Looks like the read_url in your meashconfig for uwyo.edu is wrong. It’s 
"http://perfsonar.uwyo.edu8085/perfSONAR_PS/services/pSB” currently but 
should be http://perfsonar.uwyo.edu/esmond/perfsonar/archive/

In general, yes the top of the box is the test with row sending to column as 
initiated by the row host. This can vary slightly depending on your 
configuration (for example, if only one side is capable of initiating tests) 
but that doesn’t seem to apply here. Let’s get #3 fixed and come back to his 
if it’s still an issue.

You need to run /opt/perfsonar_ps/mesh_config/bin/generate_gui_configuration 
(as opposed to generate_configuration) to get the MaDDash YAML. If you don’t 
have that script run “yum install perl-perfSONAR_PS-MeshConfig-GUIAgent”. 
Changing that should hopefully fix things.
