'd like to force v4 testing only and see if that clears up some issues we have with the maddash not reporting results.

The documentation says 

" There is both a ipv4_only and ipv6_only option you can set in the test parameters of a mesh config. Setting them both at the same time gives an error."

What file does this refer to?
