perfSONAR User Q&A and Other Discussion

["Andrew Lake" <>]

Hi Robert,

I think the problem is that some of your hosts only do OWAMP, but are included in BWCTL meshes with the current class structures (and vice versa). Right now you just have one class, owamp_agents, that matches everything. I think you may want to add a "tag latency_host” in the host class definition of your MeshConfig.conf file. Likewise, I think you also want to add a second bwctl_agents class (or similarly named) with a "tag throughput_host” and use that class in your BWCTL meshes. That should get rid of the errors.

Thanks,

Andy

My statically defined json(in case we need a reference):

Dynamically created Json:

json for the hosts:

https://perfsonar1.research-lan.colostate.edu/auto.json

No problem!

Hi Robert,

Could you send me a link to the generated JSON (or attach it into a file if its firewalled off)? It looks like in theory it should be able to find an MA as you said.

Thanks,

Andy

Hello!

I'm trying to use a dynamic mesh to run tests on and update maddash to display with no luck so far.  Any help is appreciated.

I'm getting the below error when I try to run ( /opt/perfsonar_ps/mesh_config/bin/generate_gui_configuration ) to update maddash.  When I run generate_configuration I don't notice the tests being created.  My hunch is it's the lookup_hosts file not providing the correct measurement archive, but I think I've asked all the hosts to point to perfsonar1-research-lan.colostate.edu instead of using their local MAs(which would be cool to do as well).

perfsonar1.research-lan.colostate.edu/dyn.json - dynamic tests

perfsonar1.research-lan.colostate.edu/auto.json - list of hosts
